+# Googletest Mocking (gMock) Framework
+
+### Overview
+
+Google's framework for writing and using C++ mock classes. It can help you
+derive better designs of your system and write better tests.
+
+It is inspired by:
+
+* [jMock](http://www.jmock.org/)
+* [EasyMock](http://www.easymock.org/)
+* [Hamcrest](http://code.google.com/p/hamcrest/)
+
+It is designed with C++'s specifics in mind.
+
+gMock:
+
+- Provides a declarative syntax for defining mocks.
+- Can define partial (hybrid) mocks, which are a cross of real and mock
+ objects.
+- Handles functions of arbitrary types and overloaded functions.
+- Comes with a rich set of matchers for validating function arguments.
+- Uses an intuitive syntax for controlling the behavior of a mock.
+- Does automatic verification of expectations (no record-and-replay needed).
+- Allows arbitrary (partial) ordering constraints on function calls to be
+ expressed.
+- Lets a user extend it by defining new matchers and actions.
+- Does not use exceptions.
+- Is easy to learn and use.
+
+Details and examples can be found here:
+
+* [gMock for Dummies](docs/for_dummies.md)
+* [Legacy gMock FAQ](docs/gmock_faq.md)
+* [gMock Cookbook](docs/cook_book.md)
+* [gMock Cheat Sheet](docs/cheat_sheet.md)
+
+Please note that code under scripts/generator/ is from the
+[cppclean project](http://code.google.com/p/cppclean/) and under the Apache
+License, which is different from GoogleMock's license.
+
+GoogleMock is a part of
+[GoogleTest C++ testing framework](http://github.com/google/googletest/) and a
+subject to the same requirements.

+## Defining a Mock Class
+
+### Mocking a Normal Class {#MockClass}
+
+Given
+
+```cpp
+class Foo {
+ ...
+ virtual ~Foo();
+ virtual int GetSize() const = 0;
+ virtual string Describe(const char* name) = 0;
+ virtual string Describe(int type) = 0;
+ virtual bool Process(Bar elem, int count) = 0;
+};
+```
+
+(note that `~Foo()` **must** be virtual) we can define its mock as
+
+```cpp
+#include "gmock/gmock.h"
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(int, GetSize, (), (const, override));
+ MOCK_METHOD(string, Describe, (const char* name), (override));
+ MOCK_METHOD(string, Describe, (int type), (override));
+ MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
+};
+```
+
+To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
+which warns on all uninteresting calls, or a "strict" mock, which treats them as
+failures:
+
+```cpp
+using ::testing::NiceMock;
+using ::testing::NaggyMock;
+using ::testing::StrictMock;
+
+NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
+NaggyMock<MockFoo> naggy_foo; // The type is a subclass of MockFoo.
+StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
+```
+
+**Note:** A mock object is currently naggy by default. We may make it nice by
+default in the future.
+
+### Mocking a Class Template {#MockTemplate}
+
+Class templates can be mocked just like any class.
+
+To mock
+
+```cpp
+template <typename Elem>
+class StackInterface {
+ ...
+ virtual ~StackInterface();
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+```
+
+(note that all member functions that are mocked, including `~StackInterface()`
+**must** be virtual).
+
+```cpp
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ ...
+ MOCK_METHOD(int, GetSize, (), (const, override));
+ MOCK_METHOD(void, Push, (const Elem& x), (override));
+};
+```
+
+### Specifying Calling Conventions for Mock Functions
+
+If your mock function doesn't use the default calling convention, you can
+specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
+For example,
+
+```cpp
+ MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
+ MOCK_METHOD(int, Bar, (double x, double y),
+ (const, Calltype(STDMETHODCALLTYPE)));
+```
+
+where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
+
+## Using Mocks in Tests {#UsingMocks}
+
+The typical work flow is:
+
+1. Import the gMock names you need to use. All gMock symbols are in the
+ `testing` namespace unless they are macros or otherwise noted.
+2. Create the mock objects.
+3. Optionally, set the default actions of the mock objects.
+4. Set your expectations on the mock objects (How will they be called? What
+ will they do?).
+5. Exercise code that uses the mock objects; if necessary, check the result
+ using googletest assertions.
+6. When a mock object is destructed, gMock automatically verifies that all
+ expectations on it have been satisfied.
+
+Here's an example:
+
+```cpp
+using ::testing::Return; // #1
+
+TEST(BarTest, DoesThis) {
+ MockFoo foo; // #2
+
+ ON_CALL(foo, GetSize()) // #3
+ .WillByDefault(Return(1));
+ // ... other default actions ...
+
+ EXPECT_CALL(foo, Describe(5)) // #4
+ .Times(3)
+ .WillRepeatedly(Return("Category 5"));
+ // ... other expectations ...
+
+ EXPECT_EQ("good", MyProductionFunction(&foo)); // #5
+} // #6
+```
+
+## Setting Default Actions {#OnCall}
+
+gMock has a **built-in default action** for any function that returns `void`,
+`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
+the default-constructed value, if one exists for the given type.
+
+To customize the default action for functions with return type *`T`*:
+
+```cpp
+using ::testing::DefaultValue;
+
+// Sets the default value to be returned. T must be CopyConstructible.
+DefaultValue<T>::Set(value);
+// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
+// T MakeT();
+DefaultValue<T>::SetFactory(&MakeT);
+// ... use the mocks ...
+// Resets the default value.
+DefaultValue<T>::Clear();
+```
+
+Example usage:
+
+```cpp
+ // Sets the default action for return type std::unique_ptr<Buzz> to
+ // creating a new Buzz every time.
+ DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
+ [] { return MakeUnique<Buzz>(AccessLevel::kInternal); });
+
+ // When this fires, the default action of MakeBuzz() will run, which
+ // will return a new Buzz object.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
+
+ auto buzz1 = mock_buzzer_.MakeBuzz("hello");
+ auto buzz2 = mock_buzzer_.MakeBuzz("hello");
+ EXPECT_NE(nullptr, buzz1);
+ EXPECT_NE(nullptr, buzz2);
+ EXPECT_NE(buzz1, buzz2);
+
+ // Resets the default action for return type std::unique_ptr<Buzz>,
+ // to avoid interfere with other tests.
+ DefaultValue<std::unique_ptr<Buzz>>::Clear();
+```
+
+To customize the default action for a particular method of a specific mock
+object, use `ON_CALL()`. `ON_CALL()` has a similar syntax to `EXPECT_CALL()`,
+but it is used for setting default behaviors (when you do not require that the
+mock method is called). See [here](cook_book.md#UseOnCall) for a more detailed
+discussion.
+
+```cpp
+ON_CALL(mock-object, method(matchers))
+ .With(multi-argument-matcher) ?
+ .WillByDefault(action);
+```
+
+## Setting Expectations {#ExpectCall}
+
+`EXPECT_CALL()` sets **expectations** on a mock method (How will it be called?
+What will it do?):
+
+```cpp
+EXPECT_CALL(mock-object, method (matchers)?)
+ .With(multi-argument-matcher) ?
+ .Times(cardinality) ?
+ .InSequence(sequences) *
+ .After(expectations) *
+ .WillOnce(action) *
+ .WillRepeatedly(action) ?
+ .RetiresOnSaturation(); ?
+```
+
+For each item above, `?` means it can be used at most once, while `*` means it
+can be used any number of times.
+
+In order to pass, `EXPECT_CALL` must be used before the calls are actually made.
+
+The `(matchers)` is a comma-separated list of matchers that correspond to each
+of the arguments of `method`, and sets the expectation only for calls of
+`method` that matches all of the matchers.
+
+If `(matchers)` is omitted, the expectation is the same as if the matchers were
+set to anything matchers (for example, `(_, _, _, _)` for a four-arg method).
+
+If `Times()` is omitted, the cardinality is assumed to be:
+
+* `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
+* `Times(n)` when there are `n` `WillOnce()`s but no `WillRepeatedly()`, where
+ `n` >= 1; or
+* `Times(AtLeast(n))` when there are `n` `WillOnce()`s and a
+ `WillRepeatedly()`, where `n` >= 0.
+
+A method with no `EXPECT_CALL()` is free to be invoked *any number of times*,
+and the default action will be taken each time.
+
+## Matchers {#MatcherList}
+
+<!-- GOOGLETEST_CM0020 DO NOT DELETE -->
+
+A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
+`EXPECT_CALL()`, or use it to validate a value directly using two macros:
+
+<!-- mdformat off(github rendering does not support multiline tables) -->
+| Macro | Description |
+| :----------------------------------- | :------------------------------------ |
+| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
+| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
+<!-- mdformat on -->
+
+**Note:** Although equality matching via `EXPECT_THAT(actual_value,
+expected_value)` is supported, prefer to make the comparison explicit via
+`EXPECT_THAT(actual_value, Eq(expected_value))` or `EXPECT_EQ(actual_value,
+expected_value)`.
+
+Built-in matchers (where `argument` is the function argument, e.g.
+`actual_value` in the example above, or when used in the context of
+`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
+divided into several categories:
+
+### Wildcard
+
+Matcher | Description
+:-------------------------- | :-----------------------------------------------
+`_` | `argument` can be any value of the correct type.
+`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
+
+### Generic Comparison
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :--------------------- | :-------------------------------------------------- |
+| `Eq(value)` or `value` | `argument == value` |
+| `Ge(value)` | `argument >= value` |
+| `Gt(value)` | `argument > value` |
+| `Le(value)` | `argument <= value` |
+| `Lt(value)` | `argument < value` |
+| `Ne(value)` | `argument != value` |
+| `IsFalse()` | `argument` evaluates to `false` in a Boolean context. |
+| `IsTrue()` | `argument` evaluates to `true` in a Boolean context. |
+| `IsNull()` | `argument` is a `NULL` pointer (raw or smart). |
+| `NotNull()` | `argument` is a non-null pointer (raw or smart). |
+| `Optional(m)` | `argument` is `optional<>` that contains a value matching `m`. (For testing whether an `optional<>` is set, check for equality with `nullopt`. You may need to use `Eq(nullopt)` if the inner type doesn't have `==`.)|
+| `VariantWith<T>(m)` | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
+| `Ref(variable)` | `argument` is a reference to `variable`. |
+| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
+<!-- mdformat on -->
+
+Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
+destructed later. If the compiler complains that `value` doesn't have a public
+copy constructor, try wrap it in `std::ref()`, e.g.
+`Eq(std::ref(non_copyable_value))`. If you do that, make sure
+`non_copyable_value` is not changed afterwards, or the meaning of your matcher
+will be changed.
+
+`IsTrue` and `IsFalse` are useful when you need to use a matcher, or for types
+that can be explicitly converted to Boolean, but are not implicitly converted to
+Boolean. In other cases, you can use the basic
+[`EXPECT_TRUE` and `EXPECT_FALSE`](../../googletest/docs/primer#basic-assertions)
+assertions.
+
+### Floating-Point Matchers {#FpMatchers}
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------------- | :--------------------------------- |
+| `DoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
+| `FloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
+| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
+| `NanSensitiveFloatEq(a_float)` | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
+| `IsNan()` | `argument` is any floating-point type with a NaN value. |
+<!-- mdformat on -->
+
+The above matchers use ULP-based comparison (the same as used in googletest).
+They automatically pick a reasonable error bound based on the absolute value of
+the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
+which requires comparing two NaNs for equality to return false. The
+`NanSensitive*` version instead treats two NaNs as equal, which is often what a
+user wants.
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------------------------------ | :----------------------- |
+| `DoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
+| `FloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
+| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+| `NanSensitiveFloatNear(a_float, max_abs_error)` | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
+<!-- mdformat on -->
+
+### String Matchers
+
+The `argument` can be either a C string or a C++ string object:
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :---------------------- | :------------------------------------------------- |
+| `ContainsRegex(string)` | `argument` matches the given regular expression. |
+| `EndsWith(suffix)` | `argument` ends with string `suffix`. |
+| `HasSubstr(string)` | `argument` contains `string` as a sub-string. |
+| `MatchesRegex(string)` | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
+| `StartsWith(prefix)` | `argument` starts with string `prefix`. |
+| `StrCaseEq(string)` | `argument` is equal to `string`, ignoring case. |
+| `StrCaseNe(string)` | `argument` is not equal to `string`, ignoring case. |
+| `StrEq(string)` | `argument` is equal to `string`. |
+| `StrNe(string)` | `argument` is not equal to `string`. |
+<!-- mdformat on -->
+
+`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
+use the regular expression syntax defined
+[here](../../googletest/docs/advanced.md#regular-expression-syntax). All of
+these matchers, except `ContainsRegex()` and `MatchesRegex()` work for wide
+strings as well.
+
+### Container Matchers
+
+Most STL-style containers support `==`, so you can use `Eq(expected_container)`
+or simply `expected_container` to match a container exactly. If you want to
+write the elements in-line, match them more flexibly, or get more informative
+messages, you can use:
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :---------------------------------------- | :------------------------------- |
+| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
+| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
+| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
+| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
+| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
+| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
+| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
+| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
+| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
+| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
+| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
+| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
+| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
+| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |
+<!-- mdformat on -->
+
+**Notes:**
+
+* These matchers can also match:
+ 1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
+ and
+ 2. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
+ int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
+* The array being matched may be multi-dimensional (i.e. its elements can be
+ arrays).
+* `m` in `Pointwise(m, ...)` should be a matcher for `::std::tuple<T, U>`
+ where `T` and `U` are the element type of the actual container and the
+ expected container, respectively. For example, to compare two `Foo`
+ containers where `Foo` doesn't support `operator==`, one might write:
+
+ ```cpp
+ using ::std::get;
+ MATCHER(FooEq, "") {
+ return std::get<0>(arg).Equals(std::get<1>(arg));
+ }
+ ...
+ EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
+ ```
+
+### Member Matchers
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------------ | :----------------------------------------- |
+| `Field(&class::field, m)` | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
+| `Key(e)` | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
+| `Pair(m1, m2)` | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
+| `FieldsAre(m...)` | `argument` is a compatible object where each field matches piecewise with `m...`. A compatible object is any that supports the `std::tuple_size<Obj>`+`get<I>(obj)` protocol. In C++17 and up this also supports types compatible with structured bindings, like aggregates. |
+| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
+<!-- mdformat on -->
+
+### Matching the Result of a Function, Functor, or Callback
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :--------------- | :------------------------------------------------ |
+| `ResultOf(f, m)` | `f(argument)` matches matcher `m`, where `f` is a function or functor. |
+<!-- mdformat on -->
+
+### Pointer Matchers
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------ | :---------------------------------------------- |
+| `Address(m)` | the result of `std::addressof(argument)` matches `m`. |
+| `Pointee(m)` | `argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`. |
+| `Pointer(m)` | `argument` (either a smart pointer or a raw pointer) contains a pointer that matches `m`. `m` will match against the raw pointer regardless of the type of `argument`. |
+| `WhenDynamicCastTo<T>(m)` | when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |

+
+### Multi-argument Matchers {#MultiArgMatchers}
+
+Technically, all matchers match a *single* value. A "multi-argument" matcher is
+just one that matches a *tuple*. The following matchers can be used to match a
+tuple `(x, y)`:
+
+Matcher | Description
+:------ | :----------
+`Eq()` | `x == y`
+`Ge()` | `x >= y`
+`Gt()` | `x > y`
+`Le()` | `x <= y`
+`Lt()` | `x < y`
+`Ne()` | `x != y`
+
+You can use the following selectors to pick a subset of the arguments (or
+reorder them) to participate in the matching:
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------- | :---------------------------------------------- |
+| `AllArgs(m)` | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
+| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
+<!-- mdformat on -->
+
+### Composite Matchers
+
+You can make a matcher from one or more other matchers:
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------------------------- | :-------------------------------------- |
+| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
+| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
+| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
+| `Not(m)` | `argument` doesn't match matcher `m`. |
+<!-- mdformat on -->
+
+<!-- GOOGLETEST_CM0028 DO NOT DELETE -->
+
+### Adapters for Matchers
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :---------------------- | :------------------------------------ |
+| `MatcherCast<T>(m)` | casts matcher `m` to type `Matcher<T>`. |
+| `SafeMatcherCast<T>(m)` | [safely casts](cook_book.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
+| `Truly(predicate)` | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |
+<!-- mdformat on -->
+
+`AddressSatisfies(callback)` and `Truly(callback)` take ownership of `callback`,
+which must be a permanent callback.
+
+### Using Matchers as Predicates {#MatchersAsPredicatesCheat}
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :---------------------------- | :------------------------------------------ |
+| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
+| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
+| `Value(value, m)` | evaluates to `true` if `value` matches `m`. |
+<!-- mdformat on -->
+
+### Defining Matchers
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :----------------------------------- | :------------------------------------ |
+| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
+| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a matcher `IsDivisibleBy(n)` to match a number divisible by `n`. |
+| `MATCHER_P2(IsBetween, a, b, absl::StrCat(negation ? "isn't" : "is", " between ", PrintToString(a), " and ", PrintToString(b))) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
+<!-- mdformat on -->
+
+**Notes:**
+
+1. The `MATCHER*` macros cannot be used inside a function or class.
+2. The matcher body must be *purely functional* (i.e. it cannot have any side
+ effect, and the result must not depend on anything other than the value
+ being matched and the matcher parameters).
+3. You can use `PrintToString(x)` to convert a value `x` of any type to a
+ string.
+
+## Actions {#ActionList}
+
+**Actions** specify what a mock function should do when invoked.
+
+### Returning a Value
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :-------------------------------- | :-------------------------------------------- |
+| `Return()` | Return from a `void` mock function. |
+| `Return(value)` | Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
+| `ReturnArg<N>()` | Return the `N`-th (0-based) argument. |
+| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different object is created each time. |
+| `ReturnNull()` | Return a null pointer. |
+| `ReturnPointee(ptr)` | Return the value pointed to by `ptr`. |
+| `ReturnRef(variable)` | Return a reference to `variable`. |
+| `ReturnRefOfCopy(value)` | Return a reference to a copy of `value`; the copy lives as long as the action. |
+| `ReturnRoundRobin({a1, ..., ak})` | Each call will return the next `ai` in the list, starting at the beginning when the end of the list is reached. |
+<!-- mdformat on -->
+
+### Side Effects
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :--------------------------------- | :-------------------------------------- |
+| `Assign(&variable, value)` | Assign `value` to variable. |
+| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
+| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
+| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
+| `SetArgReferee<N>(value)` | Assign `value` to the variable referenced by the `N`-th (0-based) argument. |
+| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
+| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
+| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
+| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
+| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |
+<!-- mdformat on -->
+
+### Using a Function, Functor, or Lambda as an Action
+
+In the following, by "callable" we mean a free function, `std::function`,
+functor, or lambda.
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :---------------------------------- | :------------------------------------- |
+| `f` | Invoke f with the arguments passed to the mock function, where f is a callable. |
+| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
+| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
+| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
+| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
+| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
+<!-- mdformat on -->
+
+The return value of the invoked function is used as the return value of the
+action.
+
+When defining a callable to be used with `Invoke*()`, you can declare any unused
+parameters as `Unused`:
+
+```cpp
+using ::testing::Invoke;
+double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
+...
+EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
+```
+
+`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
+`callback`, which must be permanent. The type of `callback` must be a base
+callback type instead of a derived one, e.g.
+
+```cpp
+ BlockingClosure* done = new BlockingClosure;
+ ... Invoke(done) ...; // This won't compile!
+
+ Closure* done2 = new BlockingClosure;
+ ... Invoke(done2) ...; // This works.
+```
+
+In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
+wrap it inside `std::ref()`. For example,
+
+```cpp
+using ::testing::InvokeArgument;
+...
+InvokeArgument<2>(5, string("Hi"), std::ref(foo))
+```
+
+calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
+value, and `foo` by reference.
+
+### Default Action
+
+<!-- mdformat off(no multiline tables) -->
+| Matcher | Description |
+| :------------ | :----------------------------------------------------- |
+| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
+<!-- mdformat on -->
+
+**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
+composite action - trying to do so will result in a run-time error.
+
+<!-- GOOGLETEST_CM0032 DO NOT DELETE -->
+
+### Composite Actions
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :----------------------------- | :------------------------------------------ |
+| `DoAll(a1, a2, ..., an)` | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void and will receive a readonly view of the arguments. |
+| `IgnoreResult(a)` | Perform action `a` and ignore its result. `a` must not return void. |
+| `WithArg<N>(a)` | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
+| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
+| `WithoutArgs(a)` | Perform action `a` without any arguments. |
+<!-- mdformat on -->
+
+### Defining Actions
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :--------------------------------- | :-------------------------------------- |
+| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
+| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
+| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
+<!-- mdformat on -->
+
+The `ACTION*` macros cannot be used inside a function or class.
+
+## Cardinalities {#CardinalityList}
+
+These are used in `Times()` to specify how many times a mock function will be
+called:
+
+<!-- mdformat off(no multiline tables) -->
+| | |
+| :---------------- | :----------------------------------------------------- |
+| `AnyNumber()` | The function can be called any number of times. |
+| `AtLeast(n)` | The call is expected at least `n` times. |
+| `AtMost(n)` | The call is expected at most `n` times. |
+| `Between(m, n)` | The call is expected between `m` and `n` (inclusive) times. |
+| `Exactly(n) or n` | The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0. |
+<!-- mdformat on -->
+
+## Expectation Order
+
+By default, the expectations can be matched in *any* order. If some or all
+expectations must be matched in a given order, there are two ways to specify it.
+They can be used either independently or together.
+
+### The After Clause {#AfterClause}
+
+```cpp
+using ::testing::Expectation;
+...
+Expectation init_x = EXPECT_CALL(foo, InitX());
+Expectation init_y = EXPECT_CALL(foo, InitY());
+EXPECT_CALL(foo, Bar())
+ .After(init_x, init_y);
+```
+
+says that `Bar()` can be called only after both `InitX()` and `InitY()` have
+been called.
+
+If you don't know how many pre-requisites an expectation has when you write it,
+you can use an `ExpectationSet` to collect them:
+
+```cpp
+using ::testing::ExpectationSet;
+...
+ExpectationSet all_inits;
+for (int i = 0; i < element_count; i++) {
+ all_inits += EXPECT_CALL(foo, InitElement(i));
+}
+EXPECT_CALL(foo, Bar())
+ .After(all_inits);
+```
+
+says that `Bar()` can be called only after all elements have been initialized
+(but we don't care about which elements get initialized before the others).
+
+Modifying an `ExpectationSet` after using it in an `.After()` doesn't affect the
+meaning of the `.After()`.
+
+### Sequences {#UsingSequences}
+
+When you have a long chain of sequential expectations, it's easier to specify
+the order using **sequences**, which don't require you to given each expectation
+in the chain a different name. *All expected calls* in the same sequence must
+occur in the order they are specified.
+
+```cpp
+using ::testing::Return;
+using ::testing::Sequence;
+Sequence s1, s2;
+...
+EXPECT_CALL(foo, Reset())
+ .InSequence(s1, s2)
+ .WillOnce(Return(true));
+EXPECT_CALL(foo, GetSize())
+ .InSequence(s1)
+ .WillOnce(Return(1));
+EXPECT_CALL(foo, Describe(A<const char*>()))
+ .InSequence(s2)
+ .WillOnce(Return("dummy"));
+```
+
+says that `Reset()` must be called before *both* `GetSize()` *and* `Describe()`,
+and the latter two can occur in any order.
+
+To put many expectations in a sequence conveniently:
+
+```cpp
+using ::testing::InSequence;
+{
+ InSequence seq;
+
+ EXPECT_CALL(...)...;
+ EXPECT_CALL(...)...;
+ ...
+ EXPECT_CALL(...)...;
+}
+```
+
+says that all expected calls in the scope of `seq` must occur in strict order.
+The name `seq` is irrelevant.
+
+## Verifying and Resetting a Mock
+
+gMock will verify the expectations on a mock object when it is destructed, or
+you can do it earlier:
+
+```cpp
+using ::testing::Mock;
+...
+// Verifies and removes the expectations on mock_obj;
+// returns true if and only if successful.
+Mock::VerifyAndClearExpectations(&mock_obj);
+...
+// Verifies and removes the expectations on mock_obj;
+// also removes the default actions set by ON_CALL();
+// returns true if and only if successful.
+Mock::VerifyAndClear(&mock_obj);
+```
+
+You can also tell gMock that a mock object can be leaked and doesn't need to be
+verified:
+
+```cpp
+Mock::AllowLeak(&mock_obj);
+```
+
+## Mock Classes
+
+gMock defines a convenient mock class template
+
+```cpp
+class MockFunction<R(A1, ..., An)> {
+ public:
+ MOCK_METHOD(R, Call, (A1, ..., An));
+};
+```
+
+See this [recipe](cook_book.md#using-check-points) for one application of it.
+
+## Flags
+
+<!-- mdformat off(no multiline tables) -->
+| Flag | Description |
+| :----------------------------- | :---------------------------------------- |
+| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
+| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

+# gMock Cookbook
+
+<!-- GOOGLETEST_CM0012 DO NOT DELETE -->
+
+You can find recipes for using gMock here. If you haven't yet, please read
+[the dummy guide](for_dummies.md) first to make sure you understand the basics.
+
+**Note:** gMock lives in the `testing` name space. For readability, it is
+recommended to write `using ::testing::Foo;` once in your file before using the
+name `Foo` defined by gMock. We omit such `using` statements in this section for
+brevity, but you should do it in your own code.
+
+<!-- GOOGLETEST_CM0035 DO NOT DELETE -->
+
+## Creating Mock Classes
+
+Mock classes are defined as normal classes, using the `MOCK_METHOD` macro to
+generate mocked methods. The macro gets 3 or 4 parameters:
+
+```cpp
+class MyMock {
+ public:
+ MOCK_METHOD(ReturnType, MethodName, (Args...));
+ MOCK_METHOD(ReturnType, MethodName, (Args...), (Specs...));
+};
+```
+
+The first 3 parameters are simply the method declaration, split into 3 parts.
+The 4th parameter accepts a closed list of qualifiers, which affect the
+generated method:
+
+* **`const`** - Makes the mocked method a `const` method. Required if
+ overriding a `const` method.
+* **`override`** - Marks the method with `override`. Recommended if overriding
+ a `virtual` method.
+* **`noexcept`** - Marks the method with `noexcept`. Required if overriding a
+ `noexcept` method.
+* **`Calltype(...)`** - Sets the call type for the method (e.g. to
+ `STDMETHODCALLTYPE`), useful in Windows.
+* **`ref(...)`** - Marks the method with the reference qualification
+ specified. Required if overriding a method that has reference
+ qualifications. Eg `ref(&)` or `ref(&&)`.
+
+### Dealing with unprotected commas
+
+Unprotected commas, i.e. commas which are not surrounded by parentheses, prevent
+`MOCK_METHOD` from parsing its arguments correctly:
+
+```cpp {.bad}
+class MockFoo {
+ public:
+ MOCK_METHOD(std::pair<bool, int>, GetPair, ()); // Won't compile!
+ MOCK_METHOD(bool, CheckMap, (std::map<int, double>, bool)); // Won't compile!
+};
+```
+
+Solution 1 - wrap with parentheses:
+
+```cpp {.good}
+class MockFoo {
+ public:
+ MOCK_METHOD((std::pair<bool, int>), GetPair, ());
+ MOCK_METHOD(bool, CheckMap, ((std::map<int, double>), bool));
+};
+```
+
+Note that wrapping a return or argument type with parentheses is, in general,
+invalid C++. `MOCK_METHOD` removes the parentheses.
+
+Solution 2 - define an alias:
+
+```cpp {.good}
+class MockFoo {
+ public:
+ using BoolAndInt = std::pair<bool, int>;
+ MOCK_METHOD(BoolAndInt, GetPair, ());
+ using MapIntDouble = std::map<int, double>;
+ MOCK_METHOD(bool, CheckMap, (MapIntDouble, bool));
+};
+```
+
+### Mocking Private or Protected Methods
+
+You must always put a mock method definition (`MOCK_METHOD`) in a `public:`
+section of the mock class, regardless of the method being mocked being `public`,
+`protected`, or `private` in the base class. This allows `ON_CALL` and
+`EXPECT_CALL` to reference the mock function from outside of the mock class.
+(Yes, C++ allows a subclass to change the access level of a virtual function in
+the base class.) Example:
+
+```cpp
+class Foo {
+ public:
+ ...
+ virtual bool Transform(Gadget* g) = 0;
+
+ protected:
+ virtual void Resume();
+
+ private:
+ virtual int GetTimeOut();
+};
+
+class MockFoo : public Foo {
+ public:
+ ...
+ MOCK_METHOD(bool, Transform, (Gadget* g), (override));
+
+ // The following must be in the public section, even though the
+ // methods are protected or private in the base class.
+ MOCK_METHOD(void, Resume, (), (override));
+ MOCK_METHOD(int, GetTimeOut, (), (override));
+};
+```
+
+### Mocking Overloaded Methods
+
+You can mock overloaded functions as usual. No special attention is required:
+
+```cpp
+class Foo {
+ ...
+
+ // Must be virtual as we'll inherit from Foo.
+ virtual ~Foo();
+
+ // Overloaded on the types and/or numbers of arguments.
+ virtual int Add(Element x);
+ virtual int Add(int times, Element x);
+
+ // Overloaded on the const-ness of this object.
+ virtual Bar& GetBar();
+ virtual const Bar& GetBar() const;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(int, Add, (Element x), (override));
+ MOCK_METHOD(int, Add, (int times, Element x), (override));
+
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+ MOCK_METHOD(const Bar&, GetBar, (), (const, override));
+};
+```
+
+**Note:** if you don't mock all versions of the overloaded method, the compiler
+will give you a warning about some methods in the base class being hidden. To
+fix that, use `using` to bring them in scope:
+
+```cpp
+class MockFoo : public Foo {
+ ...
+ using Foo::Add;
+ MOCK_METHOD(int, Add, (Element x), (override));
+ // We don't want to mock int Add(int times, Element x);
+ ...
+};
+```
+
+### Mocking Class Templates
+
+You can mock class templates just like any class.
+
+```cpp
+template <typename Elem>
+class StackInterface {
+ ...
+ // Must be virtual as we'll inherit from StackInterface.
+ virtual ~StackInterface();
+
+ virtual int GetSize() const = 0;
+ virtual void Push(const Elem& x) = 0;
+};
+
+template <typename Elem>
+class MockStack : public StackInterface<Elem> {
+ ...
+ MOCK_METHOD(int, GetSize, (), (override));
+ MOCK_METHOD(void, Push, (const Elem& x), (override));
+};
+```
+
+### Mocking Non-virtual Methods {#MockingNonVirtualMethods}
+
+gMock can mock non-virtual functions to be used in Hi-perf dependency
+injection.<!-- GOOGLETEST_CM0017 DO NOT DELETE -->
+
+In this case, instead of sharing a common base class with the real class, your
+mock class will be *unrelated* to the real class, but contain methods with the
+same signatures. The syntax for mocking non-virtual methods is the *same* as
+mocking virtual methods (just don't add `override`):
+
+```cpp
+// A simple packet stream class. None of its members is virtual.
+class ConcretePacketStream {
+ public:
+ void AppendPacket(Packet* new_packet);
+ const Packet* GetPacket(size_t packet_number) const;
+ size_t NumberOfPackets() const;
+ ...
+};
+
+// A mock packet stream class. It inherits from no other, but defines
+// GetPacket() and NumberOfPackets().
+class MockPacketStream {
+ public:
+ MOCK_METHOD(const Packet*, GetPacket, (size_t packet_number), (const));
+ MOCK_METHOD(size_t, NumberOfPackets, (), (const));
+ ...
+};
+```
+
+Note that the mock class doesn't define `AppendPacket()`, unlike the real class.
+That's fine as long as the test doesn't need to call it.
+
+Next, you need a way to say that you want to use `ConcretePacketStream` in
+production code, and use `MockPacketStream` in tests. Since the functions are
+not virtual and the two classes are unrelated, you must specify your choice at
+*compile time* (as opposed to run time).
+
+One way to do it is to templatize your code that needs to use a packet stream.
+More specifically, you will give your code a template type argument for the type
+of the packet stream. In production, you will instantiate your template with
+`ConcretePacketStream` as the type argument. In tests, you will instantiate the
+same template with `MockPacketStream`. For example, you may write:
+
+```cpp
+template <class PacketStream>
+void CreateConnection(PacketStream* stream) { ... }
+
+template <class PacketStream>
+class PacketReader {
+ public:
+ void ReadPackets(PacketStream* stream, size_t packet_num);
+};
+```
+
+Then you can use `CreateConnection<ConcretePacketStream>()` and
+`PacketReader<ConcretePacketStream>` in production code, and use
+`CreateConnection<MockPacketStream>()` and `PacketReader<MockPacketStream>` in
+tests.
+
+```cpp
+ MockPacketStream mock_stream;
+ EXPECT_CALL(mock_stream, ...)...;
+ .. set more expectations on mock_stream ...
+ PacketReader<MockPacketStream> reader(&mock_stream);
+ ... exercise reader ...
+```
+
+### Mocking Free Functions
+
+It's possible to use gMock to mock a free function (i.e. a C-style function or a
+static method). You just need to rewrite your code to use an interface (abstract
+class).
+
+Instead of calling a free function (say, `OpenFile`) directly, introduce an
+interface for it and have a concrete subclass that calls the free function:
+
+```cpp
+class FileInterface {
+ public:
+ ...
+ virtual bool Open(const char* path, const char* mode) = 0;
+};
+
+class File : public FileInterface {
+ public:
+ ...
+ virtual bool Open(const char* path, const char* mode) {
+ return OpenFile(path, mode);
+ }
+};
+```
+
+Your code should talk to `FileInterface` to open a file. Now it's easy to mock
+out the function.
+
+This may seem like a lot of hassle, but in practice you often have multiple
+related functions that you can put in the same interface, so the per-function
+syntactic overhead will be much lower.
+
+If you are concerned about the performance overhead incurred by virtual
+functions, and profiling confirms your concern, you can combine this with the
+recipe for [mocking non-virtual methods](#MockingNonVirtualMethods).
+
+### Old-Style `MOCK_METHODn` Macros
+
+Before the generic `MOCK_METHOD` macro
+[was introduced in 2018](https://github.com/google/googletest/commit/c5f08bf91944ce1b19bcf414fa1760e69d20afc2),
+mocks where created using a family of macros collectively called `MOCK_METHODn`.
+These macros are still supported, though migration to the new `MOCK_METHOD` is
+recommended.
+
+The macros in the `MOCK_METHODn` family differ from `MOCK_METHOD`:
+
+* The general structure is `MOCK_METHODn(MethodName, ReturnType(Args))`,
+ instead of `MOCK_METHOD(ReturnType, MethodName, (Args))`.
+* The number `n` must equal the number of arguments.
+* When mocking a const method, one must use `MOCK_CONST_METHODn`.
+* When mocking a class template, the macro name must be suffixed with `_T`.
+* In order to specify the call type, the macro name must be suffixed with
+ `_WITH_CALLTYPE`, and the call type is the first macro argument.
+
+Old macros and their new equivalents:

+
+### The Nice, the Strict, and the Naggy {#NiceStrictNaggy}
+
+If a mock method has no `EXPECT_CALL` spec but is called, we say that it's an
+"uninteresting call", and the default action (which can be specified using
+`ON_CALL()`) of the method will be taken. Currently, an uninteresting call will
+also by default cause gMock to print a warning. (In the future, we might remove
+this warning by default.)
+
+However, sometimes you may want to ignore these uninteresting calls, and
+sometimes you may want to treat them as errors. gMock lets you make the decision
+on a per-mock-object basis.
+
+Suppose your test uses a mock class `MockFoo`:
+
+```cpp
+TEST(...) {
+ MockFoo mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+If a method of `mock_foo` other than `DoThis()` is called, you will get a
+warning. However, if you rewrite your test to use `NiceMock<MockFoo>` instead,
+you can suppress the warning:
+
+```cpp
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+`NiceMock<MockFoo>` is a subclass of `MockFoo`, so it can be used wherever
+`MockFoo` is accepted.
+
+It also works if `MockFoo`'s constructor takes some arguments, as
+`NiceMock<MockFoo>` "inherits" `MockFoo`'s constructors:
+
+```cpp
+using ::testing::NiceMock;
+
+TEST(...) {
+ NiceMock<MockFoo> mock_foo(5, "hi"); // Calls MockFoo(5, "hi").
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+}
+```
+
+The usage of `StrictMock` is similar, except that it makes all uninteresting
+calls failures:
+
+```cpp
+using ::testing::StrictMock;
+
+TEST(...) {
+ StrictMock<MockFoo> mock_foo;
+ EXPECT_CALL(mock_foo, DoThis());
+ ... code that uses mock_foo ...
+
+ // The test will fail if a method of mock_foo other than DoThis()
+ // is called.
+}
+```
+
+NOTE: `NiceMock` and `StrictMock` only affects *uninteresting* calls (calls of
+*methods* with no expectations); they do not affect *unexpected* calls (calls of
+methods with expectations, but they don't match). See
+[Understanding Uninteresting vs Unexpected Calls](#uninteresting-vs-unexpected).
+
+There are some caveats though (sadly they are side effects of C++'s
+limitations):
+
+1. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` only work for mock methods
+ defined using the `MOCK_METHOD` macro **directly** in the `MockFoo` class.
+ If a mock method is defined in a **base class** of `MockFoo`, the "nice" or
+ "strict" modifier may not affect it, depending on the compiler. In
+ particular, nesting `NiceMock` and `StrictMock` (e.g.
+ `NiceMock<StrictMock<MockFoo> >`) is **not** supported.
+2. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` may not work correctly if the
+ destructor of `MockFoo` is not virtual. We would like to fix this, but it
+ requires cleaning up existing tests.
+
+Finally, you should be **very cautious** about when to use naggy or strict
+mocks, as they tend to make tests more brittle and harder to maintain. When you
+refactor your code without changing its externally visible behavior, ideally you
+shouldn't need to update any tests. If your code interacts with a naggy mock,
+however, you may start to get spammed with warnings as the result of your
+change. Worse, if your code interacts with a strict mock, your tests may start
+to fail and you'll be forced to fix them. Our general recommendation is to use
+nice mocks (not yet the default) most of the time, use naggy mocks (the current
+default) when developing or debugging tests, and use strict mocks only as the
+last resort.
+
+### Simplifying the Interface without Breaking Existing Code {#SimplerInterfaces}
+
+Sometimes a method has a long list of arguments that is mostly uninteresting.
+For example:
+
+```cpp
+class LogSink {
+ public:
+ ...
+ virtual void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line,
+ const struct tm* tm_time,
+ const char* message, size_t message_len) = 0;
+};
+```
+
+This method's argument list is lengthy and hard to work with (the `message`
+argument is not even 0-terminated). If we mock it as is, using the mock will be
+awkward. If, however, we try to simplify this interface, we'll need to fix all
+clients depending on it, which is often infeasible.
+
+The trick is to redispatch the method in the mock class:
+
+```cpp
+class ScopedMockLog : public LogSink {
+ public:
+ ...
+ virtual void send(LogSeverity severity, const char* full_filename,
+ const char* base_filename, int line, const tm* tm_time,
+ const char* message, size_t message_len) {
+ // We are only interested in the log severity, full file name, and
+ // log message.
+ Log(severity, full_filename, std::string(message, message_len));
+ }
+
+ // Implements the mock method:
+ //
+ // void Log(LogSeverity severity,
+ // const string& file_path,
+ // const string& message);
+ MOCK_METHOD(void, Log,
+ (LogSeverity severity, const string& file_path,
+ const string& message));
+};
+```
+
+By defining a new mock method with a trimmed argument list, we make the mock
+class more user-friendly.
+
+This technique may also be applied to make overloaded methods more amenable to
+mocking. For example, when overloads have been used to implement default
+arguments:
+
+```cpp
+class MockTurtleFactory : public TurtleFactory {
+ public:
+ Turtle* MakeTurtle(int length, int weight) override { ... }
+ Turtle* MakeTurtle(int length, int weight, int speed) override { ... }
+
+ // the above methods delegate to this one:
+ MOCK_METHOD(Turtle*, DoMakeTurtle, ());
+};
+```
+
+This allows tests that don't care which overload was invoked to avoid specifying
+argument matchers:
+
+```cpp
+ON_CALL(factory, DoMakeTurtle)
+ .WillByDefault(Return(MakeMockTurtle()));
+```
+
+### Alternative to Mocking Concrete Classes
+
+Often you may find yourself using classes that don't implement interfaces. In
+order to test your code that uses such a class (let's call it `Concrete`), you
+may be tempted to make the methods of `Concrete` virtual and then mock it.
+
+Try not to do that.
+
+Making a non-virtual function virtual is a big decision. It creates an extension
+point where subclasses can tweak your class' behavior. This weakens your control
+on the class because now it's harder to maintain the class invariants. You
+should make a function virtual only when there is a valid reason for a subclass
+to override it.
+
+Mocking concrete classes directly is problematic as it creates a tight coupling
+between the class and the tests - any small change in the class may invalidate
+your tests and make test maintenance a pain.
+
+To avoid such problems, many programmers have been practicing "coding to
+interfaces": instead of talking to the `Concrete` class, your code would define
+an interface and talk to it. Then you implement that interface as an adaptor on
+top of `Concrete`. In tests, you can easily mock that interface to observe how
+your code is doing.
+
+This technique incurs some overhead:
+
+* You pay the cost of virtual function calls (usually not a problem).
+* There is more abstraction for the programmers to learn.
+
+However, it can also bring significant benefits in addition to better
+testability:
+
+* `Concrete`'s API may not fit your problem domain very well, as you may not
+ be the only client it tries to serve. By designing your own interface, you
+ have a chance to tailor it to your need - you may add higher-level
+ functionalities, rename stuff, etc instead of just trimming the class. This
+ allows you to write your code (user of the interface) in a more natural way,
+ which means it will be more readable, more maintainable, and you'll be more
+ productive.
+* If `Concrete`'s implementation ever has to change, you don't have to rewrite
+ everywhere it is used. Instead, you can absorb the change in your
+ implementation of the interface, and your other code and tests will be
+ insulated from this change.
+
+Some people worry that if everyone is practicing this technique, they will end
+up writing lots of redundant code. This concern is totally understandable.
+However, there are two reasons why it may not be the case:
+
+* Different projects may need to use `Concrete` in different ways, so the best
+ interfaces for them will be different. Therefore, each of them will have its
+ own domain-specific interface on top of `Concrete`, and they will not be the
+ same code.
+* If enough projects want to use the same interface, they can always share it,
+ just like they have been sharing `Concrete`. You can check in the interface
+ and the adaptor somewhere near `Concrete` (perhaps in a `contrib`
+ sub-directory) and let many projects use it.
+
+You need to weigh the pros and cons carefully for your particular problem, but
+I'd like to assure you that the Java community has been practicing this for a
+long time and it's a proven effective technique applicable in a wide variety of
+situations. :-)
+
+### Delegating Calls to a Fake {#DelegatingToFake}
+
+Some times you have a non-trivial fake implementation of an interface. For
+example:
+
+```cpp
+class Foo {
+ public:
+ virtual ~Foo() {}
+ virtual char DoThis(int n) = 0;
+ virtual void DoThat(const char* s, int* p) = 0;
+};
+
+class FakeFoo : public Foo {
+ public:
+ char DoThis(int n) override {
+ return (n > 0) ? '+' :
+ (n < 0) ? '-' : '0';
+ }
+
+ void DoThat(const char* s, int* p) override {
+ *p = strlen(s);
+ }
+};
+```
+
+Now you want to mock this interface such that you can set expectations on it.
+However, you also want to use `FakeFoo` for the default behavior, as duplicating
+it in the mock object is, well, a lot of work.
+
+When you define the mock class using gMock, you can have it delegate its default
+action to a fake class you already have, using this pattern:
+
+```cpp
+class MockFoo : public Foo {
+ public:
+ // Normal mock method definitions using gMock.
+ MOCK_METHOD(char, DoThis, (int n), (override));
+ MOCK_METHOD(void, DoThat, (const char* s, int* p), (override));
+
+ // Delegates the default actions of the methods to a FakeFoo object.
+ // This must be called *before* the custom ON_CALL() statements.
+ void DelegateToFake() {
+ ON_CALL(*this, DoThis).WillByDefault([this](int n) {
+ return fake_.DoThis(n);
+ });
+ ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
+ fake_.DoThat(s, p);
+ });
+ }
+
+ private:
+ FakeFoo fake_; // Keeps an instance of the fake in the mock.
+};
+```
+
+With that, you can use `MockFoo` in your tests as usual. Just remember that if
+you don't explicitly set an action in an `ON_CALL()` or `EXPECT_CALL()`, the
+fake will be called upon to do it.:
+
+```cpp
+using ::testing::_;
+
+TEST(AbcTest, Xyz) {
+ MockFoo foo;
+
+ foo.DelegateToFake(); // Enables the fake for delegation.
+
+ // Put your ON_CALL(foo, ...)s here, if any.
+
+ // No action specified, meaning to use the default action.
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(foo, DoThat(_, _));
+
+ int n = 0;
+ EXPECT_EQ('+', foo.DoThis(5)); // FakeFoo::DoThis() is invoked.
+ foo.DoThat("Hi", &n); // FakeFoo::DoThat() is invoked.
+ EXPECT_EQ(2, n);
+}
+```
+
+**Some tips:**
+
+* If you want, you can still override the default action by providing your own
+ `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`.
+* In `DelegateToFake()`, you only need to delegate the methods whose fake
+ implementation you intend to use.
+
+* The general technique discussed here works for overloaded methods, but
+ you'll need to tell the compiler which version you mean. To disambiguate a
+ mock function (the one you specify inside the parentheses of `ON_CALL()`),
+ use [this technique](#SelectOverload); to disambiguate a fake function (the
+ one you place inside `Invoke()`), use a `static_cast` to specify the
+ function's type. For instance, if class `Foo` has methods `char DoThis(int
+ n)` and `bool DoThis(double x) const`, and you want to invoke the latter,
+ you need to write `Invoke(&fake_, static_cast<bool (FakeFoo::*)(double)
+ const>(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)`
+ (The strange-looking thing inside the angled brackets of `static_cast` is
+ the type of a function pointer to the second `DoThis()` method.).
+
+* Having to mix a mock and a fake is often a sign of something gone wrong.
+ Perhaps you haven't got used to the interaction-based way of testing yet. Or
+ perhaps your interface is taking on too many roles and should be split up.
+ Therefore, **don't abuse this**. We would only recommend to do it as an
+ intermediate step when you are refactoring your code.
+
+Regarding the tip on mixing a mock and a fake, here's an example on why it may
+be a bad sign: Suppose you have a class `System` for low-level system
+operations. In particular, it does file and I/O operations. And suppose you want
+to test how your code uses `System` to do I/O, and you just want the file
+operations to work normally. If you mock out the entire `System` class, you'll
+have to provide a fake implementation for the file operation part, which
+suggests that `System` is taking on too many roles.
+
+Instead, you can define a `FileOps` interface and an `IOOps` interface and split
+`System`'s functionalities into the two. Then you can mock `IOOps` without
+mocking `FileOps`.
+
+### Delegating Calls to a Real Object
+
+When using testing doubles (mocks, fakes, stubs, and etc), sometimes their
+behaviors will differ from those of the real objects. This difference could be
+either intentional (as in simulating an error such that you can test the error
+handling code) or unintentional. If your mocks have different behaviors than the
+real objects by mistake, you could end up with code that passes the tests but
+fails in production.
+
+You can use the *delegating-to-real* technique to ensure that your mock has the
+same behavior as the real object while retaining the ability to validate calls.
+This technique is very similar to the [delegating-to-fake](#DelegatingToFake)
+technique, the difference being that we use a real object instead of a fake.
+Here's an example:
+
+```cpp
+using ::testing::AtLeast;
+
+class MockFoo : public Foo {
+ public:
+ MockFoo() {
+ // By default, all calls are delegated to the real object.
+ ON_CALL(*this, DoThis).WillByDefault([this](int n) {
+ return real_.DoThis(n);
+ });
+ ON_CALL(*this, DoThat).WillByDefault([this](const char* s, int* p) {
+ real_.DoThat(s, p);
+ });
+ ...
+ }
+ MOCK_METHOD(char, DoThis, ...);
+ MOCK_METHOD(void, DoThat, ...);
+ ...
+ private:
+ Foo real_;
+};
+
+...
+ MockFoo mock;
+ EXPECT_CALL(mock, DoThis())
+ .Times(3);
+ EXPECT_CALL(mock, DoThat("Hi"))
+ .Times(AtLeast(1));
+ ... use mock in test ...
+```
+
+With this, gMock will verify that your code made the right calls (with the right
+arguments, in the right order, called the right number of times, etc), and a
+real object will answer the calls (so the behavior will be the same as in
+production). This gives you the best of both worlds.
+
+### Delegating Calls to a Parent Class
+
+Ideally, you should code to interfaces, whose methods are all pure virtual. In
+reality, sometimes you do need to mock a virtual method that is not pure (i.e,
+it already has an implementation). For example:
+
+```cpp
+class Foo {
+ public:
+ virtual ~Foo();
+
+ virtual void Pure(int n) = 0;
+ virtual int Concrete(const char* str) { ... }
+};
+
+class MockFoo : public Foo {
+ public:
+ // Mocking a pure method.
+ MOCK_METHOD(void, Pure, (int n), (override));
+ // Mocking a concrete method. Foo::Concrete() is shadowed.
+ MOCK_METHOD(int, Concrete, (const char* str), (override));
+};
+```
+
+Sometimes you may want to call `Foo::Concrete()` instead of
+`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub action, or
+perhaps your test doesn't need to mock `Concrete()` at all (but it would be
+oh-so painful to have to define a new mock class whenever you don't need to mock
+one of its methods).
+
+You can call `Foo::Concrete()` inside an action by:
+
+```cpp
+...
+ EXPECT_CALL(foo, Concrete).WillOnce([&foo](const char* str) {
+ return foo.Foo::Concrete(str);
+ });
+```
+
+or tell the mock object that you don't want to mock `Concrete()`:
+
+```cpp
+...
+ ON_CALL(foo, Concrete).WillByDefault([&foo](const char* str) {
+ return foo.Foo::Concrete(str);
+ });
+```
+
+(Why don't we just write `{ return foo.Concrete(str); }`? If you do that,
+`MockFoo::Concrete()` will be called (and cause an infinite recursion) since
+`Foo::Concrete()` is virtual. That's just how C++ works.)
+
+## Using Matchers
+
+### Matching Argument Values Exactly
+
+You can specify exactly which arguments a mock method is expecting:
+
+```cpp
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(5))
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", bar));
+```
+
+### Using Simple Matchers
+
+You can use matchers to match arguments that have a certain property:
+
+```cpp
+using ::testing::NotNull;
+using ::testing::Return;
+...
+ EXPECT_CALL(foo, DoThis(Ge(5))) // The argument must be >= 5.
+ .WillOnce(Return('a'));
+ EXPECT_CALL(foo, DoThat("Hello", NotNull()));
+ // The second argument must not be NULL.
+```
+
+A frequently used matcher is `_`, which matches anything:
+
+```cpp
+ EXPECT_CALL(foo, DoThat(_, NotNull()));
+```
+<!-- GOOGLETEST_CM0022 DO NOT DELETE -->
+
+### Combining Matchers {#CombiningMatchers}
+
+You can build complex matchers from existing ones using `AllOf()`,
+`AllOfArray()`, `AnyOf()`, `AnyOfArray()` and `Not()`:
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::HasSubstr;
+using ::testing::Ne;
+using ::testing::Not;
+...
+ // The argument must be > 5 and != 10.
+ EXPECT_CALL(foo, DoThis(AllOf(Gt(5),
+ Ne(10))));
+
+ // The first argument must not contain sub-string "blah".
+ EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")),
+ NULL));
+```
+
+Matchers are function objects, and parametrized matchers can be composed just
+like any other function. However because their types can be long and rarely
+provide meaningful information, it can be easier to express them with C++14
+generic lambdas to avoid specifying types. For example,
+
+```cpp
+using ::testing::Contains;
+using ::testing::Property;
+
+inline constexpr auto HasFoo = [](const auto& f) {
+ return Property(&MyClass::foo, Contains(f));
+};
+...
+ EXPECT_THAT(x, HasFoo("blah"));
+```
+
+### Casting Matchers {#SafeMatcherCast}
+
+gMock matchers are statically typed, meaning that the compiler can catch your
+mistake if you use a matcher of the wrong type (for example, if you use `Eq(5)`
+to match a `string` argument). Good for you!
+
+Sometimes, however, you know what you're doing and want the compiler to give you
+some slack. One example is that you have a matcher for `long` and the argument
+you want to match is `int`. While the two types aren't exactly the same, there
+is nothing really wrong with using a `Matcher<long>` to match an `int` - after
+all, we can first convert the `int` argument to a `long` losslessly before
+giving it to the matcher.
+
+To support this need, gMock gives you the `SafeMatcherCast<T>(m)` function. It
+casts a matcher `m` to type `Matcher<T>`. To ensure safety, gMock checks that
+(let `U` be the type `m` accepts :
+
+1. Type `T` can be *implicitly* cast to type `U`;
+2. When both `T` and `U` are built-in arithmetic types (`bool`, integers, and
+ floating-point numbers), the conversion from `T` to `U` is not lossy (in
+ other words, any value representable by `T` can also be represented by `U`);
+ and
+3. When `U` is a reference, `T` must also be a reference (as the underlying
+ matcher may be interested in the address of the `U` value).
+
+The code won't compile if any of these conditions isn't met.
+
+Here's one example:
+
+```cpp
+using ::testing::SafeMatcherCast;
+
+// A base class and a child class.
+class Base { ... };
+class Derived : public Base { ... };
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(void, DoThis, (Derived* derived), (override));
+};
+
+...
+ MockFoo foo;
+ // m is a Matcher<Base*> we got from somewhere.
+ EXPECT_CALL(foo, DoThis(SafeMatcherCast<Derived*>(m)));
+```
+
+If you find `SafeMatcherCast<T>(m)` too limiting, you can use a similar function
+`MatcherCast<T>(m)`. The difference is that `MatcherCast` works as long as you
+can `static_cast` type `T` to type `U`.
+
+`MatcherCast` essentially lets you bypass C++'s type system (`static_cast` isn't
+always safe as it could throw away information, for example), so be careful not
+to misuse/abuse it.
+
+### Selecting Between Overloaded Functions {#SelectOverload}
+
+If you expect an overloaded function to be called, the compiler may need some
+help on which overloaded version it is.
+
+To disambiguate functions overloaded on the const-ness of this object, use the
+`Const()` argument wrapper.
+
+```cpp
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+ MOCK_METHOD(const Bar&, GetBar, (), (const, override));
+};
+
+...
+ MockFoo foo;
+ Bar bar1, bar2;
+ EXPECT_CALL(foo, GetBar()) // The non-const GetBar().
+ .WillOnce(ReturnRef(bar1));
+ EXPECT_CALL(Const(foo), GetBar()) // The const GetBar().
+ .WillOnce(ReturnRef(bar2));
+```
+
+(`Const()` is defined by gMock and returns a `const` reference to its argument.)
+
+To disambiguate overloaded functions with the same number of arguments but
+different argument types, you may need to specify the exact type of a matcher,
+either by wrapping your matcher in `Matcher<type>()`, or using a matcher whose
+type is fixed (`TypedEq<type>`, `An<type>()`, etc):
+
+```cpp
+using ::testing::An;
+using ::testing::Matcher;
+using ::testing::TypedEq;
+
+class MockPrinter : public Printer {
+ public:
+ MOCK_METHOD(void, Print, (int n), (override));
+ MOCK_METHOD(void, Print, (char c), (override));
+};
+
+TEST(PrinterTest, Print) {
+ MockPrinter printer;
+
+ EXPECT_CALL(printer, Print(An<int>())); // void Print(int);
+ EXPECT_CALL(printer, Print(Matcher<int>(Lt(5)))); // void Print(int);
+ EXPECT_CALL(printer, Print(TypedEq<char>('a'))); // void Print(char);
+
+ printer.Print(3);
+ printer.Print(6);
+ printer.Print('a');
+}
+```
+
+### Performing Different Actions Based on the Arguments
+
+When a mock method is called, the *last* matching expectation that's still
+active will be selected (think "newer overrides older"). So, you can make a
+method do different things depending on its argument values like this:
+
+```cpp
+using ::testing::_;
+using ::testing::Lt;
+using ::testing::Return;
+...
+ // The default case.
+ EXPECT_CALL(foo, DoThis(_))
+ .WillRepeatedly(Return('b'));
+ // The more specific case.
+ EXPECT_CALL(foo, DoThis(Lt(5)))
+ .WillRepeatedly(Return('a'));
+```
+
+Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will be
+returned; otherwise `'b'` will be returned.
+
+### Matching Multiple Arguments as a Whole
+
+Sometimes it's not enough to match the arguments individually. For example, we
+may want to say that the first argument must be less than the second argument.
+The `With()` clause allows us to match all arguments of a mock function as a
+whole. For example,
+
+```cpp
+using ::testing::_;
+using ::testing::Ne;
+using ::testing::Lt;
+...
+ EXPECT_CALL(foo, InRange(Ne(0), _))
+ .With(Lt());
+```
+
+says that the first argument of `InRange()` must not be 0, and must be less than
+the second argument.
+
+The expression inside `With()` must be a matcher of type `Matcher<std::tuple<A1,
+..., An>>`, where `A1`, ..., `An` are the types of the function arguments.
+
+You can also write `AllArgs(m)` instead of `m` inside `.With()`. The two forms
+are equivalent, but `.With(AllArgs(Lt()))` is more readable than `.With(Lt())`.
+
+You can use `Args<k1, ..., kn>(m)` to match the `n` selected arguments (as a
+tuple) against `m`. For example,
+
+```cpp
+using ::testing::_;
+using ::testing::AllOf;
+using ::testing::Args;
+using ::testing::Lt;
+...
+ EXPECT_CALL(foo, Blah)
+ .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt())));
+```
+
+says that `Blah` will be called with arguments `x`, `y`, and `z` where `x < y <
+z`. Note that in this example, it wasn't necessary specify the positional
+matchers.
+
+As a convenience and example, gMock provides some matchers for 2-tuples,
+including the `Lt()` matcher above. See [here](#MultiArgMatchers) for the
+complete list.
+
+Note that if you want to pass the arguments to a predicate of your own (e.g.
+`.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be written to
+take a `std::tuple` as its argument; gMock will pass the `n` selected arguments
+as *one* single tuple to the predicate.
+
+### Using Matchers as Predicates
+
+Have you noticed that a matcher is just a fancy predicate that also knows how to
+describe itself? Many existing algorithms take predicates as arguments (e.g.
+those defined in STL's `<algorithm>` header), and it would be a shame if gMock
+matchers were not allowed to participate.
+
+Luckily, you can use a matcher where a unary predicate functor is expected by
+wrapping it inside the `Matches()` function. For example,
+
+```cpp
+#include <algorithm>
+#include <vector>
+
+using ::testing::Matches;
+using ::testing::Ge;
+
+vector<int> v;
+...
+// How many elements in v are >= 10?
+const int count = count_if(v.begin(), v.end(), Matches(Ge(10)));
+```
+
+Since you can build complex matchers from simpler ones easily using gMock, this
+gives you a way to conveniently construct composite predicates (doing the same
+using STL's `<functional>` header is just painful). For example, here's a
+predicate that's satisfied by any number that is >= 0, <= 100, and != 50:
+
+```cpp
+using testing::AllOf;
+using testing::Ge;
+using testing::Le;
+using testing::Matches;
+using testing::Ne;
+...
+Matches(AllOf(Ge(0), Le(100), Ne(50)))
+```
+
+### Using Matchers in googletest Assertions
+
+Since matchers are basically predicates that also know how to describe
+themselves, there is a way to take advantage of them in googletest assertions.
+It's called `ASSERT_THAT` and `EXPECT_THAT`:
+
+```cpp
+ ASSERT_THAT(value, matcher); // Asserts that value matches matcher.
+ EXPECT_THAT(value, matcher); // The non-fatal version.
+```
+
+For example, in a googletest test you can write:
+
+```cpp
+#include "gmock/gmock.h"
+
+using ::testing::AllOf;
+using ::testing::Ge;
+using ::testing::Le;
+using ::testing::MatchesRegex;
+using ::testing::StartsWith;
+
+...
+ EXPECT_THAT(Foo(), StartsWith("Hello"));
+ EXPECT_THAT(Bar(), MatchesRegex("Line \\d+"));
+ ASSERT_THAT(Baz(), AllOf(Ge(5), Le(10)));
+```
+
+which (as you can probably guess) executes `Foo()`, `Bar()`, and `Baz()`, and
+verifies that:
+
+* `Foo()` returns a string that starts with `"Hello"`.
+* `Bar()` returns a string that matches regular expression `"Line \\d+"`.
+* `Baz()` returns a number in the range [5, 10].
+
+The nice thing about these macros is that *they read like English*. They
+generate informative messages too. For example, if the first `EXPECT_THAT()`
+above fails, the message will be something like:
+
+```cpp
+Value of: Foo()
+ Actual: "Hi, world!"
+Expected: starts with "Hello"
+```
+
+**Credit:** The idea of `(ASSERT|EXPECT)_THAT` was borrowed from Joe Walnes'
+Hamcrest project, which adds `assertThat()` to JUnit.
+
+### Using Predicates as Matchers
+
+gMock provides a [built-in set](cheat_sheet.md#MatcherList) of matchers. In case
+you find them lacking, you can use an arbitrary unary predicate function or
+functor as a matcher - as long as the predicate accepts a value of the type you
+want. You do this by wrapping the predicate inside the `Truly()` function, for
+example:
+
+```cpp
+using ::testing::Truly;
+
+int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; }
+...
+ // Bar() must be called with an even number.
+ EXPECT_CALL(foo, Bar(Truly(IsEven)));
+```
+
+Note that the predicate function / functor doesn't have to return `bool`. It
+works as long as the return value can be used as the condition in in statement
+`if (condition) ...`.

+
+### Matching Arguments that Are Not Copyable
+
+When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, gMock saves away a copy of
+`bar`. When `Foo()` is called later, gMock compares the argument to `Foo()` with
+the saved copy of `bar`. This way, you don't need to worry about `bar` being
+modified or destroyed after the `EXPECT_CALL()` is executed. The same is true
+when you use matchers like `Eq(bar)`, `Le(bar)`, and so on.
+
+But what if `bar` cannot be copied (i.e. has no copy constructor)? You could
+define your own matcher function or callback and use it with `Truly()`, as the
+previous couple of recipes have shown. Or, you may be able to get away from it
+if you can guarantee that `bar` won't be changed after the `EXPECT_CALL()` is
+executed. Just tell gMock that it should save a reference to `bar`, instead of a
+copy of it. Here's how:
+
+```cpp
+using ::testing::Eq;
+using ::testing::Lt;
+...
+ // Expects that Foo()'s argument == bar.
+ EXPECT_CALL(mock_obj, Foo(Eq(std::ref(bar))));
+
+ // Expects that Foo()'s argument < bar.
+ EXPECT_CALL(mock_obj, Foo(Lt(std::ref(bar))));
+```
+
+Remember: if you do this, don't change `bar` after the `EXPECT_CALL()`, or the
+result is undefined.
+
+### Validating a Member of an Object
+
+Often a mock function takes a reference to object as an argument. When matching
+the argument, you may not want to compare the entire object against a fixed
+object, as that may be over-specification. Instead, you may need to validate a
+certain member variable or the result of a certain getter method of the object.
+You can do this with `Field()` and `Property()`. More specifically,
+
+```cpp
+Field(&Foo::bar, m)
+```
+
+is a matcher that matches a `Foo` object whose `bar` member variable satisfies
+matcher `m`.
+
+```cpp
+Property(&Foo::baz, m)
+```
+
+is a matcher that matches a `Foo` object whose `baz()` method returns a value
+that satisfies matcher `m`.
+
+For example:
+
+<!-- mdformat off(github rendering does not support multiline tables) -->
+| Expression | Description |
+| :--------------------------- | :--------------------------------------- |
+| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`. |
+| `Property(&Foo::name, StartsWith("John "))` | Matches `x` where `x.name()` starts with `"John "`. |
+<!-- mdformat on -->
+
+Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no argument
+and be declared as `const`.
+
+BTW, `Field()` and `Property()` can also match plain pointers to objects. For
+instance,
+
+```cpp
+using ::testing::Field;
+using ::testing::Ge;
+...
+Field(&Foo::number, Ge(3))
+```
+
+matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`, the match
+will always fail regardless of the inner matcher.
+
+What if you want to validate more than one members at the same time? Remember
+that there are [`AllOf()` and `AllOfArray()`](#CombiningMatchers).
+
+Finally `Field()` and `Property()` provide overloads that take the field or
+property names as the first argument to include it in the error message. This
+can be useful when creating combined matchers.
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Field;
+using ::testing::Matcher;
+using ::testing::SafeMatcherCast;
+
+Matcher<Foo> IsFoo(const Foo& foo) {
+ return AllOf(Field("some_field", &Foo::some_field, foo.some_field),
+ Field("other_field", &Foo::other_field, foo.other_field),
+ Field("last_field", &Foo::last_field, foo.last_field));
+}
+```
+
+### Validating the Value Pointed to by a Pointer Argument
+
+C++ functions often take pointers as arguments. You can use matchers like
+`IsNull()`, `NotNull()`, and other comparison matchers to match a pointer, but
+what if you want to make sure the value *pointed to* by the pointer, instead of
+the pointer itself, has a certain property? Well, you can use the `Pointee(m)`
+matcher.
+
+`Pointee(m)` matches a pointer if and only if `m` matches the value the pointer
+points to. For example:
+
+```cpp
+using ::testing::Ge;
+using ::testing::Pointee;
+...
+ EXPECT_CALL(foo, Bar(Pointee(Ge(3))));
+```
+
+expects `foo.Bar()` to be called with a pointer that points to a value greater
+than or equal to 3.
+
+One nice thing about `Pointee()` is that it treats a `NULL` pointer as a match
+failure, so you can write `Pointee(m)` instead of
+
+```cpp
+using ::testing::AllOf;
+using ::testing::NotNull;
+using ::testing::Pointee;
+...
+ AllOf(NotNull(), Pointee(m))
+```
+
+without worrying that a `NULL` pointer will crash your test.
+
+Also, did we tell you that `Pointee()` works with both raw pointers **and**
+smart pointers (`std::unique_ptr`, `std::shared_ptr`, etc)?
+
+What if you have a pointer to pointer? You guessed it - you can use nested
+`Pointee()` to probe deeper inside the value. For example,
+`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer that points
+to a number less than 3 (what a mouthful...).
+
+### Testing a Certain Property of an Object
+
+Sometimes you want to specify that an object argument has a certain property,
+but there is no existing matcher that does this. If you want good error
+messages, you should [define a matcher](#NewMatchers). If you want to do it
+quick and dirty, you could get away with writing an ordinary function.
+
+Let's say you have a mock function that takes an object of type `Foo`, which has
+an `int bar()` method and an `int baz()` method, and you want to constrain that
+the argument's `bar()` value plus its `baz()` value is a given number. Here's
+how you can define a matcher to do it:
+
+```cpp
+using ::testing::Matcher;
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+
+class BarPlusBazEqMatcher : public MatcherInterface<const Foo&> {
+ public:
+ explicit BarPlusBazEqMatcher(int expected_sum)
+ : expected_sum_(expected_sum) {}
+
+ bool MatchAndExplain(const Foo& foo,
+ MatchResultListener* /* listener */) const override {
+ return (foo.bar() + foo.baz()) == expected_sum_;
+ }
+
+ void DescribeTo(std::ostream* os) const override {
+ *os << "bar() + baz() equals " << expected_sum_;
+ }
+
+ void DescribeNegationTo(std::ostream* os) const override {
+ *os << "bar() + baz() does not equal " << expected_sum_;
+ }
+ private:
+ const int expected_sum_;
+};
+
+Matcher<const Foo&> BarPlusBazEq(int expected_sum) {
+ return MakeMatcher(new BarPlusBazEqMatcher(expected_sum));
+}
+
+...
+ EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...;
+```
+
+### Matching Containers
+
+Sometimes an STL container (e.g. list, vector, map, ...) is passed to a mock
+function and you may want to validate it. Since most STL containers support the
+`==` operator, you can write `Eq(expected_container)` or simply
+`expected_container` to match a container exactly.
+
+Sometimes, though, you may want to be more flexible (for example, the first
+element must be an exact match, but the second element can be any positive
+number, and so on). Also, containers used in tests often have a small number of
+elements, and having to define the expected container out-of-line is a bit of a
+hassle.
+
+You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in such
+cases:
+
+```cpp
+using ::testing::_;
+using ::testing::ElementsAre;
+using ::testing::Gt;
+...
+ MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
+...
+ EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5)));
+```
+
+The above matcher says that the container must have 4 elements, which must be 1,
+greater than 0, anything, and 5 respectively.
+
+If you instead write:
+
+```cpp
+using ::testing::_;
+using ::testing::Gt;
+using ::testing::UnorderedElementsAre;
+...
+ MOCK_METHOD(void, Foo, (const vector<int>& numbers), (override));
+...
+ EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5)));
+```
+
+It means that the container must have 4 elements, which (under some permutation)
+must be 1, greater than 0, anything, and 5 respectively.
+
+As an alternative you can place the arguments in a C-style array and use
+`ElementsAreArray()` or `UnorderedElementsAreArray()` instead:
+
+```cpp
+using ::testing::ElementsAreArray;
+...
+ // ElementsAreArray accepts an array of element values.
+ const int expected_vector1[] = {1, 5, 2, 4, ...};
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1)));
+
+ // Or, an array of element matchers.
+ Matcher<int> expected_vector2[] = {1, Gt(2), _, 3, ...};
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2)));
+```
+
+In case the array needs to be dynamically created (and therefore the array size
+cannot be inferred by the compiler), you can give `ElementsAreArray()` an
+additional argument to specify the array size:
+
+```cpp
+using ::testing::ElementsAreArray;
+...
+ int* const expected_vector3 = new int[count];
+ ... fill expected_vector3 with values ...
+ EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count)));
+```
+
+Use `Pair` when comparing maps or other associative containers.
+
+```cpp
+using testing::ElementsAre;
+using testing::Pair;
+...
+ std::map<string, int> m = {{"a", 1}, {"b", 2}, {"c", 3}};
+ EXPECT_THAT(m, ElementsAre(Pair("a", 1), Pair("b", 2), Pair("c", 3)));
+```
+
+**Tips:**
+
+* `ElementsAre*()` can be used to match *any* container that implements the
+ STL iterator pattern (i.e. it has a `const_iterator` type and supports
+ `begin()/end()`), not just the ones defined in STL. It will even work with
+ container types yet to be written - as long as they follows the above
+ pattern.
+* You can use nested `ElementsAre*()` to match nested (multi-dimensional)
+ containers.
+* If the container is passed by pointer instead of by reference, just write
+ `Pointee(ElementsAre*(...))`.
+* The order of elements *matters* for `ElementsAre*()`. If you are using it
+ with containers whose element order are undefined (e.g. `hash_map`) you
+ should use `WhenSorted` around `ElementsAre`.
+
+### Sharing Matchers
+
+Under the hood, a gMock matcher object consists of a pointer to a ref-counted
+implementation object. Copying matchers is allowed and very efficient, as only
+the pointer is copied. When the last matcher that references the implementation
+object dies, the implementation object will be deleted.
+
+Therefore, if you have some complex matcher that you want to use again and
+again, there is no need to build it everytime. Just assign it to a matcher
+variable and use that variable repeatedly! For example,
+
+```cpp
+using ::testing::AllOf;
+using ::testing::Gt;
+using ::testing::Le;
+using ::testing::Matcher;
+...
+ Matcher<int> in_range = AllOf(Gt(5), Le(10));
+ ... use in_range as a matcher in multiple EXPECT_CALLs ...
+```
+
+### Matchers must have no side-effects {#PureMatchers}
+
+WARNING: gMock does not guarantee when or how many times a matcher will be
+invoked. Therefore, all matchers must be *purely functional*: they cannot have
+any side effects, and the match result must not depend on anything other than
+the matcher's parameters and the value being matched.
+
+This requirement must be satisfied no matter how a matcher is defined (e.g., if
+it is one of the standard matchers, or a custom matcher). In particular, a
+matcher can never call a mock function, as that will affect the state of the
+mock object and gMock.
+
+## Setting Expectations
+
+### Knowing When to Expect {#UseOnCall}
+
+<!-- GOOGLETEST_CM0018 DO NOT DELETE -->
+
+**`ON_CALL`** is likely the *single most under-utilized construct* in gMock.
+
+There are basically two constructs for defining the behavior of a mock object:
+`ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when
+a mock method is called, but <em>doesn't imply any expectation on the method
+being called</em>. `EXPECT_CALL` not only defines the behavior, but also sets an
+expectation that <em>the method will be called with the given arguments, for the
+given number of times</em> (and *in the given order* when you specify the order
+too).
+
+Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every
+`EXPECT_CALL` adds a constraint on the behavior of the code under test. Having
+more constraints than necessary is *baaad* - even worse than not having enough
+constraints.
+
+This may be counter-intuitive. How could tests that verify more be worse than
+tests that verify less? Isn't verification the whole point of tests?
+
+The answer lies in *what* a test should verify. **A good test verifies the
+contract of the code.** If a test over-specifies, it doesn't leave enough
+freedom to the implementation. As a result, changing the implementation without
+breaking the contract (e.g. refactoring and optimization), which should be
+perfectly fine to do, can break such tests. Then you have to spend time fixing
+them, only to see them broken again the next time the implementation is changed.
+
+Keep in mind that one doesn't have to verify more than one property in one test.
+In fact, **it's a good style to verify only one thing in one test.** If you do
+that, a bug will likely break only one or two tests instead of dozens (which
+case would you rather debug?). If you are also in the habit of giving tests
+descriptive names that tell what they verify, you can often easily guess what's
+wrong just from the test log itself.
+
+So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend
+to verify that the call is made. For example, you may have a bunch of `ON_CALL`s
+in your test fixture to set the common mock behavior shared by all tests in the
+same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s
+to verify different aspects of the code's behavior. Compared with the style
+where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more
+resilient to implementational changes (and thus less likely to require
+maintenance) and makes the intent of the tests more obvious (so they are easier
+to maintain when you do need to maintain them).
+
+If you are bothered by the "Uninteresting mock function call" message printed
+when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock`
+instead to suppress all such messages for the mock object, or suppress the
+message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO
+NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test
+that's a pain to maintain.
+
+### Ignoring Uninteresting Calls
+
+If you are not interested in how a mock method is called, just don't say
+anything about it. In this case, if the method is ever called, gMock will
+perform its default action to allow the test program to continue. If you are not
+happy with the default action taken by gMock, you can override it using
+`DefaultValue<T>::Set()` (described [here](#DefaultValue)) or `ON_CALL()`.
+
+Please note that once you expressed interest in a particular mock method (via
+`EXPECT_CALL()`), all invocations to it must match some expectation. If this
+function is called but the arguments don't match any `EXPECT_CALL()` statement,
+it will be an error.
+
+### Disallowing Unexpected Calls
+
+If a mock method shouldn't be called at all, explicitly say so:
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+If some calls to the method are allowed, but the rest are not, just list all the
+expected calls:
+
+```cpp
+using ::testing::AnyNumber;
+using ::testing::Gt;
+...
+ EXPECT_CALL(foo, Bar(5));
+ EXPECT_CALL(foo, Bar(Gt(10)))
+ .Times(AnyNumber());
+```
+
+A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()` statements
+will be an error.
+
+### Understanding Uninteresting vs Unexpected Calls {#uninteresting-vs-unexpected}
+
+*Uninteresting* calls and *unexpected* calls are different concepts in gMock.
+*Very* different.
+
+A call `x.Y(...)` is **uninteresting** if there's *not even a single*
+`EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the
+`x.Y()` method at all, as evident in that the test doesn't care to say anything
+about it.
+
+A call `x.Y(...)` is **unexpected** if there are *some* `EXPECT_CALL(x,
+Y(...))`s set, but none of them matches the call. Put another way, the test is
+interested in the `x.Y()` method (therefore it explicitly sets some
+`EXPECT_CALL` to verify how it's called); however, the verification fails as the
+test doesn't expect this particular call to happen.
+
+**An unexpected call is always an error,** as the code under test doesn't behave
+the way the test expects it to behave.
+
+**By default, an uninteresting call is not an error,** as it violates no
+constraint specified by the test. (gMock's philosophy is that saying nothing
+means there is no constraint.) However, it leads to a warning, as it *might*
+indicate a problem (e.g. the test author might have forgotten to specify a
+constraint).
+
+In gMock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or
+"strict". How does this affect uninteresting calls and unexpected calls?
+
+A **nice mock** suppresses uninteresting call *warnings*. It is less chatty than
+the default mock, but otherwise is the same. If a test fails with a default
+mock, it will also fail using a nice mock instead. And vice versa. Don't expect
+making a mock nice to change the test's result.
+
+A **strict mock** turns uninteresting call warnings into errors. So making a
+mock strict may change the test's result.
+
+Let's look at an example:
+
+```cpp
+TEST(...) {
+ NiceMock<MockDomainRegistry> mock_registry;
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+
+ // Use mock_registry in code under test.
+ ... &mock_registry ...
+}
+```
+
+The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have
+`"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it
+will be an unexpected call, and thus an error. *Having a nice mock doesn't
+change the severity of an unexpected call.*
+
+So how do we tell gMock that `GetDomainOwner()` can be called with some other
+arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`:
+
+```cpp
+ EXPECT_CALL(mock_registry, GetDomainOwner(_))
+ .Times(AnyNumber()); // catches all other calls to this method.
+ EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
+ .WillRepeatedly(Return("Larry Page"));
+```
+
+Remember that `_` is the wildcard matcher that matches anything. With this, if
+`GetDomainOwner("google.com")` is called, it will do what the second
+`EXPECT_CALL` says; if it is called with a different argument, it will do what
+the first `EXPECT_CALL` says.
+
+Note that the order of the two `EXPECT_CALL`s is important, as a newer
+`EXPECT_CALL` takes precedence over an older one.
+
+For more on uninteresting calls, nice mocks, and strict mocks, read
+["The Nice, the Strict, and the Naggy"](#NiceStrictNaggy).
+
+### Ignoring Uninteresting Arguments {#ParameterlessExpectations}
+
+If your test doesn't care about the parameters (it only cares about the number
+or order of calls), you can often simply omit the parameter list:
+
+```cpp
+ // Expect foo.Bar( ... ) twice with any arguments.
+ EXPECT_CALL(foo, Bar).Times(2);
+
+ // Delegate to the given method whenever the factory is invoked.
+ ON_CALL(foo_factory, MakeFoo)
+ .WillByDefault(&BuildFooForTest);
+```
+
+This functionality is only available when a method is not overloaded; to prevent
+unexpected behavior it is a compilation error to try to set an expectation on a
+method where the specific overload is ambiguous. You can work around this by
+supplying a [simpler mock interface](#SimplerInterfaces) than the mocked class
+provides.
+
+This pattern is also useful when the arguments are interesting, but match logic
+is substantially complex. You can leave the argument list unspecified and use
+SaveArg actions to [save the values for later verification](#SaveArgVerify). If
+you do that, you can easily differentiate calling the method the wrong number of
+times from calling it with the wrong arguments.
+
+### Expecting Ordered Calls {#OrderedCalls}
+
+Although an `EXPECT_CALL()` statement defined later takes precedence when gMock
+tries to match a function call with an expectation, by default calls don't have
+to happen in the order `EXPECT_CALL()` statements are written. For example, if
+the arguments match the matchers in the second `EXPECT_CALL()`, but not those in
+the first and third, then the second expectation will be used.
+
+If you would rather have all calls occur in the order of the expectations, put
+the `EXPECT_CALL()` statements in a block where you define a variable of type
+`InSequence`:
+
+```cpp
+using ::testing::_;
+using ::testing::InSequence;
+
+ {
+ InSequence s;
+
+ EXPECT_CALL(foo, DoThis(5));
+ EXPECT_CALL(bar, DoThat(_))
+ .Times(2);
+ EXPECT_CALL(foo, DoThis(6));
+ }
+```
+
+In this example, we expect a call to `foo.DoThis(5)`, followed by two calls to
+`bar.DoThat()` where the argument can be anything, which are in turn followed by
+a call to `foo.DoThis(6)`. If a call occurred out-of-order, gMock will report an
+error.
+
+### Expecting Partially Ordered Calls {#PartialOrder}
+
+Sometimes requiring everything to occur in a predetermined order can lead to
+brittle tests. For example, we may care about `A` occurring before both `B` and
+`C`, but aren't interested in the relative order of `B` and `C`. In this case,
+the test should reflect our real intent, instead of being overly constraining.
+
+gMock allows you to impose an arbitrary DAG (directed acyclic graph) on the
+calls. One way to express the DAG is to use the
+[After](cheat_sheet.md#AfterClause) clause of `EXPECT_CALL`.
+
+Another way is via the `InSequence()` clause (not the same as the `InSequence`
+class), which we borrowed from jMock 2. It's less flexible than `After()`, but
+more convenient when you have long chains of sequential calls, as it doesn't
+require you to come up with different names for the expectations in the chains.
+Here's how it works:
+
+If we view `EXPECT_CALL()` statements as nodes in a graph, and add an edge from
+node A to node B wherever A must occur before B, we can get a DAG. We use the
+term "sequence" to mean a directed path in this DAG. Now, if we decompose the
+DAG into sequences, we just need to know which sequences each `EXPECT_CALL()`
+belongs to in order to be able to reconstruct the original DAG.
+
+So, to specify the partial order on the expectations we need to do two things:
+first to define some `Sequence` objects, and then for each `EXPECT_CALL()` say
+which `Sequence` objects it is part of.
+
+Expectations in the same sequence must occur in the order they are written. For
+example,
+
+```cpp
+using ::testing::Sequence;
+...
+ Sequence s1, s2;
+
+ EXPECT_CALL(foo, A())
+ .InSequence(s1, s2);
+ EXPECT_CALL(bar, B())
+ .InSequence(s1);
+ EXPECT_CALL(bar, C())
+ .InSequence(s2);
+ EXPECT_CALL(foo, D())
+ .InSequence(s2);
+```
+
+specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A -> C -> D`):
+
+```text
+ +---> B
+ |
+ A ---|
+ |
+ +---> C ---> D
+```
+
+This means that A must occur before B and C, and C must occur before D. There's
+no restriction about the order other than these.
+
+### Controlling When an Expectation Retires
+
+When a mock method is called, gMock only considers expectations that are still
+active. An expectation is active when created, and becomes inactive (aka
+*retires*) when a call that has to occur later has occurred. For example, in
+
+```cpp
+using ::testing::_;
+using ::testing::Sequence;
+...
+ Sequence s1, s2;
+
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #1
+ .Times(AnyNumber())
+ .InSequence(s1, s2);
+ EXPECT_CALL(log, Log(WARNING, _, "Data set is empty.")) // #2
+ .InSequence(s1);
+ EXPECT_CALL(log, Log(WARNING, _, "User not found.")) // #3
+ .InSequence(s2);
+```
+
+as soon as either #2 or #3 is matched, #1 will retire. If a warning `"File too
+large."` is logged after this, it will be an error.
+
+Note that an expectation doesn't retire automatically when it's saturated. For
+example,
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")); // #2
+```
+
+says that there will be exactly one warning with the message `"File too
+large."`. If the second warning contains this message too, #2 will match again
+and result in an upper-bound-violated error.
+
+If this is not what you want, you can ask an expectation to retire as soon as it
+becomes saturated:
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(log, Log(WARNING, _, _)); // #1
+ EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #2
+ .RetiresOnSaturation();
+```
+
+Here #2 can be used only once, so if you have two warnings with the message
+`"File too large."`, the first will match #2 and the second will match #1 -
+there will be no error.
+
+## Using Actions
+
+### Returning References from Mock Methods
+
+If a mock function's return type is a reference, you need to use `ReturnRef()`
+instead of `Return()` to return a result:
+
+```cpp
+using ::testing::ReturnRef;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(Bar&, GetBar, (), (override));
+};
+...
+ MockFoo foo;
+ Bar bar;
+ EXPECT_CALL(foo, GetBar())
+ .WillOnce(ReturnRef(bar));
+...
+```
+
+### Returning Live Values from Mock Methods
+
+The `Return(x)` action saves a copy of `x` when the action is created, and
+always returns the same value whenever it's executed. Sometimes you may want to
+instead return the *live* value of `x` (i.e. its value at the time when the
+action is *executed*.). Use either `ReturnRef()` or `ReturnPointee()` for this
+purpose.
+
+If the mock function's return type is a reference, you can do it using
+`ReturnRef(x)`, as shown in the previous recipe ("Returning References from Mock
+Methods"). However, gMock doesn't let you use `ReturnRef()` in a mock function
+whose return type is not a reference, as doing that usually indicates a user
+error. So, what shall you do?
+
+Though you may be tempted, DO NOT use `std::ref()`:
+
+```cpp
+using testing::Return;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, GetValue, (), (override));
+};
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(Return(std::ref(x))); // Wrong!
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue());
+```
+
+Unfortunately, it doesn't work here. The above code will fail with error:
+
+```text
+Value of: foo.GetValue()
+ Actual: 0
+Expected: 42
+```
+
+The reason is that `Return(*value*)` converts `value` to the actual return type
+of the mock function at the time when the action is *created*, not when it is
+*executed*. (This behavior was chosen for the action to be safe when `value` is
+a proxy object that references some temporary objects.) As a result,
+`std::ref(x)` is converted to an `int` value (instead of a `const int&`) when
+the expectation is set, and `Return(std::ref(x))` will always return 0.
+
+`ReturnPointee(pointer)` was provided to solve this problem specifically. It
+returns the value pointed to by `pointer` at the time the action is *executed*:
+
+```cpp
+using testing::ReturnPointee;
+...
+ int x = 0;
+ MockFoo foo;
+ EXPECT_CALL(foo, GetValue())
+ .WillRepeatedly(ReturnPointee(&x)); // Note the & here.
+ x = 42;
+ EXPECT_EQ(42, foo.GetValue()); // This will succeed now.
+```
+
+### Combining Actions
+
+Want to do more than one thing when a function is called? That's fine. `DoAll()`
+allow you to do sequence of actions every time. Only the return value of the
+last action in the sequence will be used.
+
+```cpp
+using ::testing::_;
+using ::testing::DoAll;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, Bar, (int n), (override));
+};
+...
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(DoAll(action_1,
+ action_2,
+ ...
+ action_n));
+```
+
+### Verifying Complex Arguments {#SaveArgVerify}
+
+If you want to verify that a method is called with a particular argument but the
+match criteria is complex, it can be difficult to distinguish between
+cardinality failures (calling the method the wrong number of times) and argument
+match failures. Similarly, if you are matching multiple parameters, it may not
+be easy to distinguishing which argument failed to match. For example:
+
+```cpp
+ // Not ideal: this could fail because of a problem with arg1 or arg2, or maybe
+ // just the method wasn't called.
+ EXPECT_CALL(foo, SendValues(_, ElementsAre(1, 4, 4, 7), EqualsProto( ... )));
+```
+
+You can instead save the arguments and test them individually:
+
+```cpp
+ EXPECT_CALL(foo, SendValues)
+ .WillOnce(DoAll(SaveArg<1>(&actual_array), SaveArg<2>(&actual_proto)));
+ ... run the test
+ EXPECT_THAT(actual_array, ElementsAre(1, 4, 4, 7));
+ EXPECT_THAT(actual_proto, EqualsProto( ... ));
+```
+
+### Mocking Side Effects {#MockingSideEffects}
+
+Sometimes a method exhibits its effect not via returning a value but via side
+effects. For example, it may change some global state or modify an output
+argument. To mock side effects, in general you can define your own action by
+implementing `::testing::ActionInterface`.
+
+If all you need to do is to change an output argument, the built-in
+`SetArgPointee()` action is convenient:
+
+```cpp
+using ::testing::_;
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ MOCK_METHOD(void, Mutate, (bool mutate, int* value), (override));
+ ...
+}
+...
+ MockMutator mutator;
+ EXPECT_CALL(mutator, Mutate(true, _))
+ .WillOnce(SetArgPointee<1>(5));
+```
+
+In this example, when `mutator.Mutate()` is called, we will assign 5 to the
+`int` variable pointed to by argument #1 (0-based).
+
+`SetArgPointee()` conveniently makes an internal copy of the value you pass to
+it, removing the need to keep the value in scope and alive. The implication
+however is that the value must have a copy constructor and assignment operator.
+
+If the mock method also needs to return a value as well, you can chain
+`SetArgPointee()` with `Return()` using `DoAll()`, remembering to put the
+`Return()` statement last:
+
+```cpp
+using ::testing::_;
+using ::testing::Return;
+using ::testing::SetArgPointee;
+
+class MockMutator : public Mutator {
+ public:
+ ...
+ MOCK_METHOD(bool, MutateInt, (int* value), (override));
+}
+...
+ MockMutator mutator;
+ EXPECT_CALL(mutator, MutateInt(_))
+ .WillOnce(DoAll(SetArgPointee<0>(5),
+ Return(true)));
+```
+
+Note, however, that if you use the `ReturnOKWith()` method, it will override the
+values provided by `SetArgPointee()` in the response parameters of your function
+call.
+
+If the output argument is an array, use the `SetArrayArgument<N>(first, last)`
+action instead. It copies the elements in source range `[first, last)` to the
+array pointed to by the `N`-th (0-based) argument:
+
+```cpp
+using ::testing::NotNull;
+using ::testing::SetArrayArgument;
+
+class MockArrayMutator : public ArrayMutator {
+ public:
+ MOCK_METHOD(void, Mutate, (int* values, int num_values), (override));
+ ...
+}
+...
+ MockArrayMutator mutator;
+ int values[5] = {1, 2, 3, 4, 5};
+ EXPECT_CALL(mutator, Mutate(NotNull(), 5))
+ .WillOnce(SetArrayArgument<0>(values, values + 5));
+```
+
+This also works when the argument is an output iterator:
+
+```cpp
+using ::testing::_;
+using ::testing::SetArrayArgument;
+
+class MockRolodex : public Rolodex {
+ public:
+ MOCK_METHOD(void, GetNames, (std::back_insert_iterator<vector<string>>),
+ (override));
+ ...
+}
+...
+ MockRolodex rolodex;
+ vector<string> names;
+ names.push_back("George");
+ names.push_back("John");
+ names.push_back("Thomas");
+ EXPECT_CALL(rolodex, GetNames(_))
+ .WillOnce(SetArrayArgument<0>(names.begin(), names.end()));
+```
+
+### Changing a Mock Object's Behavior Based on the State
+
+If you expect a call to change the behavior of a mock object, you can use
+`::testing::InSequence` to specify different behaviors before and after the
+call:
+
+```cpp
+using ::testing::InSequence;
+using ::testing::Return;
+
+...
+ {
+ InSequence seq;
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(true));
+ EXPECT_CALL(my_mock, Flush());
+ EXPECT_CALL(my_mock, IsDirty())
+ .WillRepeatedly(Return(false));
+ }
+ my_mock.FlushIfDirty();
+```
+
+This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called
+and return `false` afterwards.
+
+If the behavior change is more complex, you can store the effects in a variable
+and make a mock method get its return value from that variable:
+
+```cpp
+using ::testing::_;
+using ::testing::SaveArg;
+using ::testing::Return;
+
+ACTION_P(ReturnPointee, p) { return *p; }
+...
+ int previous_value = 0;
+ EXPECT_CALL(my_mock, GetPrevValue)
+ .WillRepeatedly(ReturnPointee(&previous_value));
+ EXPECT_CALL(my_mock, UpdateValue)
+ .WillRepeatedly(SaveArg<0>(&previous_value));
+ my_mock.DoSomethingToUpdateValue();
+```
+
+Here `my_mock.GetPrevValue()` will always return the argument of the last
+`UpdateValue()` call.
+
+### Setting the Default Value for a Return Type {#DefaultValue}
+
+If a mock method's return type is a built-in C++ type or pointer, by default it
+will return 0 when invoked. Also, in C++ 11 and above, a mock method whose
+return type has a default constructor will return a default-constructed value by
+default. You only need to specify an action if this default value doesn't work
+for you.
+
+Sometimes, you may want to change this default value, or you may want to specify
+a default value for types gMock doesn't know about. You can do this using the
+`::testing::DefaultValue` class template:
+
+```cpp
+using ::testing::DefaultValue;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(Bar, CalculateBar, (), (override));
+};
+
+
+...
+ Bar default_bar;
+ // Sets the default return value for type Bar.
+ DefaultValue<Bar>::Set(default_bar);
+
+ MockFoo foo;
+
+ // We don't need to specify an action here, as the default
+ // return value works for us.
+ EXPECT_CALL(foo, CalculateBar());
+
+ foo.CalculateBar(); // This should return default_bar.
+
+ // Unsets the default return value.
+ DefaultValue<Bar>::Clear();
+```
+
+Please note that changing the default value for a type can make your tests hard
+to understand. We recommend you to use this feature judiciously. For example,
+you may want to make sure the `Set()` and `Clear()` calls are right next to the
+code that uses your mock.
+
+### Setting the Default Actions for a Mock Method
+
+You've learned how to change the default value of a given type. However, this
+may be too coarse for your purpose: perhaps you have two mock methods with the
+same return type and you want them to have different behaviors. The `ON_CALL()`
+macro allows you to customize your mock's behavior at the method level:
+
+```cpp
+using ::testing::_;
+using ::testing::AnyNumber;
+using ::testing::Gt;
+using ::testing::Return;
+...
+ ON_CALL(foo, Sign(_))
+ .WillByDefault(Return(-1));
+ ON_CALL(foo, Sign(0))
+ .WillByDefault(Return(0));
+ ON_CALL(foo, Sign(Gt(0)))
+ .WillByDefault(Return(1));
+
+ EXPECT_CALL(foo, Sign(_))
+ .Times(AnyNumber());
+
+ foo.Sign(5); // This should return 1.
+ foo.Sign(-9); // This should return -1.
+ foo.Sign(0); // This should return 0.
+```
+
+As you may have guessed, when there are more than one `ON_CALL()` statements,
+the newer ones in the order take precedence over the older ones. In other words,
+the **last** one that matches the function arguments will be used. This matching
+order allows you to set up the common behavior in a mock object's constructor or
+the test fixture's set-up phase and specialize the mock's behavior later.
+
+Note that both `ON_CALL` and `EXPECT_CALL` have the same "later statements take
+precedence" rule, but they don't interact. That is, `EXPECT_CALL`s have their
+own precedence order distinct from the `ON_CALL` precedence order.
+
+### Using Functions/Methods/Functors/Lambdas as Actions {#FunctionsAsActions}
+
+If the built-in actions don't suit you, you can use an existing callable
+(function, `std::function`, method, functor, lambda) as an action.
+
+<!-- GOOGLETEST_CM0024 DO NOT DELETE -->
+
+```cpp
+using ::testing::_; using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, Sum, (int x, int y), (override));
+ MOCK_METHOD(bool, ComplexJob, (int x), (override));
+};
+
+int CalculateSum(int x, int y) { return x + y; }
+int Sum3(int x, int y, int z) { return x + y + z; }
+
+class Helper {
+ public:
+ bool ComplexJob(int x);
+};
+
+...
+ MockFoo foo;
+ Helper helper;
+ EXPECT_CALL(foo, Sum(_, _))
+ .WillOnce(&CalculateSum)
+ .WillRepeatedly(Invoke(NewPermanentCallback(Sum3, 1)));
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce(Invoke(&helper, &Helper::ComplexJob))
+ .WillOnce([] { return true; })
+ .WillRepeatedly([](int x) { return x > 0; });
+
+ foo.Sum(5, 6); // Invokes CalculateSum(5, 6).
+ foo.Sum(2, 3); // Invokes Sum3(1, 2, 3).
+ foo.ComplexJob(10); // Invokes helper.ComplexJob(10).
+ foo.ComplexJob(-1); // Invokes the inline lambda.
+```
+
+The only requirement is that the type of the function, etc must be *compatible*
+with the signature of the mock function, meaning that the latter's arguments (if
+it takes any) can be implicitly converted to the corresponding arguments of the
+former, and the former's return type can be implicitly converted to that of the
+latter. So, you can invoke something whose type is *not* exactly the same as the
+mock function, as long as it's safe to do so - nice, huh?
+
+**`Note:`{.escaped}**
+
+* The action takes ownership of the callback and will delete it when the
+ action itself is destructed.
+* If the type of a callback is derived from a base callback type `C`, you need
+ to implicitly cast it to `C` to resolve the overloading, e.g.
+
+ ```cpp
+ using ::testing::Invoke;
+ ...
+ ResultCallback<bool>* is_ok = ...;
+ ... Invoke(is_ok) ...; // This works.
+
+ BlockingClosure* done = new BlockingClosure;
+ ... Invoke(implicit_cast<Closure*>(done)) ...; // The cast is necessary.
+ ```
+
+### Using Functions with Extra Info as Actions
+
+The function or functor you call using `Invoke()` must have the same number of
+arguments as the mock function you use it for. Sometimes you may have a function
+that takes more arguments, and you are willing to pass in the extra arguments
+yourself to fill the gap. You can do this in gMock using callbacks with
+pre-bound arguments. Here's an example:
+
+```cpp
+using ::testing::Invoke;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(char, DoThis, (int n), (override));
+};
+
+char SignOfSum(int x, int y) {
+ const int sum = x + y;
+ return (sum > 0) ? '+' : (sum < 0) ? '-' : '0';
+}
+
+TEST_F(FooTest, Test) {
+ MockFoo foo;
+
+ EXPECT_CALL(foo, DoThis(2))
+ .WillOnce(Invoke(NewPermanentCallback(SignOfSum, 5)));
+ EXPECT_EQ('+', foo.DoThis(2)); // Invokes SignOfSum(5, 2).
+}
+```
+
+### Invoking a Function/Method/Functor/Lambda/Callback Without Arguments
+
+`Invoke()` passes the mock function's arguments to the function, etc being
+invoked such that the callee has the full context of the call to work with. If
+the invoked function is not interested in some or all of the arguments, it can
+simply ignore them.
+
+Yet, a common pattern is that a test author wants to invoke a function without
+the arguments of the mock function. She could do that using a wrapper function
+that throws away the arguments before invoking an underlining nullary function.
+Needless to say, this can be tedious and obscures the intent of the test.
+
+There are two solutions to this problem. First, you can pass any callable of
+zero args as an action. Alternatively, use `InvokeWithoutArgs()`, which is like
+`Invoke()` except that it doesn't pass the mock function's arguments to the
+callee. Here's an example of each:
+
+```cpp
+using ::testing::_;
+using ::testing::InvokeWithoutArgs;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, ComplexJob, (int n), (override));
+};
+
+bool Job1() { ... }
+bool Job2(int n, char c) { ... }
+
+...
+ MockFoo foo;
+ EXPECT_CALL(foo, ComplexJob(_))
+ .WillOnce([] { Job1(); });
+ .WillOnce(InvokeWithoutArgs(NewPermanentCallback(Job2, 5, 'a')));
+
+ foo.ComplexJob(10); // Invokes Job1().
+ foo.ComplexJob(20); // Invokes Job2(5, 'a').
+```
+
+**`Note:`{.escaped}**
+
+* The action takes ownership of the callback and will delete it when the
+ action itself is destructed.
+* If the type of a callback is derived from a base callback type `C`, you need
+ to implicitly cast it to `C` to resolve the overloading, e.g.
+
+ ```cpp
+ using ::testing::InvokeWithoutArgs;
+ ...
+ ResultCallback<bool>* is_ok = ...;
+ ... InvokeWithoutArgs(is_ok) ...; // This works.
+
+ BlockingClosure* done = ...;
+ ... InvokeWithoutArgs(implicit_cast<Closure*>(done)) ...;
+ // The cast is necessary.
+ ```
+
+### Invoking an Argument of the Mock Function
+
+Sometimes a mock function will receive a function pointer, a functor (in other
+words, a "callable") as an argument, e.g.
+
+```cpp
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(bool, DoThis, (int n, (ResultCallback1<bool, int>* callback)),
+ (override));
+};
+```
+
+and you may want to invoke this callable argument:
+
+```cpp
+using ::testing::_;
+...
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(...);
+ // Will execute callback->Run(5), where callback is the
+ // second argument DoThis() receives.
+```
+
+NOTE: The section below is legacy documentation from before C++ had lambdas:
+
+Arghh, you need to refer to a mock function argument but C++ has no lambda
+(yet), so you have to define your own action. :-( Or do you really?
+
+Well, gMock has an action to solve *exactly* this problem:
+
+```cpp
+InvokeArgument<N>(arg_1, arg_2, ..., arg_m)
+```
+
+will invoke the `N`-th (0-based) argument the mock function receives, with
+`arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is a function
+pointer, a functor, or a callback. gMock handles them all.
+
+With that, you could write:
+
+```cpp
+using ::testing::_;
+using ::testing::InvokeArgument;
+...
+ EXPECT_CALL(foo, DoThis(_, _))
+ .WillOnce(InvokeArgument<1>(5));
+ // Will execute callback->Run(5), where callback is the
+ // second argument DoThis() receives.
+```
+
+What if the callable takes an argument by reference? No problem - just wrap it
+inside `std::ref()`:
+
+```cpp
+ ...
+ MOCK_METHOD(bool, Bar,
+ ((ResultCallback2<bool, int, const Helper&>* callback)),
+ (override));
+ ...
+ using ::testing::_;
+ using ::testing::InvokeArgument;
+ ...
+ MockFoo foo;
+ Helper helper;
+ ...
+ EXPECT_CALL(foo, Bar(_))
+ .WillOnce(InvokeArgument<0>(5, std::ref(helper)));
+ // std::ref(helper) guarantees that a reference to helper, not a copy of
+ // it, will be passed to the callback.
+```
+
+What if the callable takes an argument by reference and we do **not** wrap the
+argument in `std::ref()`? Then `InvokeArgument()` will *make a copy* of the
+argument, and pass a *reference to the copy*, instead of a reference to the
+original value, to the callable. This is especially handy when the argument is a
+temporary value:
+
+```cpp
+ ...
+ MOCK_METHOD(bool, DoThat, (bool (*f)(const double& x, const string& s)),
+ (override));
+ ...
+ using ::testing::_;
+ using ::testing::InvokeArgument;
+ ...
+ MockFoo foo;
+ ...
+ EXPECT_CALL(foo, DoThat(_))
+ .WillOnce(InvokeArgument<0>(5.0, string("Hi")));
+ // Will execute (*f)(5.0, string("Hi")), where f is the function pointer
+ // DoThat() receives. Note that the values 5.0 and string("Hi") are
+ // temporary and dead once the EXPECT_CALL() statement finishes. Yet
+ // it's fine to perform this action later, since a copy of the values
+ // are kept inside the InvokeArgument action.
+```
+
+### Ignoring an Action's Result
+
+Sometimes you have an action that returns *something*, but you need an action
+that returns `void` (perhaps you want to use it in a mock function that returns
+`void`, or perhaps it needs to be used in `DoAll()` and it's not the last in the
+list). `IgnoreResult()` lets you do that. For example:
+
+```cpp
+using ::testing::_;
+using ::testing::DoAll;
+using ::testing::IgnoreResult;
+using ::testing::Return;
+
+int Process(const MyData& data);
+string DoSomething();
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(void, Abc, (const MyData& data), (override));
+ MOCK_METHOD(bool, Xyz, (), (override));
+};
+
+ ...
+ MockFoo foo;
+ EXPECT_CALL(foo, Abc(_))
+ // .WillOnce(Invoke(Process));
+ // The above line won't compile as Process() returns int but Abc() needs
+ // to return void.
+ .WillOnce(IgnoreResult(Process));
+ EXPECT_CALL(foo, Xyz())
+ .WillOnce(DoAll(IgnoreResult(DoSomething),
+ // Ignores the string DoSomething() returns.
+ Return(true)));
+```
+
+Note that you **cannot** use `IgnoreResult()` on an action that already returns
+`void`. Doing so will lead to ugly compiler errors.
+
+### Selecting an Action's Arguments {#SelectingArgs}
+
+Say you have a mock function `Foo()` that takes seven arguments, and you have a
+custom action that you want to invoke when `Foo()` is called. Trouble is, the
+custom action only wants three arguments:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+...
+ MOCK_METHOD(bool, Foo,
+ (bool visible, const string& name, int x, int y,
+ (const map<pair<int, int>>), double& weight, double min_weight,
+ double max_wight));
+...
+bool IsVisibleInQuadrant1(bool visible, int x, int y) {
+ return visible && x >= 0 && y >= 0;
+}
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(Invoke(IsVisibleInQuadrant1)); // Uh, won't compile. :-(
+```
+
+To please the compiler God, you need to define an "adaptor" that has the same
+signature as `Foo()` and calls the custom action with the right arguments:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+...
+bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y,
+ const map<pair<int, int>, double>& weight,
+ double min_weight, double max_wight) {
+ return IsVisibleInQuadrant1(visible, x, y);
+}
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(Invoke(MyIsVisibleInQuadrant1)); // Now it works.
+```
+
+But isn't this awkward?
+
+gMock provides a generic *action adaptor*, so you can spend your time minding
+more important business than writing your own adaptors. Here's the syntax:
+
+```cpp
+WithArgs<N1, N2, ..., Nk>(action)
+```
+
+creates an action that passes the arguments of the mock function at the given
+indices (0-based) to the inner `action` and performs it. Using `WithArgs`, our
+original example can be written as:
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::WithArgs;
+...
+ EXPECT_CALL(mock, Foo)
+ .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1))); // No need to define your own adaptor.
+```
+
+For better readability, gMock also gives you:
+
+* `WithoutArgs(action)` when the inner `action` takes *no* argument, and
+* `WithArg<N>(action)` (no `s` after `Arg`) when the inner `action` takes
+ *one* argument.
+
+As you may have realized, `InvokeWithoutArgs(...)` is just syntactic sugar for
+`WithoutArgs(Invoke(...))`.
+
+Here are more tips:
+
+* The inner action used in `WithArgs` and friends does not have to be
+ `Invoke()` -- it can be anything.
+* You can repeat an argument in the argument list if necessary, e.g.
+ `WithArgs<2, 3, 3, 5>(...)`.
+* You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`.
+* The types of the selected arguments do *not* have to match the signature of
+ the inner action exactly. It works as long as they can be implicitly
+ converted to the corresponding arguments of the inner action. For example,
+ if the 4-th argument of the mock function is an `int` and `my_action` takes
+ a `double`, `WithArg<4>(my_action)` will work.
+
+### Ignoring Arguments in Action Functions
+
+The [selecting-an-action's-arguments](#SelectingArgs) recipe showed us one way
+to make a mock function and an action with incompatible argument lists fit
+together. The downside is that wrapping the action in `WithArgs<...>()` can get
+tedious for people writing the tests.
+
+If you are defining a function (or method, functor, lambda, callback) to be used
+with `Invoke*()`, and you are not interested in some of its arguments, an
+alternative to `WithArgs` is to declare the uninteresting arguments as `Unused`.
+This makes the definition less cluttered and less fragile in case the types of
+the uninteresting arguments change. It could also increase the chance the action
+function can be reused. For example, given
+
+```cpp
+ public:
+ MOCK_METHOD(double, Foo, double(const string& label, double x, double y),
+ (override));
+ MOCK_METHOD(double, Bar, (int index, double x, double y), (override));
+```
+
+instead of
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+
+double DistanceToOriginWithLabel(const string& label, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+double DistanceToOriginWithIndex(int index, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+ EXPECT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOriginWithLabel));
+ EXPECT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOriginWithIndex));
+```
+
+you could write
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+using ::testing::Unused;
+
+double DistanceToOrigin(Unused, double x, double y) {
+ return sqrt(x*x + y*y);
+}
+...
+ EXPECT_CALL(mock, Foo("abc", _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+ EXPECT_CALL(mock, Bar(5, _, _))
+ .WillOnce(Invoke(DistanceToOrigin));
+```
+
+### Sharing Actions
+
+Just like matchers, a gMock action object consists of a pointer to a ref-counted
+implementation object. Therefore copying actions is also allowed and very
+efficient. When the last action that references the implementation object dies,
+the implementation object will be deleted.
+
+If you have some complex action that you want to use again and again, you may
+not have to build it from scratch everytime. If the action doesn't have an
+internal state (i.e. if it always does the same thing no matter how many times
+it has been called), you can assign it to an action variable and use that
+variable repeatedly. For example:
+
+```cpp
+using ::testing::Action;
+using ::testing::DoAll;
+using ::testing::Return;
+using ::testing::SetArgPointee;
+...
+ Action<bool(int*)> set_flag = DoAll(SetArgPointee<0>(5),
+ Return(true));
+ ... use set_flag in .WillOnce() and .WillRepeatedly() ...
+```
+
+However, if the action has its own state, you may be surprised if you share the
+action object. Suppose you have an action factory `IncrementCounter(init)` which
+creates an action that increments and returns a counter whose initial value is
+`init`, using two actions created from the same expression and using a shared
+action will exhibit different behaviors. Example:
+
+```cpp
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(IncrementCounter(0));
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(IncrementCounter(0));
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 1 - Blah() uses a different
+ // counter than Bar()'s.
+```
+
+versus
+
+```cpp
+using ::testing::Action;
+...
+ Action<int()> increment = IncrementCounter(0);
+ EXPECT_CALL(foo, DoThis())
+ .WillRepeatedly(increment);
+ EXPECT_CALL(foo, DoThat())
+ .WillRepeatedly(increment);
+ foo.DoThis(); // Returns 1.
+ foo.DoThis(); // Returns 2.
+ foo.DoThat(); // Returns 3 - the counter is shared.
+```
+
+### Testing Asynchronous Behavior
+
+One oft-encountered problem with gMock is that it can be hard to test
+asynchronous behavior. Suppose you had a `EventQueue` class that you wanted to
+test, and you created a separate `EventDispatcher` interface so that you could
+easily mock it out. However, the implementation of the class fired all the
+events on a background thread, which made test timings difficult. You could just
+insert `sleep()` statements and hope for the best, but that makes your test
+behavior nondeterministic. A better way is to use gMock actions and
+`Notification` objects to force your asynchronous test to behave synchronously.
+
+```cpp
+using ::testing::DoAll;
+using ::testing::InvokeWithoutArgs;
+using ::testing::Return;
+
+class MockEventDispatcher : public EventDispatcher {
+ MOCK_METHOD(bool, DispatchEvent, (int32), (override));
+};
+
+ACTION_P(Notify, notification) {
+ notification->Notify();
+}
+
+TEST(EventQueueTest, EnqueueEventTest) {
+ MockEventDispatcher mock_event_dispatcher;
+ EventQueue event_queue(&mock_event_dispatcher);
+
+ const int32 kEventId = 321;
+ absl::Notification done;
+ EXPECT_CALL(mock_event_dispatcher, DispatchEvent(kEventId))
+ .WillOnce(Notify(&done));
+
+ event_queue.EnqueueEvent(kEventId);
+ done.WaitForNotification();
+}
+```
+
+In the example above, we set our normal gMock expectations, but then add an
+additional action to notify the `Notification` object. Now we can just call
+`Notification::WaitForNotification()` in the main thread to wait for the
+asynchronous call to finish. After that, our test suite is complete and we can
+safely exit.
+
+Note: this example has a downside: namely, if the expectation is not satisfied,
+our test will run forever. It will eventually time-out and fail, but it will
+take longer and be slightly harder to debug. To alleviate this problem, you can
+use `WaitForNotificationWithTimeout(ms)` instead of `WaitForNotification()`.
+
+## Misc Recipes on Using gMock
+
+### Mocking Methods That Use Move-Only Types
+
+C++11 introduced *move-only types*. A move-only-typed value can be moved from
+one object to another, but cannot be copied. `std::unique_ptr<T>` is probably
+the most commonly used move-only type.
+
+Mocking a method that takes and/or returns move-only types presents some
+challenges, but nothing insurmountable. This recipe shows you how you can do it.
+Note that the support for move-only method arguments was only introduced to
+gMock in April 2017; in older code, you may find more complex
+[workarounds](#LegacyMoveOnly) for lack of this feature.
+
+Let’s say we are working on a fictional project that lets one post and share
+snippets called “buzzes”. Your code uses these types:
+
+```cpp
+enum class AccessLevel { kInternal, kPublic };
+
+class Buzz {
+ public:
+ explicit Buzz(AccessLevel access) { ... }
+ ...
+};
+
+class Buzzer {
+ public:
+ virtual ~Buzzer() {}
+ virtual std::unique_ptr<Buzz> MakeBuzz(StringPiece text) = 0;
+ virtual bool ShareBuzz(std::unique_ptr<Buzz> buzz, int64_t timestamp) = 0;
+ ...
+};
+```
+
+A `Buzz` object represents a snippet being posted. A class that implements the
+`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in
+`Buzzer` may return a `unique_ptr<Buzz>` or take a `unique_ptr<Buzz>`. Now we
+need to mock `Buzzer` in our tests.
+
+To mock a method that accepts or returns move-only types, you just use the
+familiar `MOCK_METHOD` syntax as usual:
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD(std::unique_ptr<Buzz>, MakeBuzz, (StringPiece text), (override));
+ MOCK_METHOD(bool, ShareBuzz, (std::unique_ptr<Buzz> buzz, int64_t timestamp),
+ (override));
+};
+```
+
+Now that we have the mock class defined, we can use it in tests. In the
+following code examples, we assume that we have defined a `MockBuzzer` object
+named `mock_buzzer_`:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+```
+
+First let’s see how we can set expectations on the `MakeBuzz()` method, which
+returns a `unique_ptr<Buzz>`.
+
+As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or
+`.WillRepeatedly()` clause), when that expectation fires, the default action for
+that method will be taken. Since `unique_ptr<>` has a default constructor that
+returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an
+action:
+
+```cpp
+ // Use the default action.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("hello"));
+
+ // Triggers the previous EXPECT_CALL.
+ EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello"));
+```
+
+If you are not happy with the default action, you can tweak it as usual; see
+[Setting Default Actions](#OnCall).
+
+If you just need to return a pre-defined move-only value, you can use the
+`Return(ByMove(...))` action:
+
+```cpp
+ // When this fires, the unique_ptr<> specified by ByMove(...) will
+ // be returned.
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("world"))
+ .WillOnce(Return(ByMove(MakeUnique<Buzz>(AccessLevel::kInternal))));
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world"));
+```
+
+Note that `ByMove()` is essential here - if you drop it, the code won’t compile.
+
+Quiz time! What do you think will happen if a `Return(ByMove(...))` action is
+performed more than once (e.g. you write `...
+.WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first time
+the action runs, the source value will be consumed (since it’s a move-only
+value), so the next time around, there’s no value to move from -- you’ll get a
+run-time error that `Return(ByMove(...))` can only be run once.
+
+If you need your mock method to do more than just moving a pre-defined value,
+remember that you can always use a lambda or a callable object, which can do
+pretty much anything you want:
+
+```cpp
+ EXPECT_CALL(mock_buzzer_, MakeBuzz("x"))
+ .WillRepeatedly([](StringPiece text) {
+ return MakeUnique<Buzz>(AccessLevel::kInternal);
+ });
+
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+ EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
+```
+
+Every time this `EXPECT_CALL` fires, a new `unique_ptr<Buzz>` will be created
+and returned. You cannot do this with `Return(ByMove(...))`.
+
+That covers returning move-only values; but how do we work with methods
+accepting move-only arguments? The answer is that they work normally, although
+some actions will not compile when any of method's arguments are move-only. You
+can always use `Return`, or a [lambda or functor](#FunctionsAsActions):
+
+```cpp
+ using ::testing::Unused;
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)).WillOnce(Return(true));
+ EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal)),
+ 0);
+
+ EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)).WillOnce(
+ [](std::unique_ptr<Buzz> buzz, Unused) { return buzz != nullptr; });
+ EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0));
+```
+
+Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...)
+could in principle support move-only arguments, but the support for this is not
+implemented yet. If this is blocking you, please file a bug.
+
+A few actions (e.g. `DoAll`) copy their arguments internally, so they can never
+work with non-copyable objects; you'll have to use functors instead.
+
+#### Legacy workarounds for move-only types {#LegacyMoveOnly}
+
+Support for move-only function arguments was only introduced to gMock in April
+2017. In older code, you may encounter the following workaround for the lack of
+this feature (it is no longer necessary - we're including it just for
+reference):
+
+```cpp
+class MockBuzzer : public Buzzer {
+ public:
+ MOCK_METHOD(bool, DoShareBuzz, (Buzz* buzz, Time timestamp));
+ bool ShareBuzz(std::unique_ptr<Buzz> buzz, Time timestamp) override {
+ return DoShareBuzz(buzz.get(), timestamp);
+ }
+};
+```
+
+The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call
+it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of
+setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock
+method:
+
+```cpp
+ MockBuzzer mock_buzzer_;
+ EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _));
+
+ // When one calls ShareBuzz() on the MockBuzzer like this, the call is
+ // forwarded to DoShareBuzz(), which is mocked. Therefore this statement
+ // will trigger the above EXPECT_CALL.
+ mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal), 0);
+```
+
+### Making the Compilation Faster
+
+Believe it or not, the *vast majority* of the time spent on compiling a mock
+class is in generating its constructor and destructor, as they perform
+non-trivial tasks (e.g. verification of the expectations). What's more, mock
+methods with different signatures have different types and thus their
+constructors/destructors need to be generated by the compiler separately. As a
+result, if you mock many different types of methods, compiling your mock class
+can get really slow.
+
+If you are experiencing slow compilation, you can move the definition of your
+mock class' constructor and destructor out of the class body and into a `.cc`
+file. This way, even if you `#include` your mock class in N files, the compiler
+only needs to generate its constructor and destructor once, resulting in a much
+faster compilation.
+
+Let's illustrate the idea using an example. Here's the definition of a mock
+class before applying this recipe:
+
+```cpp
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // Since we don't declare the constructor or the destructor,
+ // the compiler will generate them in every translation unit
+ // where this mock class is used.
+
+ MOCK_METHOD(int, DoThis, (), (override));
+ MOCK_METHOD(bool, DoThat, (const char* str), (override));
+ ... more mock methods ...
+};
+```
+
+After the change, it would look like:
+
+```cpp
+// File mock_foo.h.
+...
+class MockFoo : public Foo {
+ public:
+ // The constructor and destructor are declared, but not defined, here.
+ MockFoo();
+ virtual ~MockFoo();
+
+ MOCK_METHOD(int, DoThis, (), (override));
+ MOCK_METHOD(bool, DoThat, (const char* str), (override));
+ ... more mock methods ...
+};
+```
+
+and
+
+```cpp
+// File mock_foo.cc.
+#include "path/to/mock_foo.h"
+
+// The definitions may appear trivial, but the functions actually do a
+// lot of things through the constructors/destructors of the member
+// variables used to implement the mock methods.
+MockFoo::MockFoo() {}
+MockFoo::~MockFoo() {}
+```
+
+### Forcing a Verification
+
+When it's being destroyed, your friendly mock object will automatically verify
+that all expectations on it have been satisfied, and will generate googletest
+failures if not. This is convenient as it leaves you with one less thing to
+worry about. That is, unless you are not sure if your mock object will be
+destroyed.
+
+How could it be that your mock object won't eventually be destroyed? Well, it
+might be created on the heap and owned by the code you are testing. Suppose
+there's a bug in that code and it doesn't delete the mock object properly - you
+could end up with a passing test when there's actually a bug.
+
+Using a heap checker is a good idea and can alleviate the concern, but its
+implementation is not 100% reliable. So, sometimes you do want to *force* gMock
+to verify a mock object before it is (hopefully) destructed. You can do this
+with `Mock::VerifyAndClearExpectations(&mock_object)`:
+
+```cpp
+TEST(MyServerTest, ProcessesRequest) {
+ using ::testing::Mock;
+
+ MockFoo* const foo = new MockFoo;
+ EXPECT_CALL(*foo, ...)...;
+ // ... other expectations ...
+
+ // server now owns foo.
+ MyServer server(foo);
+ server.ProcessRequest(...);
+
+ // In case that server's destructor will forget to delete foo,
+ // this will verify the expectations anyway.
+ Mock::VerifyAndClearExpectations(foo);
+} // server is destroyed when it goes out of scope here.
+```
+
+**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a `bool` to
+indicate whether the verification was successful (`true` for yes), so you can
+wrap that function call inside a `ASSERT_TRUE()` if there is no point going
+further when the verification has failed.
+
+### Using Check Points {#UsingCheckPoints}
+
+Sometimes you may want to "reset" a mock object at various check points in your
+test: at each check point, you verify that all existing expectations on the mock
+object have been satisfied, and then you set some new expectations on it as if
+it's newly created. This allows you to work with a mock object in "phases" whose
+sizes are each manageable.
+
+One such scenario is that in your test's `SetUp()` function, you may want to put
+the object you are testing into a certain state, with the help from a mock
+object. Once in the desired state, you want to clear all expectations on the
+mock, such that in the `TEST_F` body you can set fresh expectations on it.
+
+As you may have figured out, the `Mock::VerifyAndClearExpectations()` function
+we saw in the previous recipe can help you here. Or, if you are using
+`ON_CALL()` to set default actions on the mock object and want to clear the
+default actions as well, use `Mock::VerifyAndClear(&mock_object)` instead. This
+function does what `Mock::VerifyAndClearExpectations(&mock_object)` does and
+returns the same `bool`, **plus** it clears the `ON_CALL()` statements on
+`mock_object` too.
+
+Another trick you can use to achieve the same effect is to put the expectations
+in sequences and insert calls to a dummy "check-point" function at specific
+places. Then you can verify that the mock function calls do happen at the right
+time. For example, if you are exercising code:
+
+```cpp
+ Foo(1);
+ Foo(2);
+ Foo(3);
+```
+
+and want to verify that `Foo(1)` and `Foo(3)` both invoke `mock.Bar("a")`, but
+`Foo(2)` doesn't invoke anything. You can write:
+
+```cpp
+using ::testing::MockFunction;
+
+TEST(FooTest, InvokesBarCorrectly) {
+ MyMock mock;
+ // Class MockFunction<F> has exactly one mock method. It is named
+ // Call() and has type F.
+ MockFunction<void(string check_point_name)> check;
+ {
+ InSequence s;
+
+ EXPECT_CALL(mock, Bar("a"));
+ EXPECT_CALL(check, Call("1"));
+ EXPECT_CALL(check, Call("2"));
+ EXPECT_CALL(mock, Bar("a"));
+ }
+ Foo(1);
+ check.Call("1");
+ Foo(2);
+ check.Call("2");
+ Foo(3);
+}
+```
+
+The expectation spec says that the first `Bar("a")` must happen before check
+point "1", the second `Bar("a")` must happen after check point "2", and nothing
+should happen between the two check points. The explicit check points make it
+easy to tell which `Bar("a")` is called by which call to `Foo()`.
+
+### Mocking Destructors
+
+Sometimes you want to make sure a mock object is destructed at the right time,
+e.g. after `bar->A()` is called but before `bar->B()` is called. We already know
+that you can specify constraints on the [order](#OrderedCalls) of mock function
+calls, so all we need to do is to mock the destructor of the mock function.
+
+This sounds simple, except for one problem: a destructor is a special function
+with special syntax and special semantics, and the `MOCK_METHOD` macro doesn't
+work for it:
+
+```cpp
+MOCK_METHOD(void, ~MockFoo, ()); // Won't compile!
+```
+
+The good news is that you can use a simple pattern to achieve the same effect.
+First, add a mock function `Die()` to your mock class and call it in the
+destructor, like this:
+
+```cpp
+class MockFoo : public Foo {
+ ...
+ // Add the following two lines to the mock class.
+ MOCK_METHOD(void, Die, ());
+ ~MockFoo() override { Die(); }
+};
+```
+
+(If the name `Die()` clashes with an existing symbol, choose another name.) Now,
+we have translated the problem of testing when a `MockFoo` object dies to
+testing when its `Die()` method is called:
+
+```cpp
+ MockFoo* foo = new MockFoo;
+ MockBar* bar = new MockBar;
+ ...
+ {
+ InSequence s;
+
+ // Expects *foo to die after bar->A() and before bar->B().
+ EXPECT_CALL(*bar, A());
+ EXPECT_CALL(*foo, Die());
+ EXPECT_CALL(*bar, B());
+ }
+```
+
+And that's that.
+
+### Using gMock and Threads {#UsingThreads}
+
+In a **unit** test, it's best if you could isolate and test a piece of code in a
+single-threaded context. That avoids race conditions and dead locks, and makes
+debugging your test much easier.
+
+Yet most programs are multi-threaded, and sometimes to test something we need to
+pound on it from more than one thread. gMock works for this purpose too.
+
+Remember the steps for using a mock:
+
+1. Create a mock object `foo`.
+2. Set its default actions and expectations using `ON_CALL()` and
+ `EXPECT_CALL()`.
+3. The code under test calls methods of `foo`.
+4. Optionally, verify and reset the mock.
+5. Destroy the mock yourself, or let the code under test destroy it. The
+ destructor will automatically verify it.
+
+If you follow the following simple rules, your mocks and threads can live
+happily together:
+
+* Execute your *test code* (as opposed to the code being tested) in *one*
+ thread. This makes your test easy to follow.
+* Obviously, you can do step #1 without locking.
+* When doing step #2 and #5, make sure no other thread is accessing `foo`.
+ Obvious too, huh?
+* #3 and #4 can be done either in one thread or in multiple threads - anyway
+ you want. gMock takes care of the locking, so you don't have to do any -
+ unless required by your test logic.
+
+If you violate the rules (for example, if you set expectations on a mock while
+another thread is calling its methods), you get undefined behavior. That's not
+fun, so don't do it.
+
+gMock guarantees that the action for a mock function is done in the same thread
+that called the mock function. For example, in
+
+```cpp
+ EXPECT_CALL(mock, Foo(1))
+ .WillOnce(action1);
+ EXPECT_CALL(mock, Foo(2))
+ .WillOnce(action2);
+```
+
+if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2, gMock will
+execute `action1` in thread 1 and `action2` in thread 2.
+
+gMock does *not* impose a sequence on actions performed in different threads
+(doing so may create deadlocks as the actions may need to cooperate). This means
+that the execution of `action1` and `action2` in the above example *may*
+interleave. If this is a problem, you should add proper synchronization logic to
+`action1` and `action2` to make the test thread-safe.
+
+Also, remember that `DefaultValue<T>` is a global resource that potentially
+affects *all* living mock objects in your program. Naturally, you won't want to
+mess with it from multiple threads or when there still are mocks in action.
+
+### Controlling How Much Information gMock Prints
+
+When gMock sees something that has the potential of being an error (e.g. a mock
+function with no expectation is called, a.k.a. an uninteresting call, which is
+allowed but perhaps you forgot to explicitly ban the call), it prints some
+warning messages, including the arguments of the function, the return value, and
+the stack trace. Hopefully this will remind you to take a look and see if there
+is indeed a problem.
+
+Sometimes you are confident that your tests are correct and may not appreciate
+such friendly messages. Some other times, you are debugging your tests or
+learning about the behavior of the code you are testing, and wish you could
+observe every mock call that happens (including argument values, the return
+value, and the stack trace). Clearly, one size doesn't fit all.
+
+You can control how much gMock tells you using the `--gmock_verbose=LEVEL`
+command-line flag, where `LEVEL` is a string with three possible values:
+
+* `info`: gMock will print all informational messages, warnings, and errors
+ (most verbose). At this setting, gMock will also log any calls to the
+ `ON_CALL/EXPECT_CALL` macros. It will include a stack trace in
+ "uninteresting call" warnings.
+* `warning`: gMock will print both warnings and errors (less verbose); it will
+ omit the stack traces in "uninteresting call" warnings. This is the default.
+* `error`: gMock will print errors only (least verbose).
+
+Alternatively, you can adjust the value of that flag from within your tests like
+so:
+
+```cpp
+ ::testing::FLAGS_gmock_verbose = "error";
+```
+
+If you find gMock printing too many stack frames with its informational or
+warning messages, remember that you can control their amount with the
+`--gtest_stack_trace_depth=max_depth` flag.
+
+Now, judiciously use the right flag to enable gMock serve you better!
+
+### Gaining Super Vision into Mock Calls
+
+You have a test using gMock. It fails: gMock tells you some expectations aren't
+satisfied. However, you aren't sure why: Is there a typo somewhere in the
+matchers? Did you mess up the order of the `EXPECT_CALL`s? Or is the code under
+test doing something wrong? How can you find out the cause?
+
+Won't it be nice if you have X-ray vision and can actually see the trace of all
+`EXPECT_CALL`s and mock method calls as they are made? For each call, would you
+like to see its actual argument values and which `EXPECT_CALL` gMock thinks it
+matches? If you still need some help to figure out who made these calls, how
+about being able to see the complete stack trace at each mock call?
+
+You can unlock this power by running your test with the `--gmock_verbose=info`
+flag. For example, given the test program:
+
+```cpp
+#include "gmock/gmock.h"
+
+using testing::_;
+using testing::HasSubstr;
+using testing::Return;
+
+class MockFoo {
+ public:
+ MOCK_METHOD(void, F, (const string& x, const string& y));
+};
+
+TEST(Foo, Bar) {
+ MockFoo mock;
+ EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return());
+ EXPECT_CALL(mock, F("a", "b"));
+ EXPECT_CALL(mock, F("c", HasSubstr("d")));
+
+ mock.F("a", "good");
+ mock.F("a", "b");
+}
+```
+
+if you run it with `--gmock_verbose=info`, you will see this output:
+
+```shell
+[ RUN ] Foo.Bar
+
+foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked
+Stack trace: ...
+
+foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked
+Stack trace: ...
+
+foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked
+Stack trace: ...
+
+foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))...
+ Function call: F(@0x7fff7c8dad40"a",@0x7fff7c8dad10"good")
+Stack trace: ...

+ Expected: to be called once
+ Actual: never called - unsatisfied and active
+[ FAILED ] Foo.Bar
+```
+
+Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo and
+should actually be `"a"`. With the above message, you should see that the actual
+`F("a", "good")` call is matched by the first `EXPECT_CALL`, not the third as
+you thought. From that it should be obvious that the third `EXPECT_CALL` is
+written wrong. Case solved.
+
+If you are interested in the mock call trace but not the stack traces, you can
+combine `--gmock_verbose=info` with `--gtest_stack_trace_depth=0` on the test
+command line.

+### Running Tests in Emacs
+
+If you build and run your tests in Emacs using the `M-x google-compile` command
+(as many googletest users do), the source file locations of gMock and googletest
+errors will be highlighted. Just press `<Enter>` on one of them and you'll be
+taken to the offending line. Or, you can just type `C-x`` to jump to the next
+error.
+
+To make it even easier, you can add the following lines to your `~/.emacs` file:
+
+```text
+(global-set-key "\M-m" 'google-compile) ; m is for make
+(global-set-key [M-down] 'next-error)
+(global-set-key [M-up] '(lambda () (interactive) (next-error -1)))
+```
+
+Then you can type `M-m` to start a build (if you want to run the test as well,
+just make sure `foo_test.run` or `runtests` is in the build command you supply
+after typing `M-m`), or `M-up`/`M-down` to move back and forth between errors.
+
+## Extending gMock
+
+### Writing New Matchers Quickly {#NewMatchers}
+
+WARNING: gMock does not guarantee when or how many times a matcher will be
+invoked. Therefore, all matchers must be functionally pure. See
+[this section](#PureMatchers) for more details.
+
+The `MATCHER*` family of macros can be used to define custom matchers easily.
+The syntax:
+
+```cpp
+MATCHER(name, description_string_expression) { statements; }
+```
+
+will define a matcher with the given name that executes the statements, which
+must return a `bool` to indicate if the match succeeds. Inside the statements,
+you can refer to the value being matched by `arg`, and refer to its type by
+`arg_type`.
+
+The *description string* is a `string`-typed expression that documents what the
+matcher does, and is used to generate the failure message when the match fails.
+It can (and should) reference the special `bool` variable `negation`, and should
+evaluate to the description of the matcher when `negation` is `false`, or that
+of the matcher's negation when `negation` is `true`.
+
+For convenience, we allow the description string to be empty (`""`), in which
+case gMock will use the sequence of words in the matcher name as the
+description.
+
+For example:
+
+```cpp
+MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; }
+```
+
+allows you to write
+
+```cpp
+ // Expects mock_foo.Bar(n) to be called where n is divisible by 7.
+ EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7()));
+```
+
+or,
+
+```cpp
+ using ::testing::Not;
+ ...
+ // Verifies that two values are divisible by 7.
+ EXPECT_THAT(some_expression, IsDivisibleBy7());
+ EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7()));
+```
+
+If the above assertions fail, they will print something like:
+
+```shell
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27
+ ...
+ Value of: some_other_expression
+ Expected: not (is divisible by 7)
+ Actual: 21
+```
+
+where the descriptions `"is divisible by 7"` and `"not (is divisible by 7)"` are
+automatically calculated from the matcher name `IsDivisibleBy7`.
+
+As you may have noticed, the auto-generated descriptions (especially those for
+the negation) may not be so great. You can always override them with a `string`
+expression of your own:
+
+```cpp
+MATCHER(IsDivisibleBy7,
+ absl::StrCat(negation ? "isn't" : "is", " divisible by 7")) {
+ return (arg % 7) == 0;
+}
+```
+
+Optionally, you can stream additional information to a hidden argument named
+`result_listener` to explain the match result. For example, a better definition
+of `IsDivisibleBy7` is:
+
+```cpp
+MATCHER(IsDivisibleBy7, "") {
+ if ((arg % 7) == 0)
+ return true;
+
+ *result_listener << "the remainder is " << (arg % 7);
+ return false;
+}
+```
+
+With this definition, the above assertion will give a better message:
+
+```shell
+ Value of: some_expression
+ Expected: is divisible by 7
+ Actual: 27 (the remainder is 6)
+```
+
+You should let `MatchAndExplain()` print *any additional information* that can
+help a user understand the match result. Note that it should explain why the
+match succeeds in case of a success (unless it's obvious) - this is useful when
+the matcher is used inside `Not()`. There is no need to print the argument value
+itself, as gMock already prints it for you.
+
+NOTE: The type of the value being matched (`arg_type`) is determined by the
+context in which you use the matcher and is supplied to you by the compiler, so
+you don't need to worry about declaring it (nor can you). This allows the
+matcher to be polymorphic. For example, `IsDivisibleBy7()` can be used to match
+any type where the value of `(arg % 7) == 0` can be implicitly converted to a
+`bool`. In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an
+`int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will
+be `unsigned long`; and so on.
+
+### Writing New Parameterized Matchers Quickly
+
+Sometimes you'll want to define a matcher that has parameters. For that you can
+use the macro:
+
+```cpp
+MATCHER_P(name, param_name, description_string) { statements; }
+```
+
+where the description string can be either `""` or a `string` expression that
+references `negation` and `param_name`.
+
+For example:
+
+```cpp
+MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+```
+
+will allow you to write:
+
+```cpp
+ EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+```
+
+which may lead to this message (assuming `n` is 10):
+
+```shell
+ Value of: Blah("a")
+ Expected: has absolute value 10
+ Actual: -9
+```
+
+Note that both the matcher description and its parameter are printed, making the
+message human-friendly.
+
+In the matcher definition body, you can write `foo_type` to reference the type
+of a parameter named `foo`. For example, in the body of
+`MATCHER_P(HasAbsoluteValue, value)` above, you can write `value_type` to refer
+to the type of `value`.
+
+gMock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to `MATCHER_P10` to
+support multi-parameter matchers:
+
+```cpp
+MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; }
+```
+
+Please note that the custom description string is for a particular *instance* of
+the matcher, where the parameters have been bound to actual values. Therefore
+usually you'll want the parameter values to be part of the description. gMock
+lets you do that by referencing the matcher parameters in the description string
+expression.
+
+For example,
+
+```cpp
+using ::testing::PrintToString;
+MATCHER_P2(InClosedRange, low, hi,
+ absl::StrFormat("%s in range [%s, %s]", negation ? "isn't" : "is",
+ PrintToString(low), PrintToString(hi))) {
+ return low <= arg && arg <= hi;
+}
+...
+EXPECT_THAT(3, InClosedRange(4, 6));
+```
+
+would generate a failure that contains the message:
+
+```shell
+ Expected: is in range [4, 6]
+```
+
+If you specify `""` as the description, the failure message will contain the
+sequence of words in the matcher name followed by the parameter values printed
+as a tuple. For example,
+
+```cpp
+ MATCHER_P2(InClosedRange, low, hi, "") { ... }
+ ...
+ EXPECT_THAT(3, InClosedRange(4, 6));
+```
+
+would generate a failure that contains the text:
+
+```shell
+ Expected: in closed range (4, 6)
+```
+
+For the purpose of typing, you can view
+
+```cpp
+MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+```
+
+as shorthand for
+
+```cpp
+template <typename p1_type, ..., typename pk_type>
+FooMatcherPk<p1_type, ..., pk_type>
+Foo(p1_type p1, ..., pk_type pk) { ... }
+```
+
+When you write `Foo(v1, ..., vk)`, the compiler infers the types of the
+parameters `v1`, ..., and `vk` for you. If you are not happy with the result of
+the type inference, you can specify the types by explicitly instantiating the
+template, as in `Foo<long, bool>(5, false)`. As said earlier, you don't get to
+(or need to) specify `arg_type` as that's determined by the context in which the
+matcher is used.
+
+You can assign the result of expression `Foo(p1, ..., pk)` to a variable of type
+`FooMatcherPk<p1_type, ..., pk_type>`. This can be useful when composing
+matchers. Matchers that don't have a parameter or have only one parameter have
+special types: you can assign `Foo()` to a `FooMatcher`-typed variable, and
+assign `Foo(p)` to a `FooMatcherP<p_type>`-typed variable.
+
+While you can instantiate a matcher template with reference types, passing the
+parameters by pointer usually makes your code more readable. If, however, you
+still want to pass a parameter by reference, be aware that in the failure
+message generated by the matcher you will see the value of the referenced object
+but not its address.
+
+You can overload matchers with different numbers of parameters:
+
+```cpp
+MATCHER_P(Blah, a, description_string_1) { ... }
+MATCHER_P2(Blah, a, b, description_string_2) { ... }
+```
+
+While it's tempting to always use the `MATCHER*` macros when defining a new
+matcher, you should also consider implementing `MatcherInterface` or using
+`MakePolymorphicMatcher()` instead (see the recipes that follow), especially if
+you need to use the matcher a lot. While these approaches require more work,
+they give you more control on the types of the value being matched and the
+matcher parameters, which in general leads to better compiler error messages
+that pay off in the long run. They also allow overloading matchers based on
+parameter types (as opposed to just based on the number of parameters).
+
+### Writing New Monomorphic Matchers
+
+A matcher of argument type `T` implements `::testing::MatcherInterface<T>` and
+does two things: it tests whether a value of type `T` matches the matcher, and
+can describe what kind of values it matches. The latter ability is used for
+generating readable error messages when expectations are violated.
+
+The interface looks like this:
+
+```cpp
+class MatchResultListener {
+ public:
+ ...
+ // Streams x to the underlying ostream; does nothing if the ostream
+ // is NULL.
+ template <typename T>
+ MatchResultListener& operator<<(const T& x);
+
+ // Returns the underlying ostream.
+ std::ostream* stream();
+};
+
+template <typename T>
+class MatcherInterface {
+ public:
+ virtual ~MatcherInterface();
+
+ // Returns true if and only if the matcher matches x; also explains the match
+ // result to 'listener'.
+ virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0;
+
+ // Describes this matcher to an ostream.
+ virtual void DescribeTo(std::ostream* os) const = 0;
+
+ // Describes the negation of this matcher to an ostream.
+ virtual void DescribeNegationTo(std::ostream* os) const;
+};
+```
+
+If you need a custom matcher but `Truly()` is not a good option (for example,
+you may not be happy with the way `Truly(predicate)` describes itself, or you
+may want your matcher to be polymorphic as `Eq(value)` is), you can define a
+matcher to do whatever you want in two steps: first implement the matcher
+interface, and then define a factory function to create a matcher instance. The
+second step is not strictly needed but it makes the syntax of using the matcher
+nicer.
+
+For example, you can define a matcher to test whether an `int` is divisible by 7
+and then use it like this:
+
+```cpp
+using ::testing::MakeMatcher;
+using ::testing::Matcher;
+using ::testing::MatcherInterface;
+using ::testing::MatchResultListener;
+
+class DivisibleBy7Matcher : public MatcherInterface<int> {
+ public:
+ bool MatchAndExplain(int n,
+ MatchResultListener* /* listener */) const override {
+ return (n % 7) == 0;
+ }
+
+ void DescribeTo(std::ostream* os) const override {
+ *os << "is divisible by 7";
+ }
+
+ void DescribeNegationTo(std::ostream* os) const override {
+ *os << "is not divisible by 7";
+ }
+};
+
+Matcher<int> DivisibleBy7() {
+ return MakeMatcher(new DivisibleBy7Matcher);
+}
+
+...
+ EXPECT_CALL(foo, Bar(DivisibleBy7()));
+```
+
+You may improve the matcher message by streaming additional information to the
+`listener` argument in `MatchAndExplain()`:
+
+```cpp
+class DivisibleBy7Matcher : public MatcherInterface<int> {
+ public:
+ bool MatchAndExplain(int n,
+ MatchResultListener* listener) const override {
+ const int remainder = n % 7;
+ if (remainder != 0) {
+ *listener << "the remainder is " << remainder;
+ }
+ return remainder == 0;
+ }
+ ...
+};
+```
+
+Then, `EXPECT_THAT(x, DivisibleBy7());` may generate a message like this:
+
+```shell
+Value of: x
+Expected: is divisible by 7
+ Actual: 23 (the remainder is 2)
+```
+
+### Writing New Polymorphic Matchers
+
+You've learned how to write your own matchers in the previous recipe. Just one
+problem: a matcher created using `MakeMatcher()` only works for one particular
+type of arguments. If you want a *polymorphic* matcher that works with arguments
+of several types (for instance, `Eq(x)` can be used to match a *`value`* as long
+as `value == x` compiles -- *`value`* and `x` don't have to share the same
+type), you can learn the trick from `testing/base/public/gmock-matchers.h` but
+it's a bit involved.
+
+Fortunately, most of the time you can define a polymorphic matcher easily with
+the help of `MakePolymorphicMatcher()`. Here's how you can define `NotNull()` as
+an example:
+
+```cpp
+using ::testing::MakePolymorphicMatcher;
+using ::testing::MatchResultListener;
+using ::testing::PolymorphicMatcher;
+
+class NotNullMatcher {
+ public:
+ // To implement a polymorphic matcher, first define a COPYABLE class
+ // that has three members MatchAndExplain(), DescribeTo(), and
+ // DescribeNegationTo(), like the following.
+
+ // In this example, we want to use NotNull() with any pointer, so
+ // MatchAndExplain() accepts a pointer of any type as its first argument.
+ // In general, you can define MatchAndExplain() as an ordinary method or
+ // a method template, or even overload it.
+ template <typename T>
+ bool MatchAndExplain(T* p,
+ MatchResultListener* /* listener */) const {
+ return p != NULL;
+ }
+
+ // Describes the property of a value matching this matcher.
+ void DescribeTo(std::ostream* os) const { *os << "is not NULL"; }
+
+ // Describes the property of a value NOT matching this matcher.
+ void DescribeNegationTo(std::ostream* os) const { *os << "is NULL"; }
+};
+
+// To construct a polymorphic matcher, pass an instance of the class
+// to MakePolymorphicMatcher(). Note the return type.
+PolymorphicMatcher<NotNullMatcher> NotNull() {
+ return MakePolymorphicMatcher(NotNullMatcher());
+}
+
+...
+
+ EXPECT_CALL(foo, Bar(NotNull())); // The argument must be a non-NULL pointer.
+```
+
+**Note:** Your polymorphic matcher class does **not** need to inherit from
+`MatcherInterface` or any other class, and its methods do **not** need to be
+virtual.
+
+Like in a monomorphic matcher, you may explain the match result by streaming
+additional information to the `listener` argument in `MatchAndExplain()`.
+
+### Writing New Cardinalities
+
+A cardinality is used in `Times()` to tell gMock how many times you expect a
+call to occur. It doesn't have to be exact. For example, you can say
+`AtLeast(5)` or `Between(2, 4)`.
+
+If the [built-in set](cheat_sheet.md#CardinalityList) of cardinalities doesn't
+suit you, you are free to define your own by implementing the following
+interface (in namespace `testing`):
+
+```cpp
+class CardinalityInterface {
+ public:
+ virtual ~CardinalityInterface();
+
+ // Returns true if and only if call_count calls will satisfy this cardinality.
+ virtual bool IsSatisfiedByCallCount(int call_count) const = 0;
+
+ // Returns true if and only if call_count calls will saturate this
+ // cardinality.
+ virtual bool IsSaturatedByCallCount(int call_count) const = 0;
+
+ // Describes self to an ostream.
+ virtual void DescribeTo(std::ostream* os) const = 0;
+};
+```
+
+For example, to specify that a call must occur even number of times, you can
+write
+
+```cpp
+using ::testing::Cardinality;
+using ::testing::CardinalityInterface;
+using ::testing::MakeCardinality;
+
+class EvenNumberCardinality : public CardinalityInterface {
+ public:
+ bool IsSatisfiedByCallCount(int call_count) const override {
+ return (call_count % 2) == 0;
+ }
+
+ bool IsSaturatedByCallCount(int call_count) const override {
+ return false;
+ }
+
+ void DescribeTo(std::ostream* os) const {
+ *os << "called even number of times";
+ }
+};
+
+Cardinality EvenNumber() {
+ return MakeCardinality(new EvenNumberCardinality);
+}
+
+...
+ EXPECT_CALL(foo, Bar(3))
+ .Times(EvenNumber());
+```
+
+### Writing New Actions Quickly {#QuickNewActions}
+
+If the built-in actions don't work for you, you can easily define your own one.
+Just define a functor class with a (possibly templated) call operator, matching
+the signature of your action.
+
+```cpp
+struct Increment {
+ template <typename T>
+ T operator()(T* arg) {
+ return ++(*arg);
+ }
+}
+```
+
+The same approach works with stateful functors (or any callable, really):
+
+```
+struct MultiplyBy {
+ template <typename T>
+ T operator()(T arg) { return arg * multiplier; }
+
+ int multiplier;
+}
+
+// Then use:
+// EXPECT_CALL(...).WillOnce(MultiplyBy{7});
+```
+
+#### Legacy macro-based Actions
+
+Before C++11, the functor-based actions were not supported; the old way of
+writing actions was through a set of `ACTION*` macros. We suggest to avoid them
+in new code; they hide a lot of logic behind the macro, potentially leading to
+harder-to-understand compiler errors. Nevertheless, we cover them here for
+completeness.
+
+By writing
+
+```cpp
+ACTION(name) { statements; }
+```
+
+in a namespace scope (i.e. not inside a class or function), you will define an
+action with the given name that executes the statements. The value returned by
+`statements` will be used as the return value of the action. Inside the
+statements, you can refer to the K-th (0-based) argument of the mock function as
+`argK`. For example:
+
+```cpp
+ACTION(IncrementArg1) { return ++(*arg1); }
+```
+
+allows you to write
+
+```cpp
+... WillOnce(IncrementArg1());
+```
+
+Note that you don't need to specify the types of the mock function arguments.
+Rest assured that your code is type-safe though: you'll get a compiler error if
+`*arg1` doesn't support the `++` operator, or if the type of `++(*arg1)` isn't
+compatible with the mock function's return type.
+
+Another example:
+
+```cpp
+ACTION(Foo) {
+ (*arg2)(5);
+ Blah();
+ *arg1 = 0;
+ return arg0;
+}
+```
+
+defines an action `Foo()` that invokes argument #2 (a function pointer) with 5,
+calls function `Blah()`, sets the value pointed to by argument #1 to 0, and
+returns argument #0.
+
+For more convenience and flexibility, you can also use the following pre-defined
+symbols in the body of `ACTION`:
+
+`argK_type` | The type of the K-th (0-based) argument of the mock function
+:-------------- | :-----------------------------------------------------------
+`args` | All arguments of the mock function as a tuple
+`args_type` | The type of all arguments of the mock function as a tuple
+`return_type` | The return type of the mock function
+`function_type` | The type of the mock function
+
+For example, when using an `ACTION` as a stub action for mock function:
+
+```cpp
+int DoSomething(bool flag, int* ptr);
+```
+
+we have:
+
+Pre-defined Symbol | Is Bound To
+------------------ | ---------------------------------
+`arg0` | the value of `flag`
+`arg0_type` | the type `bool`
+`arg1` | the value of `ptr`
+`arg1_type` | the type `int*`
+`args` | the tuple `(flag, ptr)`
+`args_type` | the type `std::tuple<bool, int*>`
+`return_type` | the type `int`
+`function_type` | the type `int(bool, int*)`
+
+#### Legacy macro-based parameterized Actions
+
+Sometimes you'll want to parameterize an action you define. For that we have
+another macro
+
+```cpp
+ACTION_P(name, param) { statements; }
+```
+
+For example,
+
+```cpp
+ACTION_P(Add, n) { return arg0 + n; }
+```
+
+will allow you to write
+
+```cpp
+// Returns argument #0 + 5.
+... WillOnce(Add(5));
+```
+
+For convenience, we use the term *arguments* for the values used to invoke the
+mock function, and the term *parameters* for the values used to instantiate an
+action.
+
+Note that you don't need to provide the type of the parameter either. Suppose
+the parameter is named `param`, you can also use the gMock-defined symbol
+`param_type` to refer to the type of the parameter as inferred by the compiler.
+For example, in the body of `ACTION_P(Add, n)` above, you can write `n_type` for
+the type of `n`.
+
+gMock also provides `ACTION_P2`, `ACTION_P3`, and etc to support multi-parameter
+actions. For example,
+
+```cpp
+ACTION_P2(ReturnDistanceTo, x, y) {
+ double dx = arg0 - x;
+ double dy = arg1 - y;
+ return sqrt(dx*dx + dy*dy);
+}
+```
+
+lets you write
+
+```cpp
+... WillOnce(ReturnDistanceTo(5.0, 26.5));
+```
+
+You can view `ACTION` as a degenerated parameterized action where the number of
+parameters is 0.
+
+You can also easily define actions overloaded on the number of parameters:
+
+```cpp
+ACTION_P(Plus, a) { ... }
+ACTION_P2(Plus, a, b) { ... }
+```
+
+### Restricting the Type of an Argument or Parameter in an ACTION
+
+For maximum brevity and reusability, the `ACTION*` macros don't ask you to
+provide the types of the mock function arguments and the action parameters.
+Instead, we let the compiler infer the types for us.
+
+Sometimes, however, we may want to be more explicit about the types. There are
+several tricks to do that. For example:
+
+```cpp
+ACTION(Foo) {
+ // Makes sure arg0 can be converted to int.
+ int n = arg0;
+ ... use n instead of arg0 here ...
+}
+
+ACTION_P(Bar, param) {
+ // Makes sure the type of arg1 is const char*.
+ ::testing::StaticAssertTypeEq<const char*, arg1_type>();
+
+ // Makes sure param can be converted to bool.
+ bool flag = param;
+}
+```
+
+where `StaticAssertTypeEq` is a compile-time assertion in googletest that
+verifies two types are the same.
+
+### Writing New Action Templates Quickly
+
+Sometimes you want to give an action explicit template parameters that cannot be
+inferred from its value parameters. `ACTION_TEMPLATE()` supports that and can be
+viewed as an extension to `ACTION()` and `ACTION_P*()`.
+
+The syntax:
+
+```cpp
+ACTION_TEMPLATE(ActionName,
+ HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+ AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+```
+
+defines an action template that takes *m* explicit template parameters and *n*
+value parameters, where *m* is in [1, 10] and *n* is in [0, 10]. `name_i` is the
+name of the *i*-th template parameter, and `kind_i` specifies whether it's a
+`typename`, an integral constant, or a template. `p_i` is the name of the *i*-th
+value parameter.
+
+Example:
+
+```cpp
+// DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// function to type T and copies it to *output.
+ACTION_TEMPLATE(DuplicateArg,
+ // Note the comma between int and k:
+ HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+ AND_1_VALUE_PARAMS(output)) {
+ *output = T(std::get<k>(args));
+}
+```
+
+To create an instance of an action template, write:
+
+```cpp
+ActionName<t1, ..., t_m>(v1, ..., v_n)
+```
+
+where the `t`s are the template arguments and the `v`s are the value arguments.
+The value argument types are inferred by the compiler. For example:
+
+```cpp
+using ::testing::_;
+...
+ int n;
+ EXPECT_CALL(mock, Foo).WillOnce(DuplicateArg<1, unsigned char>(&n));
+```
+
+If you want to explicitly specify the value argument types, you can provide
+additional template arguments:
+
+```cpp
+ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+```
+
+where `u_i` is the desired type of `v_i`.
+
+`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the number of
+value parameters, but not on the number of template parameters. Without the
+restriction, the meaning of the following is unclear:
+
+```cpp
+ OverloadedAction<int, bool>(x);
+```
+
+Are we using a single-template-parameter action where `bool` refers to the type
+of `x`, or a two-template-parameter action where the compiler is asked to infer
+the type of `x`?
+
+### Using the ACTION Object's Type
+
+If you are writing a function that returns an `ACTION` object, you'll need to
+know its type. The type depends on the macro used to define the action and the
+parameter types. The rule is relatively simple:
+
+| Given Definition | Expression | Has Type |
+| ----------------------------- | ------------------- | --------------------- |
+| `ACTION(Foo)` | `Foo()` | `FooAction` |
+| `ACTION_TEMPLATE(Foo,` | `Foo<t1, ..., | `FooAction<t1, ..., |
+: `HAS_m_TEMPLATE_PARAMS(...),` : t_m>()` : t_m>` :
+: `AND_0_VALUE_PARAMS())` : : :
+| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
+| `ACTION_TEMPLATE(Bar,` | `Bar<t1, ..., t_m>` | `FooActionP<t1, ..., |
+: `HAS_m_TEMPLATE_PARAMS(...),` : `(int_value)` : t_m, int>` :
+: `AND_1_VALUE_PARAMS(p1))` : : :
+| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value,` | `BazActionP2<bool, |
+: : `int_value)` : int>` :
+| `ACTION_TEMPLATE(Baz,` | `Baz<t1, ..., t_m>` | `FooActionP2<t1, ..., |
+: `HAS_m_TEMPLATE_PARAMS(...),` : `(bool_value,` : t_m,` `bool, int>` :
+: `AND_2_VALUE_PARAMS(p1, p2))` : `int_value)` : :
+| ... | ... | ... |
+
+Note that we have to pick different suffixes (`Action`, `ActionP`, `ActionP2`,
+and etc) for actions with different numbers of value parameters, or the action
+definitions cannot be overloaded on the number of them.
+
+### Writing New Monomorphic Actions {#NewMonoActions}
+
+While the `ACTION*` macros are very convenient, sometimes they are
+inappropriate. For example, despite the tricks shown in the previous recipes,
+they don't let you directly specify the types of the mock function arguments and
+the action parameters, which in general leads to unoptimized compiler error
+messages that can baffle unfamiliar users. They also don't allow overloading
+actions based on parameter types without jumping through some hoops.
+
+An alternative to the `ACTION*` macros is to implement
+`::testing::ActionInterface<F>`, where `F` is the type of the mock function in
+which the action will be used. For example:
+
+```cpp
+template <typename F>
+class ActionInterface {
+ public:
+ virtual ~ActionInterface();
+
+ // Performs the action. Result is the return type of function type
+ // F, and ArgumentTuple is the tuple of arguments of F.
+ //
+
+ // For example, if F is int(bool, const string&), then Result would
+ // be int, and ArgumentTuple would be std::tuple<bool, const string&>.
+ virtual Result Perform(const ArgumentTuple& args) = 0;
+};
+```
+
+```cpp
+using ::testing::_;
+using ::testing::Action;
+using ::testing::ActionInterface;
+using ::testing::MakeAction;
+
+typedef int IncrementMethod(int*);
+
+class IncrementArgumentAction : public ActionInterface<IncrementMethod> {
+ public:
+ int Perform(const std::tuple<int*>& args) override {
+ int* p = std::get<0>(args); // Grabs the first argument.
+ return *p++;
+ }
+};
+
+Action<IncrementMethod> IncrementArgument() {
+ return MakeAction(new IncrementArgumentAction);
+}
+
+...
+ EXPECT_CALL(foo, Baz(_))
+ .WillOnce(IncrementArgument());
+
+ int n = 5;
+ foo.Baz(&n); // Should return 5 and change n to 6.
+```
+
+### Writing New Polymorphic Actions {#NewPolyActions}
+
+The previous recipe showed you how to define your own action. This is all good,
+except that you need to know the type of the function in which the action will
+be used. Sometimes that can be a problem. For example, if you want to use the
+action in functions with *different* types (e.g. like `Return()` and
+`SetArgPointee()`).
+
+If an action can be used in several types of mock functions, we say it's
+*polymorphic*. The `MakePolymorphicAction()` function template makes it easy to
+define such an action:
+
+```cpp
+namespace testing {
+template <typename Impl>
+PolymorphicAction<Impl> MakePolymorphicAction(const Impl& impl);
+} // namespace testing
+```
+
+As an example, let's define an action that returns the second argument in the
+mock function's argument list. The first step is to define an implementation
+class:
+
+```cpp
+class ReturnSecondArgumentAction {
+ public:
+ template <typename Result, typename ArgumentTuple>
+ Result Perform(const ArgumentTuple& args) const {
+ // To get the i-th (0-based) argument, use std::get(args).
+ return std::get<1>(args);
+ }
+};
+```
+
+This implementation class does *not* need to inherit from any particular class.
+What matters is that it must have a `Perform()` method template. This method
+template takes the mock function's arguments as a tuple in a **single**
+argument, and returns the result of the action. It can be either `const` or not,
+but must be invokable with exactly one template argument, which is the result
+type. In other words, you must be able to call `Perform<R>(args)` where `R` is
+the mock function's return type and `args` is its arguments in a tuple.
+
+Next, we use `MakePolymorphicAction()` to turn an instance of the implementation
+class into the polymorphic action we need. It will be convenient to have a
+wrapper for this:
+
+```cpp
+using ::testing::MakePolymorphicAction;
+using ::testing::PolymorphicAction;
+
+PolymorphicAction<ReturnSecondArgumentAction> ReturnSecondArgument() {
+ return MakePolymorphicAction(ReturnSecondArgumentAction());
+}
+```
+
+Now, you can use this polymorphic action the same way you use the built-in ones:
+
+```cpp
+using ::testing::_;
+
+class MockFoo : public Foo {
+ public:
+ MOCK_METHOD(int, DoThis, (bool flag, int n), (override));
+ MOCK_METHOD(string, DoThat, (int x, const char* str1, const char* str2),
+ (override));
+};
+
+ ...
+ MockFoo foo;
+ EXPECT_CALL(foo, DoThis).WillOnce(ReturnSecondArgument());
+ EXPECT_CALL(foo, DoThat).WillOnce(ReturnSecondArgument());
+ ...
+ foo.DoThis(true, 5); // Will return 5.
+ foo.DoThat(1, "Hi", "Bye"); // Will return "Hi".
+```
+
+### Teaching gMock How to Print Your Values
+
+When an uninteresting or unexpected call occurs, gMock prints the argument
+values and the stack trace to help you debug. Assertion macros like
+`EXPECT_THAT` and `EXPECT_EQ` also print the values in question when the
+assertion fails. gMock and googletest do this using googletest's user-extensible
+value printer.
+
+This printer knows how to print built-in C++ types, native arrays, STL
+containers, and any type that supports the `<<` operator. For other types, it
+prints the raw bytes in the value and hopes that you the user can figure it out.
+[googletest's advanced guide](../../googletest/docs/advanced.md#teaching-googletest-how-to-print-your-values)
+explains how to extend the printer to do a better job at printing your
+particular type than to dump the bytes.

+

+<!--#include file="includes/g3_mock_callbacks.md"-->
+
+### Mock std::function {#MockFunction}
+
+`std::function` is a general function type introduced in C++11. It is a
+preferred way of passing callbacks to new interfaces. Functions are copiable,
+and are not usually passed around by pointer, which makes them tricky to mock.
+But fear not - `MockFunction` can help you with that.
+
+`MockFunction<R(T1, ..., Tn)>` has a mock method `Call()` with the signature:
+
+```cpp
+ R Call(T1, ..., Tn);
+```
+
+It also has a `AsStdFunction()` method, which creates a `std::function` proxy
+forwarding to Call:
+
+```cpp
+ std::function<R(T1, ..., Tn)> AsStdFunction();
+```
+
+To use `MockFunction`, first create `MockFunction` object and set up
+expectations on its `Call` method. Then pass proxy obtained from
+`AsStdFunction()` to the code you are testing. For example:
+
+```cpp
+TEST(FooTest, RunsCallbackWithBarArgument) {
+ // 1. Create a mock object.
+ MockFunction<int(string)> mock_function;
+
+ // 2. Set expectations on Call() method.
+ EXPECT_CALL(mock_function, Call("bar")).WillOnce(Return(1));
+
+ // 3. Exercise code that uses std::function.
+ Foo(mock_function.AsStdFunction());
+ // Foo's signature can be either of:
+ // void Foo(const std::function<int(string)>& fun);
+ // void Foo(std::function<int(string)> fun);
+
+ // 4. All expectations will be verified when mock_function
+ // goes out of scope and is destroyed.
+}
+```
+
+Remember that function objects created with `AsStdFunction()` are just
+forwarders. If you create multiple of them, they will share the same set of
+expectations.
+
+Although `std::function` supports unlimited number of arguments, `MockFunction`
+implementation is limited to ten. If you ever hit that limit... well, your
+callback has bigger problems than being mockable. :-)

+
+## What Is gMock?
+
+When you write a prototype or test, often it's not feasible or wise to rely on
+real objects entirely. A **mock object** implements the same interface as a real
+object (so it can be used as one), but lets you specify at run time how it will
+be used and what it should do (which methods will be called? in which order? how
+many times? with what arguments? what will they return? etc).
+
+**Note:** It is easy to confuse the term *fake objects* with mock objects. Fakes
+and mocks actually mean very different things in the Test-Driven Development
+(TDD) community:
+
+* **Fake** objects have working implementations, but usually take some
+ shortcut (perhaps to make the operations less expensive), which makes them
+ not suitable for production. An in-memory file system would be an example of
+ a fake.
+* **Mocks** are objects pre-programmed with *expectations*, which form a
+ specification of the calls they are expected to receive.
+
+If all this seems too abstract for you, don't worry - the most important thing
+to remember is that a mock allows you to check the *interaction* between itself
+and code that uses it. The difference between fakes and mocks shall become much
+clearer once you start to use mocks.
+
+**gMock** is a library (sometimes we also call it a "framework" to make it sound
+cool) for creating mock classes and using them. It does to C++ what
+jMock/EasyMock does to Java (well, more or less).
+
+When using gMock,
+
+1. first, you use some simple macros to describe the interface you want to
+ mock, and they will expand to the implementation of your mock class;
+2. next, you create some mock objects and specify its expectations and behavior
+ using an intuitive syntax;
+3. then you exercise code that uses the mock objects. gMock will catch any
+ violation to the expectations as soon as it arises.
+
+## Why gMock?
+
+While mock objects help you remove unnecessary dependencies in tests and make
+them fast and reliable, using mocks manually in C++ is *hard*:
+
+* Someone has to implement the mocks. The job is usually tedious and
+ error-prone. No wonder people go great distance to avoid it.
+* The quality of those manually written mocks is a bit, uh, unpredictable. You
+ may see some really polished ones, but you may also see some that were
+ hacked up in a hurry and have all sorts of ad hoc restrictions.
+* The knowledge you gained from using one mock doesn't transfer to the next
+ one.
+
+In contrast, Java and Python programmers have some fine mock frameworks (jMock,
+EasyMock, [Mox](http://wtf/mox), etc), which automate the creation of mocks. As
+a result, mocking is a proven effective technique and widely adopted practice in
+those communities. Having the right tool absolutely makes the difference.
+
+gMock was built to help C++ programmers. It was inspired by jMock and EasyMock,
+but designed with C++'s specifics in mind. It is your friend if any of the
+following problems is bothering you:
+
+* You are stuck with a sub-optimal design and wish you had done more
+ prototyping before it was too late, but prototyping in C++ is by no means
+ "rapid".
+* Your tests are slow as they depend on too many libraries or use expensive
+ resources (e.g. a database).
+* Your tests are brittle as some resources they use are unreliable (e.g. the
+ network).
+* You want to test how your code handles a failure (e.g. a file checksum
+ error), but it's not easy to cause one.
+* You need to make sure that your module interacts with other modules in the
+ right way, but it's hard to observe the interaction; therefore you resort to
+ observing the side effects at the end of the action, but it's awkward at
+ best.
+* You want to "mock out" your dependencies, except that they don't have mock
+ implementations yet; and, frankly, you aren't thrilled by some of those
+ hand-written mocks.
+
+We encourage you to use gMock as
+
+* a *design* tool, for it lets you experiment with your interface design early
+ and often. More iterations lead to better designs!
+* a *testing* tool to cut your tests' outbound dependencies and probe the
+ interaction between your module and its collaborators.
+
+## Getting Started
+
+gMock is bundled with googletest.
+
+## A Case for Mock Turtles
+
+Let's look at an example. Suppose you are developing a graphics program that
+relies on a [LOGO](http://en.wikipedia.org/wiki/Logo_programming_language)-like
+API for drawing. How would you test that it does the right thing? Well, you can
+run it and compare the screen with a golden screen snapshot, but let's admit it:
+tests like this are expensive to run and fragile (What if you just upgraded to a
+shiny new graphics card that has better anti-aliasing? Suddenly you have to
+update all your golden images.). It would be too painful if all your tests are
+like this. Fortunately, you learned about
+[Dependency Injection](http://en.wikipedia.org/wiki/Dependency_injection) and know the right thing
+to do: instead of having your application talk to the system API directly, wrap
+the API in an interface (say, `Turtle`) and code to that interface:
+
+```cpp
+class Turtle {
+ ...
+ virtual ~Turtle() {}
+ virtual void PenUp() = 0;
+ virtual void PenDown() = 0;
+ virtual void Forward(int distance) = 0;
+ virtual void Turn(int degrees) = 0;
+ virtual void GoTo(int x, int y) = 0;
+ virtual int GetX() const = 0;
+ virtual int GetY() const = 0;
+};
+```
+
+(Note that the destructor of `Turtle` **must** be virtual, as is the case for
+**all** classes you intend to inherit from - otherwise the destructor of the
+derived class will not be called when you delete an object through a base
+pointer, and you'll get corrupted program states like memory leaks.)
+
+You can control whether the turtle's movement will leave a trace using `PenUp()`
+and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and
+`GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the
+turtle.
+
+Your program will normally use a real implementation of this interface. In
+tests, you can use a mock implementation instead. This allows you to easily
+check what drawing primitives your program is calling, with what arguments, and
+in which order. Tests written this way are much more robust (they won't break
+because your new machine does anti-aliasing differently), easier to read and
+maintain (the intent of a test is expressed in the code, not in some binary
+images), and run *much, much faster*.
+
+## Writing the Mock Class
+
+If you are lucky, the mocks you need to use have already been implemented by
+some nice people. If, however, you find yourself in the position to write a mock
+class, relax - gMock turns this task into a fun game! (Well, almost.)
+
+### How to Define It
+
+Using the `Turtle` interface as example, here are the simple steps you need to
+follow:
+
+* Derive a class `MockTurtle` from `Turtle`.
+* Take a *virtual* function of `Turtle` (while it's possible to
+ [mock non-virtual methods using templates](cook_book.md#MockingNonVirtualMethods),
+ it's much more involved).
+* In the `public:` section of the child class, write `MOCK_METHOD();`
+* Now comes the fun part: you take the function signature, cut-and-paste it
+ into the macro, and add two commas - one between the return type and the
+ name, another between the name and the argument list.
+* If you're mocking a const method, add a 4th parameter containing `(const)`
+ (the parentheses are required).
+* Since you're overriding a virtual method, we suggest adding the `override`
+ keyword. For const methods the 4th parameter becomes `(const, override)`,
+ for non-const methods just `(override)`. This isn't mandatory.
+* Repeat until all virtual functions you want to mock are done. (It goes
+ without saying that *all* pure virtual methods in your abstract class must
+ be either mocked or overridden.)
+
+After the process, you should have something like:
+
+```cpp
+#include "gmock/gmock.h" // Brings in gMock.
+
+class MockTurtle : public Turtle {
+ public:
+ ...
+ MOCK_METHOD(void, PenUp, (), (override));
+ MOCK_METHOD(void, PenDown, (), (override));
+ MOCK_METHOD(void, Forward, (int distance), (override));
+ MOCK_METHOD(void, Turn, (int degrees), (override));
+ MOCK_METHOD(void, GoTo, (int x, int y), (override));
+ MOCK_METHOD(int, GetX, (), (const, override));
+ MOCK_METHOD(int, GetY, (), (const, override));
+};
+```
+
+You don't need to define these mock methods somewhere else - the `MOCK_METHOD`
+macro will generate the definitions for you. It's that simple!
+
+### Where to Put It
+
+When you define a mock class, you need to decide where to put its definition.
+Some people put it in a `_test.cc`. This is fine when the interface being mocked
+(say, `Foo`) is owned by the same person or team. Otherwise, when the owner of
+`Foo` changes it, your test could break. (You can't really expect `Foo`'s
+maintainer to fix every test that uses `Foo`, can you?)
+
+So, the rule of thumb is: if you need to mock `Foo` and it's owned by others,
+define the mock class in `Foo`'s package (better, in a `testing` sub-package
+such that you can clearly separate production code and testing utilities), put
+it in a `.h` and a `cc_library`. Then everyone can reference them from their
+tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and
+only tests that depend on the changed methods need to be fixed.
+
+Another way to do it: you can introduce a thin layer `FooAdaptor` on top of
+`Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb
+changes in `Foo` much more easily. While this is more work initially, carefully
+choosing the adaptor interface can make your code easier to write and more
+readable (a net win in the long run), as you can choose `FooAdaptor` to fit your
+specific domain much better than `Foo` does.
+
+<!-- GOOGLETEST_CM0029 DO NOT DELETE -->
+
+## Using Mocks in Tests
+
+Once you have a mock class, using it is easy. The typical work flow is:
+
+1. Import the gMock names from the `testing` namespace such that you can use
+ them unqualified (You only have to do it once per file). Remember that
+ namespaces are a good idea.
+2. Create some mock objects.
+3. Specify your expectations on them (How many times will a method be called?
+ With what arguments? What should it do? etc.).
+4. Exercise some code that uses the mocks; optionally, check the result using
+ googletest assertions. If a mock method is called more than expected or with
+ wrong arguments, you'll get an error immediately.
+5. When a mock is destructed, gMock will automatically check whether all
+ expectations on it have been satisfied.
+
+Here's an example:
+
+```cpp
+#include "path/to/mock-turtle.h"
+#include "gmock/gmock.h"
+#include "gtest/gtest.h"
+
+using ::testing::AtLeast; // #1
+
+TEST(PainterTest, CanDrawSomething) {
+ MockTurtle turtle; // #2
+ EXPECT_CALL(turtle, PenDown()) // #3
+ .Times(AtLeast(1));
+
+ Painter painter(&turtle); // #4
+
+ EXPECT_TRUE(painter.DrawCircle(0, 0, 10)); // #5
+}
+```
+
+As you might have guessed, this test checks that `PenDown()` is called at least
+once. If the `painter` object didn't call this method, your test will fail with
+a message like this:
+
+```text
+path/to/my_test.cc:119: Failure
+Actual function call count doesn't match this expectation:
+Actually: never called;
+Expected: called at least once.
+Stack trace:
+...
+```
+
+**Tip 1:** If you run the test from an Emacs buffer, you can hit `<Enter>` on
+the line number to jump right to the failed expectation.
+
+**Tip 2:** If your mock objects are never deleted, the final verification won't
+happen. Therefore it's a good idea to turn on the heap checker in your tests
+when you allocate mocks on the heap. You get that automatically if you use the
+`gtest_main` library already.
+
+**Important note:** gMock requires expectations to be set **before** the mock
+functions are called, otherwise the behavior is **undefined**. In particular,
+you mustn't interleave `EXPECT_CALL()s` and calls to the mock functions.
+
+This means `EXPECT_CALL()` should be read as expecting that a call will occur
+*in the future*, not that a call has occurred. Why does gMock work like that?
+Well, specifying the expectation beforehand allows gMock to report a violation
+as soon as it rises, when the context (stack trace, etc) is still available.
+This makes debugging much easier.
+
+Admittedly, this test is contrived and doesn't do much. You can easily achieve
+the same effect without using gMock. However, as we shall reveal soon, gMock
+allows you to do *so much more* with the mocks.
+
+## Setting Expectations
+
+The key to using a mock object successfully is to set the *right expectations*
+on it. If you set the expectations too strict, your test will fail as the result
+of unrelated changes. If you set them too loose, bugs can slip through. You want
+to do it just right such that your test can catch exactly the kind of bugs you
+intend it to catch. gMock provides the necessary means for you to do it "just
+right."
+
+### General Syntax
+
+In gMock we use the `EXPECT_CALL()` macro to set an expectation on a mock
+method. The general syntax is:
+
+```cpp
+EXPECT_CALL(mock_object, method(matchers))
+ .Times(cardinality)
+ .WillOnce(action)
+ .WillRepeatedly(action);
+```
+
+The macro has two arguments: first the mock object, and then the method and its
+arguments. Note that the two are separated by a comma (`,`), not a period (`.`).
+(Why using a comma? The answer is that it was necessary for technical reasons.)
+If the method is not overloaded, the macro can also be called without matchers:
+
+```cpp
+EXPECT_CALL(mock_object, non-overloaded-method)
+ .Times(cardinality)
+ .WillOnce(action)
+ .WillRepeatedly(action);
+```
+
+This syntax allows the test writer to specify "called with any arguments"
+without explicitly specifying the number or types of arguments. To avoid
+unintended ambiguity, this syntax may only be used for methods which are not
+overloaded
+
+Either form of the macro can be followed by some optional *clauses* that provide
+more information about the expectation. We'll discuss how each clause works in
+the coming sections.
+
+This syntax is designed to make an expectation read like English. For example,
+you can probably guess that
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .Times(5)
+ .WillOnce(Return(100))
+ .WillOnce(Return(150))
+ .WillRepeatedly(Return(200));
+```
+
+says that the `turtle` object's `GetX()` method will be called five times, it
+will return 100 the first time, 150 the second time, and then 200 every time.
+Some people like to call this style of syntax a Domain-Specific Language (DSL).
+
+**Note:** Why do we use a macro to do this? Well it serves two purposes: first
+it makes expectations easily identifiable (either by `gsearch` or by a human
+reader), and second it allows gMock to include the source file location of a
+failed expectation in messages, making debugging easier.
+
+### Matchers: What Arguments Do We Expect?
+
+When a mock function takes arguments, we may specify what arguments we are
+expecting, for example:
+
+```cpp
+// Expects the turtle to move forward by 100 units.
+EXPECT_CALL(turtle, Forward(100));
+```
+
+Oftentimes you do not want to be too specific. Remember that talk about tests
+being too rigid? Over specification leads to brittle tests and obscures the
+intent of tests. Therefore we encourage you to specify only what's necessary—no
+more, no less. If you aren't interested in the value of an argument, write `_`
+as the argument, which means "anything goes":
+
+```cpp
+using ::testing::_;
+...
+// Expects that the turtle jumps to somewhere on the x=50 line.
+EXPECT_CALL(turtle, GoTo(50, _));
+```
+
+`_` is an instance of what we call **matchers**. A matcher is like a predicate
+and can test whether an argument is what we'd expect. You can use a matcher
+inside `EXPECT_CALL()` wherever a function argument is expected. `_` is a
+convenient way of saying "any value".
+
+In the above examples, `100` and `50` are also matchers; implicitly, they are
+the same as `Eq(100)` and `Eq(50)`, which specify that the argument must be
+equal (using `operator==`) to the matcher argument. There are many
+[built-in matchers](cheat_sheet.md#MatcherList) for common types (as well as
+[custom matchers](cook_book.md#NewMatchers)); for example:
+
+```cpp
+using ::testing::Ge;
+...
+// Expects the turtle moves forward by at least 100.
+EXPECT_CALL(turtle, Forward(Ge(100)));
+```
+
+If you don't care about *any* arguments, rather than specify `_` for each of
+them you may instead omit the parameter list:
+
+```cpp
+// Expects the turtle to move forward.
+EXPECT_CALL(turtle, Forward);
+// Expects the turtle to jump somewhere.
+EXPECT_CALL(turtle, GoTo);
+```
+
+This works for all non-overloaded methods; if a method is overloaded, you need
+to help gMock resolve which overload is expected by specifying the number of
+arguments and possibly also the
+[types of the arguments](cook_book.md#SelectOverload).
+
+### Cardinalities: How Many Times Will It Be Called?
+
+The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We
+call its argument a **cardinality** as it tells *how many times* the call should
+occur. It allows us to repeat an expectation many times without actually writing
+it as many times. More importantly, a cardinality can be "fuzzy", just like a
+matcher can be. This allows a user to express the intent of a test exactly.
+
+An interesting special case is when we say `Times(0)`. You may have guessed - it
+means that the function shouldn't be called with the given arguments at all, and
+gMock will report a googletest failure whenever the function is (wrongfully)
+called.
+
+We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the
+list of built-in cardinalities you can use, see
+[here](cheat_sheet.md#CardinalityList).
+
+The `Times()` clause can be omitted. **If you omit `Times()`, gMock will infer
+the cardinality for you.** The rules are easy to remember:
+
+* If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the
+ `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
+* If there are *n* `WillOnce()`'s but **no** `WillRepeatedly()`, where *n* >=
+ 1, the cardinality is `Times(n)`.
+* If there are *n* `WillOnce()`'s and **one** `WillRepeatedly()`, where *n* >=
+ 0, the cardinality is `Times(AtLeast(n))`.
+
+**Quick quiz:** what do you think will happen if a function is expected to be
+called twice but actually called four times?
+
+### Actions: What Should It Do?
+
+Remember that a mock object doesn't really have a working implementation? We as
+users have to tell it what to do when a method is invoked. This is easy in
+gMock.
+
+First, if the return type of a mock function is a built-in type or a pointer,
+the function has a **default action** (a `void` function will just return, a
+`bool` function will return `false`, and other functions will return 0). In
+addition, in C++ 11 and above, a mock function whose return type is
+default-constructible (i.e. has a default constructor) has a default action of
+returning a default-constructed value. If you don't say anything, this behavior
+will be used.
+
+Second, if a mock function doesn't have a default action, or the default action
+doesn't suit you, you can specify the action to be taken each time the
+expectation matches using a series of `WillOnce()` clauses followed by an
+optional `WillRepeatedly()`. For example,
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillOnce(Return(300));
+```
+
+says that `turtle.GetX()` will be called *exactly three times* (gMock inferred
+this from how many `WillOnce()` clauses we've written, since we didn't
+explicitly write `Times()`), and will return 100, 200, and 300 respectively.
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+ .WillOnce(Return(100))
+ .WillOnce(Return(200))
+ .WillRepeatedly(Return(300));
+```
+
+says that `turtle.GetY()` will be called *at least twice* (gMock knows this as
+we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no
+explicit `Times()`), will return 100 and 200 respectively the first two times,
+and 300 from the third time on.
+
+Of course, if you explicitly write a `Times()`, gMock will not try to infer the
+cardinality itself. What if the number you specified is larger than there are
+`WillOnce()` clauses? Well, after all `WillOnce()`s are used up, gMock will do
+the *default* action for the function every time (unless, of course, you have a
+`WillRepeatedly()`.).
+
+What can we do inside `WillOnce()` besides `Return()`? You can return a
+reference using `ReturnRef(*variable*)`, or invoke a pre-defined function, among
+[others](cook_book.md#using-actions).
+
+**Important note:** The `EXPECT_CALL()` statement evaluates the action clause
+only once, even though the action may be performed many times. Therefore you
+must be careful about side effects. The following may not do what you want:
+
+```cpp
+using ::testing::Return;
+...
+int n = 100;
+EXPECT_CALL(turtle, GetX())
+ .Times(4)
+ .WillRepeatedly(Return(n++));
+```
+
+Instead of returning 100, 101, 102, ..., consecutively, this mock function will
+always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)`
+will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will
+return the same pointer every time. If you want the side effect to happen every
+time, you need to define a custom action, which we'll teach in the
+[cook book](http://<!-- GOOGLETEST_CM0012 DO NOT DELETE -->).
+
+Time for another quiz! What do you think the following means?
+
+```cpp
+using ::testing::Return;
+...
+EXPECT_CALL(turtle, GetY())
+ .Times(4)
+ .WillOnce(Return(100));
+```
+
+Obviously `turtle.GetY()` is expected to be called four times. But if you think
+it will return 100 every time, think twice! Remember that one `WillOnce()`
+clause will be consumed each time the function is invoked and the default action
+will be taken afterwards. So the right answer is that `turtle.GetY()` will
+return 100 the first time, but **return 0 from the second time on**, as
+returning 0 is the default action for `int` functions.
+
+### Using Multiple Expectations {#MultiExpectations}
+
+So far we've only shown examples where you have a single expectation. More
+realistically, you'll specify expectations on multiple mock methods which may be
+from multiple mock objects.
+
+By default, when a mock method is invoked, gMock will search the expectations in
+the **reverse order** they are defined, and stop when an active expectation that
+matches the arguments is found (you can think of it as "newer rules override
+older ones."). If the matching expectation cannot take any more calls, you will
+get an upper-bound-violated failure. Here's an example:
+
+```cpp
+using ::testing::_;
+...
+EXPECT_CALL(turtle, Forward(_)); // #1
+EXPECT_CALL(turtle, Forward(10)) // #2
+ .Times(2);
+```
+
+If `Forward(10)` is called three times in a row, the third time it will be an
+error, as the last matching expectation (#2) has been saturated. If, however,
+the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK,
+as now #1 will be the matching expectation.
+
+**Note:** Why does gMock search for a match in the *reverse* order of the
+expectations? The reason is that this allows a user to set up the default
+expectations in a mock object's constructor or the test fixture's set-up phase
+and then customize the mock by writing more specific expectations in the test
+body. So, if you have two expectations on the same method, you want to put the
+one with more specific matchers **after** the other, or the more specific rule
+would be shadowed by the more general one that comes after it.
+
+**Tip:** It is very common to start with a catch-all expectation for a method
+and `Times(AnyNumber())` (omitting arguments, or with `_` for all arguments, if
+overloaded). This makes any calls to the method expected. This is not necessary
+for methods that are not mentioned at all (these are "uninteresting"), but is
+useful for methods that have some expectations, but for which other calls are
+ok. See
+[Understanding Uninteresting vs Unexpected Calls](cook_book.md#uninteresting-vs-unexpected).
+
+### Ordered vs Unordered Calls {#OrderedCalls}
+
+By default, an expectation can match a call even though an earlier expectation
+hasn't been satisfied. In other words, the calls don't have to occur in the
+order the expectations are specified.
+
+Sometimes, you may want all the expected calls to occur in a strict order. To
+say this in gMock is easy:
+
+```cpp
+using ::testing::InSequence;
+...
+TEST(FooTest, DrawsLineSegment) {
+ ...
+ {
+ InSequence seq;
+
+ EXPECT_CALL(turtle, PenDown());
+ EXPECT_CALL(turtle, Forward(100));
+ EXPECT_CALL(turtle, PenUp());
+ }
+ Foo();
+}
+```
+
+By creating an object of type `InSequence`, all expectations in its scope are
+put into a *sequence* and have to occur *sequentially*. Since we are just
+relying on the constructor and destructor of this object to do the actual work,
+its name is really irrelevant.
+
+In this example, we test that `Foo()` calls the three expected functions in the
+order as written. If a call is made out-of-order, it will be an error.
+
+(What if you care about the relative order of some of the calls, but not all of
+them? Can you specify an arbitrary partial order? The answer is ... yes! The
+details can be found [here](cook_book.md#OrderedCalls).)
+
+### All Expectations Are Sticky (Unless Said Otherwise) {#StickyExpectations}
+
+Now let's do a quick quiz to see how well you can use this mock stuff already.
+How would you test that the turtle is asked to go to the origin *exactly twice*
+(you want to ignore any other instructions it receives)?
+
+After you've come up with your answer, take a look at ours and compare notes
+(solve it yourself first - don't cheat!):
+
+```cpp
+using ::testing::_;
+using ::testing::AnyNumber;
+...
+EXPECT_CALL(turtle, GoTo(_, _)) // #1
+ .Times(AnyNumber());
+EXPECT_CALL(turtle, GoTo(0, 0)) // #2
+ .Times(2);
+```
+
+Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, gMock will
+see that the arguments match expectation #2 (remember that we always pick the
+last matching expectation). Now, since we said that there should be only two
+such calls, gMock will report an error immediately. This is basically what we've
+told you in the [Using Multiple Expectations](#MultiExpectations) section above.
+
+This example shows that **expectations in gMock are "sticky" by default**, in
+the sense that they remain active even after we have reached their invocation
+upper bounds. This is an important rule to remember, as it affects the meaning
+of the spec, and is **different** to how it's done in many other mocking
+frameworks (Why'd we do that? Because we think our rule makes the common cases
+easier to express and understand.).
+
+Simple? Let's see if you've really understood it: what does the following code
+say?
+
+```cpp
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i));
+}
+```
+
+If you think it says that `turtle.GetX()` will be called `n` times and will
+return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we
+said, expectations are sticky. So, the second time `turtle.GetX()` is called,
+the last (latest) `EXPECT_CALL()` statement will match, and will immediately
+lead to an "upper bound violated" error - this piece of code is not very useful!
+
+One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is
+to explicitly say that the expectations are *not* sticky. In other words, they
+should *retire* as soon as they are saturated:
+
+```cpp
+using ::testing::Return;
+...
+for (int i = n; i > 0; i--) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+}
+```
+
+And, there's a better way to do it: in this case, we expect the calls to occur
+in a specific order, and we line up the actions to match the order. Since the
+order is important here, we should make it explicit using a sequence:
+
+```cpp
+using ::testing::InSequence;
+using ::testing::Return;
+...
+{
+ InSequence s;
+
+ for (int i = 1; i <= n; i++) {
+ EXPECT_CALL(turtle, GetX())
+ .WillOnce(Return(10*i))
+ .RetiresOnSaturation();
+ }
+}
+```
+
+By the way, the other situation where an expectation may *not* be sticky is when
+it's in a sequence - as soon as another expectation that comes after it in the
+sequence has been used, it automatically retires (and will never be used to
+match any call).
+
+### Uninteresting Calls
+
+A mock object may have many methods, and not all of them are that interesting.
+For example, in some tests we may not care about how many times `GetX()` and
+`GetY()` get called.
+
+In gMock, if you are not interested in a method, just don't say anything about
+it. If a call to this method occurs, you'll see a warning in the test output,
+but it won't be a failure. This is called "naggy" behavior; to change, see
+[The Nice, the Strict, and the Naggy](cook_book.md#NiceStrictNaggy).

+
+### When I call a method on my mock object, the method for the real object is invoked instead. What's the problem?
+
+In order for a method to be mocked, it must be *virtual*, unless you use the
+[high-perf dependency injection technique](cook_book.md#MockingNonVirtualMethods).
+
+### Can I mock a variadic function?
+
+You cannot mock a variadic function (i.e. a function taking ellipsis (`...`)
+arguments) directly in gMock.
+
+The problem is that in general, there is *no way* for a mock object to know how
+many arguments are passed to the variadic method, and what the arguments' types
+are. Only the *author of the base class* knows the protocol, and we cannot look
+into his or her head.
+
+Therefore, to mock such a function, the *user* must teach the mock object how to
+figure out the number of arguments and their types. One way to do it is to
+provide overloaded versions of the function.
+
+Ellipsis arguments are inherited from C and not really a C++ feature. They are
+unsafe to use and don't work with arguments that have constructors or
+destructors. Therefore we recommend to avoid them in C++ as much as possible.
+
+### MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why?
+
+If you compile this using Microsoft Visual C++ 2005 SP1:
+
+```cpp
+class Foo {
+ ...
+ virtual void Bar(const int i) = 0;
+};
+
+class MockFoo : public Foo {
+ ...
+ MOCK_METHOD(void, Bar, (const int i), (override));
+};
+```
+
+You may get the following warning:
+
+```shell
+warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
+```
+
+This is a MSVC bug. The same code compiles fine with gcc, for example. If you
+use Visual C++ 2008 SP1, you would get the warning:
+
+```shell
+warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
+```
+
+In C++, if you *declare* a function with a `const` parameter, the `const`
+modifier is ignored. Therefore, the `Foo` base class above is equivalent to:
+
+```cpp
+class Foo {
+ ...
+ virtual void Bar(int i) = 0; // int or const int? Makes no difference.
+};
+```
+
+In fact, you can *declare* `Bar()` with an `int` parameter, and define it with a
+`const int` parameter. The compiler will still match them up.
+
+Since making a parameter `const` is meaningless in the method declaration, we
+recommend to remove it in both `Foo` and `MockFoo`. That should workaround the
+VC bug.
+
+Note that we are talking about the *top-level* `const` modifier here. If the
+function parameter is passed by pointer or reference, declaring the pointee or
+referee as `const` is still meaningful. For example, the following two
+declarations are *not* equivalent:
+
+```cpp
+void Bar(int* p); // Neither p nor *p is const.
+void Bar(const int* p); // p is not const, but *p is.
+```

+
+### I can't figure out why gMock thinks my expectations are not satisfied. What should I do?
+
+You might want to run your test with `--gmock_verbose=info`. This flag lets
+gMock print a trace of every mock function call it receives. By studying the
+trace, you'll gain insights on why the expectations you set are not met.
+
+If you see the message "The mock function has no default action set, and its
+return type has no default value set.", then try
+[adding a default action](for_dummies.md#DefaultValue). Due to a known issue,
+unexpected calls on mocks without default actions don't print out a detailed
+comparison between the actual arguments and the expected arguments.
+
+### My program crashed and `ScopedMockLog` spit out tons of messages. Is it a gMock bug?
+
+gMock and `ScopedMockLog` are likely doing the right thing here.
+
+When a test crashes, the failure signal handler will try to log a lot of
+information (the stack trace, and the address map, for example). The messages
+are compounded if you have many threads with depth stacks. When `ScopedMockLog`
+intercepts these messages and finds that they don't match any expectations, it
+prints an error for each of them.
+
+You can learn to ignore the errors, or you can rewrite your expectations to make
+your test more robust, for example, by adding something like:
+
+```cpp
+using ::testing::AnyNumber;
+using ::testing::Not;
+...
+ // Ignores any log not done by us.
+ EXPECT_CALL(log, Log(_, Not(EndsWith("/my_file.cc")), _))
+ .Times(AnyNumber());
+```
+
+### How can I assert that a function is NEVER called?
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .Times(0);
+```
+
+<!-- GOOGLETEST_CM0031 DO NOT DELETE -->
+
+### I have a failed test where gMock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant?
+
+When gMock detects a failure, it prints relevant information (the mock function
+arguments, the state of relevant expectations, and etc) to help the user debug.
+If another failure is detected, gMock will do the same, including printing the
+state of relevant expectations.
+
+Sometimes an expectation's state didn't change between two failures, and you'll
+see the same description of the state twice. They are however *not* redundant,
+as they refer to *different points in time*. The fact they are the same *is*
+interesting information.
+
+### I get a heapcheck failure when using a mock object, but using a real object is fine. What can be wrong?
+
+Does the class (hopefully a pure interface) you are mocking have a virtual
+destructor?
+
+Whenever you derive from a base class, make sure its destructor is virtual.
+Otherwise Bad Things will happen. Consider the following code:
+
+```cpp
+class Base {
+ public:
+ // Not virtual, but should be.
+ ~Base() { ... }
+ ...
+};
+
+class Derived : public Base {
+ public:
+ ...
+ private:
+ std::string value_;
+};
+
+...
+ Base* p = new Derived;
+ ...
+ delete p; // Surprise! ~Base() will be called, but ~Derived() will not
+ // - value_ is leaked.
+```
+
+By changing `~Base()` to virtual, `~Derived()` will be correctly called when
+`delete p` is executed, and the heap checker will be happy.
+
+### The "newer expectations override older ones" rule makes writing expectations awkward. Why does gMock do that?
+
+When people complain about this, often they are referring to code like:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time. However, I have to write the expectations in the
+ // reverse order. This sucks big time!!!
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+```
+
+The problem, is that they didn't pick the **best** way to express the test's
+intent.
+
+By default, expectations don't have to be matched in *any* particular order. If
+you want them to match in a certain order, you need to be explicit. This is
+gMock's (and jMock's) fundamental philosophy: it's easy to accidentally
+over-specify your tests, and we want to make it harder to do so.
+
+There are two better ways to write the test spec. You could either put the
+expectations in sequence:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time. Using a sequence, we can write the expectations
+ // in their natural order.
+ {
+ InSequence s;
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .RetiresOnSaturation();
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+ }
+```
+
+or you can put the sequence of actions in the same expectation:
+
+```cpp
+using ::testing::Return;
+...
+ // foo.Bar() should be called twice, return 1 the first time, and return
+ // 2 the second time.
+ EXPECT_CALL(foo, Bar())
+ .WillOnce(Return(1))
+ .WillOnce(Return(2))
+ .RetiresOnSaturation();
+```
+
+Back to the original questions: why does gMock search the expectations (and
+`ON_CALL`s) from back to front? Because this allows a user to set up a mock's
+behavior for the common case early (e.g. in the mock's constructor or the test
+fixture's set-up phase) and customize it with more specific rules later. If
+gMock searches from front to back, this very useful pattern won't be possible.
+
+### gMock prints a warning when a function without EXPECT_CALL is called, even if I have set its behavior using ON_CALL. Would it be reasonable not to show the warning in this case?
+
+When choosing between being neat and being safe, we lean toward the latter. So
+the answer is that we think it's better to show the warning.
+
+Often people write `ON_CALL`s in the mock object's constructor or `SetUp()`, as
+the default behavior rarely changes from test to test. Then in the test body
+they set the expectations, which are often different for each test. Having an
+`ON_CALL` in the set-up part of a test doesn't mean that the calls are expected.
+If there's no `EXPECT_CALL` and the method is called, it's possibly an error. If
+we quietly let the call go through without notifying the user, bugs may creep in
+unnoticed.
+
+If, however, you are sure that the calls are OK, you can write
+
+```cpp
+using ::testing::_;
+...
+ EXPECT_CALL(foo, Bar(_))
+ .WillRepeatedly(...);
+```
+
+instead of
+
+```cpp
+using ::testing::_;
+...
+ ON_CALL(foo, Bar(_))
+ .WillByDefault(...);
+```
+
+This tells gMock that you do expect the calls and no warning should be printed.
+
+Also, you can control the verbosity by specifying `--gmock_verbose=error`. Other
+values are `info` and `warning`. If you find the output too noisy when
+debugging, just choose a less verbose level.
+
+### How can I delete the mock function's argument in an action?
+
+If your mock function takes a pointer argument and you want to delete that
+argument, you can use testing::DeleteArg<N>() to delete the N'th (zero-indexed)
+argument:
+
+```cpp
+using ::testing::_;
+ ...
+ MOCK_METHOD(void, Bar, (X* x, const Y& y));
+ ...
+ EXPECT_CALL(mock_foo_, Bar(_, _))
+ .WillOnce(testing::DeleteArg<0>()));
+```
+
+### How can I perform an arbitrary action on a mock function's argument?
+
+If you find yourself needing to perform some action that's not supported by
+gMock directly, remember that you can define your own actions using
+[`MakeAction()`](#NewMonoActions) or
+[`MakePolymorphicAction()`](#NewPolyActions), or you can write a stub function
+and invoke it using [`Invoke()`](#FunctionsAsActions).
+
+```cpp
+using ::testing::_;
+using ::testing::Invoke;
+ ...
+ MOCK_METHOD(void, Bar, (X* p));
+ ...
+ EXPECT_CALL(mock_foo_, Bar(_))
+ .WillOnce(Invoke(MyAction(...)));
+```
+
+### My code calls a static/global function. Can I mock it?
+
+You can, but you need to make some changes.
+
+In general, if you find yourself needing to mock a static function, it's a sign
+that your modules are too tightly coupled (and less flexible, less reusable,
+less testable, etc). You are probably better off defining a small interface and
+call the function through that interface, which then can be easily mocked. It's
+a bit of work initially, but usually pays for itself quickly.
+
+This Google Testing Blog
+[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html) says it
+excellently. Check it out.
+
+### My mock object needs to do complex stuff. It's a lot of pain to specify the actions. gMock sucks!
+
+I know it's not a question, but you get an answer for free any way. :-)
+
+With gMock, you can create mocks in C++ easily. And people might be tempted to
+use them everywhere. Sometimes they work great, and sometimes you may find them,
+well, a pain to use. So, what's wrong in the latter case?
+
+When you write a test without using mocks, you exercise the code and assert that
+it returns the correct value or that the system is in an expected state. This is
+sometimes called "state-based testing".
+
+Mocks are great for what some call "interaction-based" testing: instead of
+checking the system state at the very end, mock objects verify that they are
+invoked the right way and report an error as soon as it arises, giving you a
+handle on the precise context in which the error was triggered. This is often
+more effective and economical to do than state-based testing.
+
+If you are doing state-based testing and using a test double just to simulate
+the real object, you are probably better off using a fake. Using a mock in this
+case causes pain, as it's not a strong point for mocks to perform complex
+actions. If you experience this and think that mocks suck, you are just not
+using the right tool for your problem. Or, you might be trying to solve the
+wrong problem. :-)
+
+### I got a warning "Uninteresting function call encountered - default action taken.." Should I panic?
+
+By all means, NO! It's just an FYI. :-)
+
+What it means is that you have a mock function, you haven't set any expectations
+on it (by gMock's rule this means that you are not interested in calls to this
+function and therefore it can be called any number of times), and it is called.
+That's OK - you didn't say it's not OK to call the function!
+
+What if you actually meant to disallow this function to be called, but forgot to
+write `EXPECT_CALL(foo, Bar()).Times(0)`? While one can argue that it's the
+user's fault, gMock tries to be nice and prints you a note.
+
+So, when you see the message and believe that there shouldn't be any
+uninteresting calls, you should investigate what's going on. To make your life
+easier, gMock dumps the stack trace when an uninteresting call is encountered.
+From that you can figure out which mock function it is, and how it is called.
+
+### I want to define a custom action. Should I use Invoke() or implement the ActionInterface interface?
+
+Either way is fine - you want to choose the one that's more convenient for your
+circumstance.
+
+Usually, if your action is for a particular function type, defining it using
+`Invoke()` should be easier; if your action can be used in functions of
+different types (e.g. if you are defining `Return(*value*)`),
+`MakePolymorphicAction()` is easiest. Sometimes you want precise control on what
+types of functions the action can be used in, and implementing `ActionInterface`
+is the way to go here. See the implementation of `Return()` in
+`testing/base/public/gmock-actions.h` for an example.
+
+### I use SetArgPointee() in WillOnce(), but gcc complains about "conflicting return type specified". What does it mean?
+
+You got this error as gMock has no idea what value it should return when the
+mock method is called. `SetArgPointee()` says what the side effect is, but
+doesn't say what the return value should be. You need `DoAll()` to chain a
+`SetArgPointee()` with a `Return()` that provides a value appropriate to the API
+being mocked.
+
+See this [recipe](cook_book.md#mocking-side-effects) for more details and an
+example.
+
+### I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do?
+
+We've noticed that when the `/clr` compiler flag is used, Visual C++ uses 5~6
+times as much memory when compiling a mock class. We suggest to avoid `/clr`
+when compiling native C++ mocks.

+
+# The Problem
+
+Template and macro libraries often need to define many classes, functions, or
+macros that vary only (or almost only) in the number of arguments they take.
+It's a lot of repetitive, mechanical, and error-prone work.
+
+Our experience is that it's tedious to write custom scripts, which tend to
+reflect the structure of the generated code poorly and are often hard to read
+and edit. For example, a small change needed in the generated code may require
+some non-intuitive, non-trivial changes in the script. This is especially
+painful when experimenting with the code.
+
+This script may be useful for generating meta code, for example a series of
+macros of FOO1, FOO2, etc. Nevertheless, please make it your last resort
+technique by favouring C++ template metaprogramming or variadic macros.
+
+# Our Solution
+
+Pump (for Pump is Useful for Meta Programming, Pretty Useful for Meta
+Programming, or Practical Utility for Meta Programming, whichever you prefer) is
+a simple meta-programming tool for C++. The idea is that a programmer writes a
+`foo.pump` file which contains C++ code plus meta code that manipulates the C++
+code. The meta code can handle iterations over a range, nested iterations, local
+meta variable definitions, simple arithmetic, and conditional expressions. You
+can view it as a small Domain-Specific Language. The meta language is designed
+to be non-intrusive (s.t. it won't confuse Emacs' C++ mode, for example) and
+concise, making Pump code intuitive and easy to maintain.
+
+## Highlights
+
+* The implementation is in a single Python script and thus ultra portable: no
+ build or installation is needed and it works cross platforms.
+* Pump tries to be smart with respect to
+ [Google's style guide](https://github.com/google/styleguide): it breaks long
+ lines (easy to have when they are generated) at acceptable places to fit
+ within 80 columns and indent the continuation lines correctly.
+* The format is human-readable and more concise than XML.
+* The format works relatively well with Emacs' C++ mode.
+
+## Examples
+
+The following Pump code (where meta keywords start with `$`, `[[` and `]]` are
+meta brackets, and `$$` starts a meta comment that ends with the line):
+
+```
+$var n = 3 $$ Defines a meta variable n.
+$range i 0..n $$ Declares the range of meta iterator i (inclusive).
+$for i [[
+ $$ Meta loop.
+// Foo$i does blah for $i-ary predicates.
+$range j 1..i
+template <size_t N $for j [[, typename A$j]]>
+class Foo$i {
+$if i == 0 [[
+ blah a;
+]] $elif i <= 2 [[
+ blah b;
+]] $else [[
+ blah c;
+]]
+};
+
+]]
+```
+
+will be translated by the Pump compiler to:
+
+```cpp
+// Foo0 does blah for 0-ary predicates.
+template <size_t N>
+class Foo0 {
+ blah a;
+};
+
+// Foo1 does blah for 1-ary predicates.
+template <size_t N, typename A1>
+class Foo1 {
+ blah b;
+};
+
+// Foo2 does blah for 2-ary predicates.
+template <size_t N, typename A1, typename A2>
+class Foo2 {
+ blah b;
+};
+
+// Foo3 does blah for 3-ary predicates.
+template <size_t N, typename A1, typename A2, typename A3>
+class Foo3 {
+ blah c;
+};
+```
+
+In another example,
+
+```
+$range i 1..n
+Func($for i + [[a$i]]);
+$$ The text between i and [[ is the separator between iterations.
+```
+
+will generate one of the following lines (without the comments), depending on
+the value of `n`:
+
+```cpp
+Func(); // If n is 0.
+Func(a1); // If n is 1.
+Func(a1 + a2); // If n is 2.
+Func(a1 + a2 + a3); // If n is 3.
+// And so on...
+```
+
+## Constructs
+
+We support the following meta programming constructs:
+
+| `$var id = exp` | Defines a named constant value. `$id` is |
+: : valid until the end of the current meta :
+: : lexical block. :
+| :------------------------------- | :--------------------------------------- |
+| `$range id exp..exp` | Sets the range of an iteration variable, |
+: : which can be reused in multiple loops :
+: : later. :
+| `$for id sep [[ code ]]` | Iteration. The range of `id` must have |
+: : been defined earlier. `$id` is valid in :
+: : `code`. :
+| `$($)` | Generates a single `$` character. |
+| `$id` | Value of the named constant or iteration |
+: : variable. :
+| `$(exp)` | Value of the expression. |
+| `$if exp [[ code ]] else_branch` | Conditional. |
+| `[[ code ]]` | Meta lexical block. |
+| `cpp_code` | Raw C++ code. |
+| `$$ comment` | Meta comment. |
+
+**Note:** To give the user some freedom in formatting the Pump source code, Pump
+ignores a new-line character if it's right after `$for foo` or next to `[[` or
+`]]`. Without this rule you'll often be forced to write very long lines to get
+the desired output. Therefore sometimes you may need to insert an extra new-line
+in such places for a new-line to show up in your output.
+
+## Grammar
+
+```ebnf
+code ::= atomic_code*
+atomic_code ::= $var id = exp
+ | $var id = [[ code ]]
+ | $range id exp..exp
+ | $for id sep [[ code ]]
+ | $($)
+ | $id
+ | $(exp)
+ | $if exp [[ code ]] else_branch
+ | [[ code ]]
+ | cpp_code
+sep ::= cpp_code | empty_string
+else_branch ::= $else [[ code ]]
+ | $elif exp [[ code ]] else_branch
+ | empty_string
+exp ::= simple_expression_in_Python_syntax
+```
+
+## Code
+
+You can find the source code of Pump in [scripts/pump.py](../scripts/pump.py).
+It is still very unpolished and lacks automated tests, although it has been
+successfully used many times. If you find a chance to use it in your project,
+please let us know what you think! We also welcome help on improving Pump.
+
+## Real Examples
+
+You can find real-world applications of Pump in
+[Google Test](https://github.com/google/googletest/tree/master/googletest) and
+[Google Mock](https://github.com/google/googletest/tree/master/googlemock). The
+source file `foo.h.pump` generates `foo.h`.
+
+## Tips
+
+* If a meta variable is followed by a letter or digit, you can separate them
+ using `[[]]`, which inserts an empty string. For example `Foo$j[[]]Helper`
+ generate `Foo1Helper` when `j` is 1.
+* To avoid extra-long Pump source lines, you can break a line anywhere you
+ want by inserting `[[]]` followed by a new line. Since any new-line
+ character next to `[[` or `]]` is ignored, the generated code won't contain
+ this new line.

+// Google Mock - a framework for writing C++ mock classes.
+//
+// The ACTION* family of macros can be used in a namespace scope to
+// define custom actions easily. The syntax:
+//
+// ACTION(name) { statements; }
+//
+// will define an action with the given name that executes the
+// statements. The value returned by the statements will be used as
+// the return value of the action. Inside the statements, you can
+// refer to the K-th (0-based) argument of the mock function by
+// 'argK', and refer to its type by 'argK_type'. For example:
+//
+// ACTION(IncrementArg1) {
+// arg1_type temp = arg1;
+// return ++(*temp);
+// }
+//
+// allows you to write
+//
+// ...WillOnce(IncrementArg1());
+//
+// You can also refer to the entire argument tuple and its type by
+// 'args' and 'args_type', and refer to the mock function type and its
+// return type by 'function_type' and 'return_type'.
+//
+// Note that you don't need to specify the types of the mock function
+// arguments. However rest assured that your code is still type-safe:
+// you'll get a compiler error if *arg1 doesn't support the ++
+// operator, or if the type of ++(*arg1) isn't compatible with the
+// mock function's return type, for example.
+//
+// Sometimes you'll want to parameterize the action. For that you can use
+// another macro:
+//
+// ACTION_P(name, param_name) { statements; }
+//
+// For example:
+//
+// ACTION_P(Add, n) { return arg0 + n; }
+//
+// will allow you to write:
+//
+// ...WillOnce(Add(5));
+//
+// Note that you don't need to provide the type of the parameter
+// either. If you need to reference the type of a parameter named
+// 'foo', you can write 'foo_type'. For example, in the body of
+// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
+// of 'n'.
+//
+// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
+// multi-parameter actions.
+//
+// For the purpose of typing, you can view
+//
+// ACTION_Pk(Foo, p1, ..., pk) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// In particular, you can provide the template type arguments
+// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
+// although usually you can rely on the compiler to infer the types
+// for you automatically. You can assign the result of expression
+// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
+// pk_type>. This can be useful when composing actions.
+//
+// You can also overload actions with different numbers of parameters:
+//
+// ACTION_P(Plus, a) { ... }
+// ACTION_P2(Plus, a, b) { ... }
+//
+// While it's tempting to always use the ACTION* macros when defining
+// a new action, you should also consider implementing ActionInterface
+// or using MakePolymorphicAction() instead, especially if you need to
+// use the action a lot. While these approaches require more work,
+// they give you more control on the types of the mock function
+// arguments and the action parameters, which in general leads to
+// better compiler error messages that pay off in the long run. They
+// also allow overloading actions based on parameter types (as opposed
+// to just based on the number of parameters).
+//
+// CAVEAT:
+//
+// ACTION*() can only be used in a namespace scope as templates cannot be
+// declared inside of a local class.
+// Users can, however, define any local functors (e.g. a lambda) that
+// can be used as actions.
+//
+// MORE INFORMATION:
+//

+
+// Sometimes you want to give an action explicit template parameters
+// that cannot be inferred from its value parameters. ACTION() and
+// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
+// and can be viewed as an extension to ACTION() and ACTION_P*().
+//
+// The syntax:
+//
+// ACTION_TEMPLATE(ActionName,
+// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters. name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::std::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.
+
+// Declares the template parameters.

+// Sometimes you want to give an action explicit template parameters
+// that cannot be inferred from its value parameters. ACTION() and
+// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
+// and can be viewed as an extension to ACTION() and ACTION_P*().
+//
+// The syntax:
+//
+// ACTION_TEMPLATE(ActionName,
+// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters. name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::std::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.

+
+// Google Mock - a framework for writing C++ mock classes.
+//
+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.
+//
+// Basic Usage
+// ===========
+//
+// The syntax
+//
+// MATCHER(name, description_string) { statements; }
+//
+// defines a matcher with the given name that executes the statements,
+// which must return a bool to indicate if the match succeeds. Inside
+// the statements, you can refer to the value being matched by 'arg',
+// and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails. Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects. It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+// MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+// // Expects mock_foo.Bar(n) to be called where n is even.
+// EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+// // Verifies that the value of some_expression is even.
+// EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+// Value of: some_expression
+// Expected: is even
+// Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Argument Type
+// =============
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you). This allows the matcher to be
+// polymorphic. For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool. In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Parameterizing Matchers
+// =======================
+//
+// Sometimes you'll want to parameterize the matcher. For that you
+// can use another macro:
+//
+// MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+// Value of: Blah("a")
+// Expected: has absolute value 10
+// Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'. For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
+// support multi-parameter matchers.
+//
+// Describing Parameterized Matchers
+// =================================
+//
+// The last argument to MATCHER*() is a string-typed expression. The
+// expression can reference all of the matcher's parameters and a
+// special bool-typed variable named 'negation'. When 'negation' is
+// false, the expression should evaluate to the matcher's description;
+// otherwise it should evaluate to the description of the negation of
+// the matcher. For example,
+//
+// using testing::PrintToString;
+//
+// MATCHER_P2(InClosedRange, low, hi,
+// std::string(negation ? "is not" : "is") + " in range [" +
+// PrintToString(low) + ", " + PrintToString(hi) + "]") {
+// return low <= arg && arg <= hi;
+// }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: is in range [4, 6]
+// ...
+// Expected: is not in range [2, 4]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple. For example,
+//
+// MATCHER_P2(InClosedRange, low, hi, "") { ... }
+// ...
+// EXPECT_THAT(3, InClosedRange(4, 6));
+// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
+//
+// would generate two failures that contain the text:
+//
+// Expected: in closed range (4, 6)
+// ...
+// Expected: not (in closed range (2, 4))
+//
+// Types of Matcher Parameters
+// ===========================
+//
+// For the purpose of typing, you can view
+//
+// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+// template <typename p1_type, ..., typename pk_type>
+// FooMatcherPk<p1_type, ..., pk_type>
+// Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you. If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false). As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used. You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable. If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// Explaining Match Results
+// ========================
+//
+// Sometimes the matcher description alone isn't enough to explain why
+// the match has failed or succeeded. For example, when expecting a
+// long string, it can be very helpful to also print the diff between
+// the expected string and the actual one. To achieve that, you can
+// optionally stream additional information to a special variable
+// named result_listener, whose type is a pointer to class
+// MatchResultListener:
+//
+// MATCHER_P(EqualsLongString, str, "") {
+// if (arg == str) return true;
+//
+// *result_listener << "the difference: "
+/// << DiffStrings(str, arg);
+// return false;
+// }
+//
+// Overloading Matchers
+// ====================
+//
+// You can overload matchers with different numbers of parameters:
+//
+// MATCHER_P(Blah, a, description_string1) { ... }
+// MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// Caveats
+// =======
+//
+// When defining a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher(). These
+// approaches require more work than the MATCHER* macros, but also
+// give you more control on the types of the value being matched and
+// the matcher parameters, which may leads to better compiler error
+// messages when the matcher is used wrong. They also allow
+// overloading matchers based on parameter types (as opposed to just
+// based on the number of parameters).
+//
+// MATCHER*() can only be used in a namespace scope as templates cannot be
+// declared inside of a local class.
+//
+// More Information
+// ================
+//
+// To learn more about using these macros, please search for 'MATCHER'
+// on
+// https://github.com/google/googletest/blob/master/googlemock/docs/cook_book.md
+//
+// This file also implements some commonly used argument matchers. More
+// matchers can be defined by the user implementing the
+// MatcherInterface<T> interface if necessary.
+//
+// See googletest/include/gtest/gtest-matchers.h for the definition of class
+// Matcher, class MatcherInterface, and others.

+// Implements class templates NiceMock, NaggyMock, and StrictMock.
+//
+// Given a mock class MockFoo that is created using Google Mock,
+// NiceMock<MockFoo> is a subclass of MockFoo that allows
+// uninteresting calls (i.e. calls to mock methods that have no
+// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
+// that prints a warning when an uninteresting call occurs, and
+// StrictMock<MockFoo> is a subclass of MockFoo that treats all
+// uninteresting calls as errors.
+//
+// Currently a mock is naggy by default, so MockFoo and
+// NaggyMock<MockFoo> behave like the same. However, we will soon
+// switch the default behavior of mocks to be nice, as that in general
+// leads to more maintainable tests. When that happens, MockFoo will
+// stop behaving like NaggyMock<MockFoo> and start behaving like
+// NiceMock<MockFoo>.
+//
+// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
+// their respective base class. Therefore you can write
+// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
+// has a constructor that accepts (int, const char*), for example.
+//
+// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
+// and StrictMock<MockFoo> only works for mock methods defined using
+// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
+// If a mock method is defined in a base class of MockFoo, the "nice"
+// or "strict" modifier may not affect it, depending on the compiler.
+// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
+// supported.

+// A MockFunction<F> type has one mock method whose type is
+// internal::SignatureOfT<F>. It is useful when you just want your
+// test code to emit some messages and have Google Mock verify the
+// right messages are sent (and perhaps at the right times). For
+// example, if you are exercising code:
+//
+// Foo(1);
+// Foo(2);
+// Foo(3);
+//
+// and want to verify that Foo(1) and Foo(3) both invoke
+// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
+//
+// TEST(FooTest, InvokesBarCorrectly) {
+// MyMock mock;
+// MockFunction<void(string check_point_name)> check;
+// {
+// InSequence s;
+//
+// EXPECT_CALL(mock, Bar("a"));
+// EXPECT_CALL(check, Call("1"));
+// EXPECT_CALL(check, Call("2"));
+// EXPECT_CALL(mock, Bar("a"));
+// }
+// Foo(1);
+// check.Call("1");
+// Foo(2);
+// check.Call("2");
+// Foo(3);
+// }
+//
+// The expectation spec says that the first Bar("a") must happen
+// before check point "1", the second Bar("a") must happen after check
+// point "2", and nothing should happen between the two check
+// points. The explicit check points make it easy to tell which
+// Bar("a") is called by which call to Foo().
+//
+// MockFunction<F> can also be used to exercise code that accepts
+// std::function<internal::SignatureOfT<F>> callbacks. To do so, use
+// AsStdFunction() method to create std::function proxy forwarding to
+// original object's Call. Example:
+//
+// TEST(FooTest, RunsCallbackWithBarArgument) {
+// MockFunction<int(string)> callback;
+// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
+// Foo(callback.AsStdFunction());
+// }
+//
+// The internal::SignatureOfT<F> indirection allows to use other types
+// than just function signature type. This is typically useful when
+// providing a mock for a predefined std::function type. Example:
+//
+// using FilterPredicate = std::function<bool(string)>;
+// void MyFilterAlgorithm(FilterPredicate predicate);
+//
+// TEST(FooTest, FilterPredicateAlwaysAccepts) {
+// MockFunction<FilterPredicate> predicateMock;
+// EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
+// MyFilterAlgorithm(predicateMock.AsStdFunction());
+// }

+// required to avoid compile errors when the name of the method used in call is
+// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
+// tests in internal/gmock-spec-builders_test.cc for more details.
+//
+// This macro supports statements both with and without parameter matchers. If
+// the parameter list is omitted, gMock will accept any parameters, which allows
+// tests to be written that don't need to encode the number of method
+// parameter. This technique may only be used for non-overloaded methods.
+//
+// // These are the same:
+// ON_CALL(mock, NoArgsMethod()).WillByDefault(...);
+// ON_CALL(mock, NoArgsMethod).WillByDefault(...);
+//
+// // As are these:
+// ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);
+// ON_CALL(mock, TwoArgsMethod).WillByDefault(...);
+//
+// // Can also specify args if you want, of course:
+// ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);
+//
+// // Overloads work as long as you specify parameters:
+// ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);
+// ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);
+//
+// // Oops! Which overload did you want?
+// ON_CALL(mock, OverloadedMethod).WillByDefault(...);
+// => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
+//
+// How this works: The mock class uses two overloads of the gmock_Method
+// expectation setter method plus an operator() overload on the MockSpec object.
+// In the matcher list form, the macro expands to:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod(_, 45))...
+//
+// // ...expands to:
+// mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
+// |-------------v---------------||------------v-------------|
+// invokes first overload swallowed by operator()
+//
+// // ...which is essentially:
+// mock.gmock_TwoArgsMethod(_, 45)...
+//
+// Whereas the form without a matcher list:
+//
+// // This statement:
+// ON_CALL(mock, TwoArgsMethod)...
+//
+// // ...expands to:
+// mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...
+// |-----------------------v--------------------------|
+// invokes second overload
+//
+// // ...which is essentially:
+// mock.gmock_TwoArgsMethod(_, _)...
+//
+// The WithoutMatchers() argument is used to disambiguate overloads and to
+// block the caller from accidentally invoking the second overload directly. The
+// second argument is an internal type derived from the method signature. The
+// failure to disambiguate two overloads of this method in the ON_CALL statement
+// is how we block callers from setting expectations on overloaded methods.

+"""fuse_gmock_files.py v0.1.0.
+
+Fuses Google Mock and Google Test source code into two .h files and a .cc file.
+
+SYNOPSIS
+ fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
+
+ Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
+ code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
+ directory, and generates three files:
+ OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
+ OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
+ by adding OUTPUT_DIR to the include search path and linking
+ with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
+ everything you need to use Google Mock. Hence you can
+ "install" Google Mock by copying them to wherever you want.
+
+ GMOCK_ROOT_DIR can be omitted and defaults to the parent
+ directory of the directory holding this script.
+
+EXAMPLES
+ ./fuse_gmock_files.py fused_gmock
+ ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
+
+This tool is experimental. In particular, it assumes that there is no
+conditional inclusion of Google Mock or Google Test headers. Please
+report any problems to googlemock@googlegroups.com. You can read
+https://github.com/google/googletest/blob/master/googlemock/docs/cook_book.md
+for more
+information.

+
+The Google Mock class generator is an application that is part of cppclean.
+For more information about cppclean, visit http://code.google.com/p/cppclean/
+
+The mock generator requires Python 2.3.5 or later. If you don't have Python
+installed on your system, you will also need to install it. You can download
+Python from: http://www.python.org/download/releases/
+
+To use the Google Mock class generator, you need to call it
+on the command line passing the header file and class for which you want
+to generate a Google Mock class.
+
+Make sure to install the scripts somewhere in your path. Then you can
+run the program.
+
+ gmock_gen.py header-file.h [ClassName]...
+
+If no ClassNames are specified, all classes in the file are emitted.
+
+To change the indentation from the default of 2, set INDENT in
+the environment. For example to use an indent of 4 spaces:
+
+INDENT=4 gmock_gen.py header-file.h ClassName
+
+This version was made from SVN revision 281 in the cppclean repository.
+
+Known Limitations
+-----------------
+Not all code will be generated properly. For example, when mocking templated
+classes, the template information is lost. You will need to add the template
+information manually.
+
+Not all permutations of using multiple pointers/references will be rendered
+properly. These will also have to be fixed manually.

+Goal:
+-----
+ CppClean attempts to find problems in C++ source that slow development
+ in large code bases, for example various forms of unused code.
+ Unused code can be unused functions, methods, data members, types, etc
+ to unnecessary #include directives. Unnecessary #includes can cause
+ considerable extra compiles increasing the edit-compile-run cycle.
+
+ The project home page is: http://code.google.com/p/cppclean/
+
+
+Features:
+---------
+ * Find and print C++ language constructs: classes, methods, functions, etc.
+ * Find classes with virtual methods, no virtual destructor, and no bases
+ * Find global/static data that are potential problems when using threads
+ * Unnecessary forward class declarations
+ * Unnecessary function declarations
+ * Undeclared function definitions
+ * (planned) Find unnecessary header files #included
+ - No direct reference to anything in the header
+ - Header is unnecessary if classes were forward declared instead
+ * (planned) Source files that reference headers not directly #included,
+ ie, files that rely on a transitive #include from another header
+ * (planned) Unused members (private, protected, & public) methods and data
+ * (planned) Store AST in a SQL database so relationships can be queried
+
+AST is Abstract Syntax Tree, a representation of parsed source code.
+http://en.wikipedia.org/wiki/Abstract_syntax_tree
+
+
+System Requirements:
+--------------------
+ * Python 2.4 or later (2.3 probably works too)
+ * Works on Windows (untested), Mac OS X, and Unix
+
+
+How to Run:
+-----------
+ For all examples, it is assumed that cppclean resides in a directory called
+ /cppclean.
+
+ To print warnings for classes with virtual methods, no virtual destructor and
+ no base classes:
+
+ /cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ...
+
+ To print all the functions defined in header file(s):
+
+ /cppclean/run.sh functions.py file1.h file2.h ...
+
+ All the commands take multiple files on the command line. Other programs
+ include: find_warnings, headers, methods, and types. Some other programs
+ are available, but used primarily for debugging.
+
+ run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then
+ runs the program in /cppclean/cpp/PROGRAM.py. There is currently
+ no equivalent for Windows. Contributions for a run.bat file
+ would be greatly appreciated.
+
+
+How to Configure:
+-----------------
+ You can add a siteheaders.py file in /cppclean/cpp to configure where
+ to look for other headers (typically -I options passed to a compiler).
+ Currently two values are supported: _TRANSITIVE and GetIncludeDirs.
+ _TRANSITIVE should be set to a boolean value (True or False) indicating
+ whether to transitively process all header files. The default is False.
+
+ GetIncludeDirs is a function that takes a single argument and returns
+ a sequence of directories to include. This can be a generator or
+ return a static list.
+
+ def GetIncludeDirs(filename):
+ return ['/some/path/with/other/headers']
+
+ # Here is a more complicated example.
+ def GetIncludeDirs(filename):
+ yield '/path1'
+ yield os.path.join('/path2', os.path.dirname(filename))
+ yield '/path3'
+
+
+How to Test:
+------------
+ For all examples, it is assumed that cppclean resides in a directory called
+ /cppclean. The tests require
+
+ cd /cppclean
+ make test
+ # To generate expected results after a change:
+ make expected
+
+
+Current Status:
+---------------
+ The parser works pretty well for header files, parsing about 99% of Google's
+ header files. Anything which inspects structure of C++ source files should
+ work reasonably well. Function bodies are not transformed to an AST,
+ but left as tokens. Much work is still needed on finding unused header files
+ and storing an AST in a database.
+
+
+Non-goals:
+----------
+ * Parsing all valid C++ source
+ * Handling invalid C++ source gracefully
+ * Compiling to machine code (or anything beyond an AST)
+

+// FindMaxBipartiteMatching and its helper class.
+//
+// Uses the well-known Ford-Fulkerson max flow method to find a maximum
+// bipartite matching. Flow is considered to be from left to right.
+// There is an implicit source node that is connected to all of the left
+// nodes, and an implicit sink node that is connected to all of the
+// right nodes. All edges have unit capacity.
+//
+// Neither the flow graph nor the residual flow graph are represented
+// explicitly. Instead, they are implied by the information in 'graph' and
+// a vector<int> called 'left_' whose elements are initialized to the
+// value kUnused. This represents the initial state of the algorithm,
+// where the flow graph is empty, and the residual flow graph has the
+// following edges:
+// - An edge from source to each left_ node
+// - An edge from each right_ node to sink
+// - An edge from each left_ node to each right_ node, if the
+// corresponding edge exists in 'graph'.
+//
+// When the TryAugment() method adds a flow, it sets left_[l] = r for some
+// nodes l and r. This induces the following changes:
+// - The edges (source, l), (l, r), and (r, sink) are added to the
+// flow graph.
+// - The same three edges are removed from the residual flow graph.
+// - The reverse edges (l, source), (r, l), and (sink, r) are added
+// to the residual flow graph, which is a directional graph
+// representing unused flow capacity.
+//
+// When the method augments a flow (moving left_[l] from some r1 to some
+// other r2), this can be thought of as "undoing" the above steps with
+// respect to r1 and "redoing" them with respect to r2.
+//
+// It bears repeating that the flow graph and residual flow graph are
+// never represented explicitly, but can be derived by looking at the
+// information in 'graph' and in left_.
+//
+// As an optimization, there is a second vector<int> called right_ which
+// does not provide any new information. Instead, it enables more
+// efficient queries about edges entering or leaving the right-side nodes
+// of the flow or residual flow graphs. The following invariants are
+// maintained:

+// them in this header and #including it in gmock_link_test.cc and
+// gmock_link2_test.cc. Because the symbols generated by the compiler for
+// those constructs must be identical in both translation units,
+// definitions of Interface and Mock tests MUST be kept in the SAME
+// NON-ANONYMOUS namespace in this file. The test fixture class LinkTest
+// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
+// gmock_link2_test.cc to avoid producing linker errors.
