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).

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. `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`.

Required if overriding a + `noexcept` method. +* **`Calltype(...)`** - Sets the call type for the method (e.g. to + `STDMETHODCALLTYPE`), useful in Windows. + +#### 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, 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: + +<a name="table99"></a> +<table border="1" cellspacing="0" cellpadding="1"> +<tr> <th colspan=2> Simple </th></tr> +<tr> <td> Old </td> <td> `MOCK_METHOD1(Foo, bool(int))` </td> </tr> +<tr> <td> New </td> <td> `MOCK_METHOD(bool, Foo, (int))` </td> </tr> + +<tr> <th colspan=2> Const Method </th></tr> <tr> <td> Old </td> <td> +`MOCK_CONST_METHOD1(Foo, bool(int))` </td> </tr> <tr> <td> New </td> <td> +`MOCK_METHOD(bool, Foo, (int), (const))` </td> </tr> + +<tr> <th colspan=2> Method in a Class Template </th></tr> <tr> <td> Old </td> +<td> `MOCK_METHOD1_T(Foo, bool(int))` </td> </tr> <tr> <td> New </td> <td> +`MOCK_METHOD(bool, Foo, (int))` </td> </tr> + +<tr> <th colspan=2> Const Method in a Class Template </th></tr> <tr> <td> Old +</td> <td> `MOCK_CONST_METHOD1_T(Foo, bool(int))` </td> </tr> <tr> <td> New +</td> <td> `MOCK_METHOD(bool, Foo, (int), (const))` </td> </tr> + +<tr> <th colspan=2> Method with Call Type </th></tr> <tr> <td> Old </td> <td> +`MOCK_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int))` </td> </tr> <tr> +<td> New </td> <td> `MOCK_METHOD(bool, Foo, (int), +(Calltype(STDMETHODCALLTYPE)))` </td> </tr> + +<tr> <th colspan=2> Const Method with Call Type </th></tr> <tr> <td> Old</td> +<td> `MOCK_CONST_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int))` </td> +</tr> <tr> <td> New </td> <td> `MOCK_METHOD(bool, Foo, (int), (const, +Calltype(STDMETHODCALLTYPE)))` </td> </tr> + +<tr> <th colspan=2> Method with Call Type in a Class Template </th></tr> <tr> +<td> Old </td> <td> `MOCK_METHOD1_T_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, +bool(int))` </td> </tr> <tr> <td> New </td> <td> `MOCK_METHOD(bool, Foo, (int), +(Calltype(STDMETHODCALLTYPE)))` </td> </tr> + +<tr> <th colspan=2> Const Method with Call Type in a Class Template </th></tr> +<tr> <td> Old </td> <td> `MOCK_CONST_METHOD1_T_WITH_CALLTYPE(STDMETHODCALLTYPE, +Foo, bool(int))` </td> </tr> <tr> <td> New </td> <td> `MOCK_METHOD(bool, Foo, +(int), (const, Calltype(STDMETHODCALLTYPE)))` </td> </tr> + +</table> + +#### 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 (I dislike them just as much as the next guy, but +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. http://b/28934720 tracks the issue. +3. During the constructor or destructor of `MockFoo`, the mock object is *not* + nice or strict. This may cause surprises if the constructor or destructor + calls a mock method on `this` object. (This behavior, however, is consistent + with C++'s general rule: if a constructor or destructor calls a virtual + method of `this` object, that method is treated as non-virtual. In other + words, to the base class's constructor or destructor, `this` object behaves + like an instance of the base class, not the derived class. This rule is + required for safety. Otherwise a base constructor may use members of a + derived class before they are initialized, or a base destructor may use + members of a derived class after they have been destroyed.) + +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(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). + +The trick is to leave a back door in your mock class for accessing the real +methods in the base class: + +```cpp +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)); + + // Use this to call Concrete() defined in Foo. + int FooConcrete(const char* str) { return Foo::Concrete(str); } +}; +``` + +Now, you can call `Foo::Concrete()` inside an action by: + +```cpp +... + EXPECT_CALL(foo, Concrete).WillOnce([&foo](const char* str) { + return foo.FooConcrete(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.FooConcrete(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)); +``` + +#### 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](#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) ...`. + +<!-- GOOGLETEST_CM0023 DO NOT DELETE --> + +#### 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::ByRef; +using ::testing::Eq; +using ::testing::Lt; +... + // Expects that Foo()'s argument == bar. + EXPECT_CALL(mock_obj, Foo(Eq(ByRef(bar)))); + + // Expects that Foo()'s argument < bar. + EXPECT_CALL(mock_obj, Foo(Lt(ByRef(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 `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 earlier 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 third `EXPECT_CALL()`, but not those +in the first two, then the third 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](#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 `ByRef()`: + +```cpp +using testing::ByRef; +using testing::Return; + +class MockFoo : public Foo { + public: + MOCK_METHOD(int, GetValue, (), (override)); +}; +... + int x = 0; + MockFoo foo; + EXPECT_CALL(foo, GetValue()) + .WillRepeatedly(Return(ByRef(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, `ByRef(x)` +is converted to an `int` value (instead of a `const int&`) when the expectation +is set, and `Return(ByRef(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 you 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)); + .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 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()` is very useful for doing actions that are more complex. It 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. `Invoke()` allows her to 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. + +`InvokeWithoutArgs()` solves this problem. It's like `Invoke()` except that it +doesn't pass the mock function's arguments to the callee. Here's an example: + +```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(InvokeWithoutArgs(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 `ByRef()`: + +```cpp + ... + MOCK_METHOD(bool, Bar, + ((ResultCallback2<bool, int, const Helper&>* callback)), + (override)); + ... + using ::testing::_; + using ::testing::ByRef; + using ::testing::InvokeArgument; + ... + MockFoo foo; + Helper helper; + ... + EXPECT_CALL(foo, Bar(_)) + .WillOnce(InvokeArgument<0>(5, ByRef(helper))); + // ByRef(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 `ByRef()`? 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; + 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, ()); + virtual ~MockFoo() { 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: ... + +foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))... + Function call: F(@0x7fff7c8dada0"a",@0x7fff7c8dad70"b") +Stack trace: ... + +foo_test.cc:16: Failure +Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))... + 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. + +<!-- GOOGLETEST_CM0025 DO NOT DELETE --> + +#### 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 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 call_count calls will satisfy this cardinality. + virtual bool IsSatisfiedByCallCount(int call_count) const = 0; + + // Returns true 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. + +### Useful Mocks Created Using gMock + +<!--#include file="includes/g3_testing_LOGs.md"--> +<!--#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. :-) + +<!-- GOOGLETEST_CM0034 DO NOT DELETE --> diff --git a/src/spawn/test/dependency/googletest/googlemock/docs/for_dummies.md b/src/spawn/test/dependency/googletest/googlemock/docs/for_dummies.md new file mode 100644 index 000000000..e11c18d9b --- /dev/null +++ b/src/spawn/test/dependency/googletest/googlemock/docs/for_dummies.md @@ -0,0 +1,700 @@ +## gMock for Dummies {#GMockForDummies} + +<!-- GOOGLETEST_CM0013 DO NOT DELETE --> + +### 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](#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). diff --git a/src/spawn/test/dependency/googletest/googlemock/docs/gmock_faq.md b/src/spawn/test/dependency/googletest/googlemock/docs/gmock_faq.md new file mode 100644 index 000000000..214aabf12 --- /dev/null +++ b/src/spawn/test/dependency/googletest/googlemock/docs/gmock_faq.md @@ -0,0 +1,396 @@ +## Legacy gMock FAQ {#GMockFaq} + +<!-- GOOGLETEST_CM0021 DO NOT DELETE --> + +### 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](#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. +``` + +<!-- GOOGLETEST_CM0030 DO NOT DELETE --> + +### 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. diff --git a/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-actions.h b/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-actions.h new file mode 100644 index 000000000..9605c43a7 --- /dev/null +++ b/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-actions.h @@ -0,0 +1,1141 @@ +// Copyright 2007, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.

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.

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_P$n to support +// multi-parameter actions. +// +// For the purpose of typing, you can view +// +// ACTION_Pk(Foo, p1, ..., pk) { ... } +// +// as shorthand for +// +// template <typename p1_type, ..., typename pk_type> +// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... } +// +// In particular, you can provide the template type arguments +// explicitly when invoking Foo(), as in Foo<long, bool>(5, false); +// although usually you can rely on the compiler to infer the types +// for you automatically. You can assign the result of expression +// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ..., +// pk_type>. This can be useful when composing actions. +// +// You can also overload actions with different numbers of parameters: +// +// ACTION_P(Plus, a) { ... } +// ACTION_P2(Plus, a, b) { ... } +// +// While it's tempting to always use the ACTION* macros when defining +// a new action, you should also consider implementing ActionInterface +// or using MakePolymorphicAction() instead, especially if you need to +// use the action a lot. While these approaches require more work, +// they give you more control on the types of the mock function +// arguments and the action parameters, which in general leads to +// better compiler error messages that pay off in the long run. They +// also allow overloading actions based on parameter types (as opposed +// to just based on the number of parameters). +// +// CAVEAT: +// +// ACTION*() can only be used in a namespace scope as templates cannot be +// declared inside of a local class. +// Users can, however, define any local functors (e.g. a lambda) that +// can be used as actions. +// +// MORE INFORMATION: +// +// To learn more about using these macros, please search for 'ACTION' on +// https://github.com/google/googletest/blob/master/googlemock/docs/cook_book.md + +$range i 0..n +$range k 0..n-1 + +// An internal macro needed for implementing ACTION*(). +#define GMOCK_ACTION_ARG_TYPES_AND_NAMES_UNUSED_\ + const args_type& args GTEST_ATTRIBUTE_UNUSED_ +$for k [[, \ + const arg$k[[]]_type& arg$k GTEST_ATTRIBUTE_UNUSED_]] + + +// Sometimes you want to give an action explicit template parameters +// that cannot be inferred from its value parameters.

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_P10 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 +//

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 + +$range i 0..n +$for i + +[[ +$var macro_name = [[$if i==0 [[MATCHER]] $elif i==1 [[MATCHER_P]] + $else [[MATCHER_P$i]]]] +$var class_name = [[name##Matcher[[$if i==0 [[]] $elif i==1 [[P]] + $else [[P$i]]]]]] +$range j 0..i-1 +$var template = [[$if i==0 [[]] $else [[ + + template <$for j, [[typename p$j##_type]]>\ +]]]] +$var ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::std::move(gmock_p$j))]]]]]] +$var inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::std::move(gmock_p$j))]]]]]] +$var params = [[$for j, [[p$j]]]] +$var param_types = [[$if i==0 [[]] $else [[<$for j, [[p$j##_type]]>]]]] +$var param_types_and_names = [[$for j, [[p$j##_type p$j]]]] +$var param_field_decls = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] +$var param_field_decls2 = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] + +#define $macro_name(name$for j [[, p$j]], description)\$template + class $class_name {\ + public:\ + template <typename arg_type>\ + class gmock_Impl : public ::testing::MatcherInterface<\ + GTEST_REFERENCE_TO_CONST_(arg_type)> {\ + public:\ + [[$if i==1 [[explicit ]]]]gmock_Impl($impl_ctor_param_list)\ + $impl_inits {}\ + virtual bool MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener) const;\ + virtual void DescribeTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(false);\ + }\ + virtual void DescribeNegationTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(true);\ + }\$param_field_decls + private:\ + ::std::string FormatDescription(bool negation) const {\ + ::std::string gmock_description = (description);\ + if (!gmock_description.empty()) {\ + return gmock_description;\ + }\ + return ::testing::internal::FormatMatcherDescription(\ + negation, #name, \ + ::testing::internal::UniversalTersePrintTupleFieldsToStrings(\ + ::std::tuple<$for j, [[p$j##_type]]>($for j, [[p$j]])));\ + }\ + };\ + template <typename arg_type>\ + operator ::testing::Matcher<arg_type>() const {\ + return ::testing::Matcher<arg_type>(\ + new gmock_Impl<arg_type>($params));\ + }\ + [[$if i==1 [[explicit ]]]]$class_name($ctor_param_list)$inits {\ + }\$param_field_decls2 + private:\ + };\$template + inline $class_name$param_types name($param_types_and_names) {\ + return $class_name$param_types($params);\ + }\$template + template <typename arg_type>\ + bool $class_name$param_types::gmock_Impl<arg_type>::MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener GTEST_ATTRIBUTE_UNUSED_)\ + const +]] + + +#endif // GMOCK_INCLUDE_GMOCK_GMOCK_GENERATED_MATCHERS_H_ diff --git a/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-matchers.h b/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-matchers.h new file mode 100644 index 000000000..fa50903b2 --- /dev/null +++ b/src/spawn/test/dependency/googletest/googlemock/include/gmock/gmock-matchers.h @@ -0,0 +1,4567 @@ +// Copyright 2007, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.
