+// b. Actions and matchers can be instantiated with identical template

+// The following constructs are currently tested:
+// Actions:
+// Return()
+// Return(value)
+// ReturnNull
+// ReturnRef
+// Assign
+// SetArgPointee
+// SetArrayArgument
+// SetErrnoAndReturn
+// Invoke(function)
+// Invoke(object, method)
+// InvokeWithoutArgs(function)
+// InvokeWithoutArgs(object, method)
+// InvokeArgument
+// WithArg
+// WithArgs
+// WithoutArgs
+// DoAll
+// DoDefault
+// IgnoreResult
+// Throw
+// ACTION()-generated
+// ACTION_P()-generated
+// ACTION_P2()-generated
+// Matchers:
+// _
+// A
+// An
+// Eq
+// Gt, Lt, Ge, Le, Ne
+// NotNull
+// Ref
+// TypedEq
+// DoubleEq
+// FloatEq
+// NanSensitiveDoubleEq

+// ResultOf(callback)
+// Pointee
+// Truly(predicate)
+// AddressSatisfies
+// AllOf
+// AnyOf
+// Not
+// MatcherCast<T>
+//
+// Please note: this test does not verify the functioning of these
+// constructs, only that the programs using them will link successfully.
+//
+// Implementation note:
+// This test requires identical definitions of Interface and Mock to be
+// included in different translation units. We achieve this by writing
+// them in this header and #including it in gmock_link_test.cc and
+// gmock_link2_test.cc. Because the symbols generated by the compiler for
+// those constructs must be identical in both translation units,
+// definitions of Interface and Mock tests MUST be kept in the SAME
+// NON-ANONYMOUS namespace in this file. The test fixture class LinkTest
+// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
+// gmock_link2_test.cc to avoid producing linker errors.

+FILE:#: ERROR: this mock object should be deleted but never is. Its address is @0x#.
+ERROR: 3 leaked mock objects found at program exit. Expectations on a mock object are verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.
