| 37 // Implements class templates NiceMock and StrictMock. |
| 38 // |
| 39 // Given a mock class MockFoo that is created using Google Mock, |
| 40 // NiceMock<MockFoo> is a subclass of MockFoo that allows |
| 41 // uninteresting calls (i.e. calls to mock methods that have no |
| 42 // EXPECT_CALL specs), and StrictMock<MockFoo> is a subclass of |
| 43 // MockFoo that treats all uninteresting calls as errors. |
| 44 // |
| 45 // NiceMock and StrictMock "inherits" the constructors of their |
| 46 // respective base class, with up-to $n arguments. Therefore you can |
| 47 // write NiceMock<MockFoo>(5, "a") to construct a nice mock where |
| 48 // MockFoo has a constructor that accepts (int, const char*), for |
| 49 // example. |
| 50 // |
| 51 // A known limitation is that NiceMock<MockFoo> and |
| 52 // StrictMock<MockFoo> only works for mock methods defined using the |
| 53 // MOCK_METHOD* family of macros DIRECTLY in the MockFoo class. If a |
| 54 // mock method is defined in a base class of MockFoo, the "nice" or |
| 55 // "strict" modifier may not affect it, depending on the compiler. In |
| 56 // particular, nesting NiceMock and StrictMock is NOT supported. |
| 57 // |
| 58 // Another known limitation is that the constructors of the base mock |
| 59 // cannot have arguments passed by non-const reference, which are |
| 60 // banned by the Google C++ style guide anyway. |
