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.
