31 // Google Mock - a framework for writing C++ mock classes.
32 //
33 // This file tests that:
34 // a. A header file defining a mock class can be included in multiple
35 //    translation units without causing a link error.
36 // b. Actions and matchers can be instantiated with identical template
37 //    arguments in different translation units without causing link
38 //    errors.
39 //    The following constructs are currently tested:
40 //    Actions:
41 //      Return()
42 //      Return(value)
43 //      ReturnNull
44 //      ReturnRef
45 //      Assign
46 //      SetArgPointee
47 //      SetArrayArgument
48 //      SetErrnoAndReturn
49 //      Invoke(function)
50 //      Invoke(object, method)
51 //      InvokeWithoutArgs(function)
52 //      InvokeWithoutArgs(object, method)
53 //      InvokeArgument
54 //      WithArg
55 //      WithArgs
56 //      WithoutArgs
57 //      DoAll
58 //      DoDefault
59 //      IgnoreResult
60 //      Throw
61 //      ACTION()-generated
62 //      ACTION_P()-generated
63 //      ACTION_P2()-generated
64 //    Matchers:

98 //      Not
99 //      MatcherCast<T>
100 //
101 //  Please note: this test does not verify the functioning of these
102 //  constructs, only that the programs using them will link successfully.
103 //
104 // Implementation note:
105 // This test requires identical definitions of Interface and Mock to be
106 // included in different translation units.  We achieve this by writing
107 // them in this header and #including it in gmock_link_test.cc and
108 // gmock_link2_test.cc.  Because the symbols generated by the compiler for
109 // those constructs must be identical in both translation units,
110 // definitions of Interface and Mock tests MUST be kept in the SAME
111 // NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
112 // is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
113 // gmock_link2_test.cc to avoid producing linker errors.
