  32 // Google Mock - a framework for writing C++ mock classes.
  33 //
  34 // This file tests that:
  35 // a. A header file defining a mock class can be included in multiple
  36 //    translation units without causing a link error.
  37 // b. Actions and matchers can be instantiated with identical template
  38 //    arguments in different translation units without causing link
  39 //    errors.
  40 //    The following constructs are currently tested:
  41 //    Actions:
  42 //      Return()
  43 //      Return(value)
  44 //      ReturnNull
  45 //      ReturnRef
  46 //      Assign
  47 //      SetArgPointee
  48 //      SetArrayArgument
  49 //      SetErrnoAndReturn
  50 //      Invoke(function)
  51 //      Invoke(object, method)
  52 //      InvokeWithoutArgs(function)
  53 //      InvokeWithoutArgs(object, method)
  54 //      InvokeArgument
  55 //      WithArg
  56 //      WithArgs
  57 //      WithoutArgs
  58 //      DoAll
  59 //      DoDefault
  60 //      IgnoreResult
  61 //      Throw
  62 //      ACTION()-generated
  63 //      ACTION_P()-generated
  64 //      ACTION_P2()-generated
  65 //    Matchers:
  66 //      _
  67 //      A
  68 //      An
  69 //      Eq
  70 //      Gt, Lt, Ge, Le, Ne
  71 //      NotNull
  72 //      Ref
  73 //      TypedEq
  74 //      DoubleEq
  75 //      FloatEq
  76 //      NanSensitiveDoubleEq
  77 //      NanSensitiveFloatEq
  78 //      ContainsRegex
  79 //      MatchesRegex
  80 //      EndsWith
  81 //      HasSubstr
  82 //      StartsWith
  83 //      StrCaseEq
  84 //      StrCaseNe
  85 //      StrEq
  86 //      StrNe
  87 //      ElementsAre
  88 //      ElementsAreArray
  89 //      ContainerEq
  90 //      Field
  91 //      Property
  92 //      ResultOf(function)
  93 //      Pointee
  94 //      Truly(predicate)
  95 //      AllOf
  96 //      AnyOf
  97 //      Not
  98 //      MatcherCast<T>
  99 //
 100 //  Please note: this test does not verify the functioning of these
 101 //  constructs, only that the programs using them will link successfully.
 102 //
 103 // Implementation note:
 104 // This test requires identical definitions of Interface and Mock to be
 105 // included in different translation units.  We achieve this by writing
 106 // them in this header and #including it in gmock_link_test.cc and
 107 // gmock_link2_test.cc.  Because the symbols generated by the compiler for
 108 // those constructs must be identical in both translation units,
 109 // definitions of Interface and Mock tests MUST be kept in the SAME
 110 // NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
 111 // is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
 112 // gmock_link2_test.cc to avoid producing linker errors.
