  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

  97 //      AnyOf
  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.
