GMock對Mock對象設置期望後，並把改對象傳給被測代碼。

EXPECT_CALL(mock_object, method(matcher1, matcher2, ...))     .With(multi_argument_matcher)       .Times(cardinality)                 .InSequence(sequences)             .After(expectations)               .WillOnce(action)                 .WillRepeatedly(action)             .RetiresOnSaturation();
