运行此测试时出现问题或至少出现意外行为: 如果我评论出具体的class MockDefault : public Verifyingcalls::DefaultSCI_OCB { public: MOCK_METHOD0(op, void()); MOCK_METHOD1(op1, void(sc_integer param1)); MOCK_METHOD2(op2, void(sc_boolean param1, sc_integer param2)); }; TEST_F(VerifyCallCount, after3Cycle) { MockDefault defaultMock; EXPECT_CALL(defaultMock, op1(_)).Times(AtLeast(4)); EXPECT_CALL(defaultMock, op2(_,_)).Times(AtLeast(4)); EXPECT_CALL(defaultMock, op1(5l)).Times(AtLeast(2)); EXPECT_CALL(defaultMock, op1(7l)).Times(AtLeast(2)); EXPECT_CALL(defaultMock, op2(true, 7l)).Times(AtLeast(2)); EXPECT_CALL(defaultMock, op2(true, 5l)).Times(AtLeast(2)); ... } 测试工作正常,但如果我没有得到此失败:

错误:

EXPECT_CALL's

问题:

我的问题是,为什么测试失败? 我假设函数Actual function call count doesn't match EXPECT_CALL(defaultMock, op2(_,_))... Expected: to be called at least 4 times Actual: never called - unsatisfied and active ..\gtests\VerifyCallCount\VerifyCallCount.cc:123: Failure 被调用至少4次,至少两次使用参数5和两次使用参数7.那么为什么测试失败?

1 个答案:

答案 0 :(得分:1)

我认为在这种情况下是期望

EXPECT_CALL(defaultMock, op2(true, 7l)).Times(AtLeast(2));
EXPECT_CALL(defaultMock, op2(true, 5l)).Times(AtLeast(2));

被调用并且

EXPECT_CALL(defaultMock, op2(_,_)).Times(AtLeast(4));

未被调用,因为其他两个匹配。使用gmock时,只执行一次匹配,而不是所有匹配。例如EXPECT_CALL可以返回值。如果调用多个匹配,那将不是唯一的。
