GMock EXPECT\u调用不匹配任何匹配器

代码:

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));
...
}

我在运行此测试时遇到问题或至少出现意外行为: EXPECT_CALL's 测试很好,但如果我不这样做,我就会失败:

错误:

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

我的问题是,为什么测试失败? 我假设函数 op1 被调用了至少4次,参数5被调用了至少两次,参数7被调用了两次。那么为什么测试失败了呢?
