在运行以下代码示例的gtest时，我遇到了问题。ignore header包含了它的可编译性和运行正常。

Error:
GMOCK WARNING:
Uninteresting mock function call - returning default value.
    Function call: receive(0x7ffcee4fc990, 0x7ffcee4fc900)
          Returns: 0
NOTE: You can safely ignore the above warning unless this call should not happen.  Do not suppress it by blindly adding an EXPECT_CALL() if you don't mean to enforce the call.  See https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md#knowing-when-to-expect for details.
/data/home/sipadhy/unit_test_research/gTest/ImplClassTest.cpp:174: Failure
Actual function call count doesn't match EXPECT_CALL(mockImplClass, receive(_, _))...
         Expected: to be called at least once
           Actual: never called - unsatisfied and active

示例代码：

//要模拟的where函数的主类

class ImplClass
public:
    virtual int receive(structX* x, structY* y){ // some logic }
};

//调用主类的中间类

class IntermidiateClass
    std::shared_ptr<ImplClass> implClassPtr = nullptr;
public:
    setImplClassptr(std::shared_ptr<ImplClass> ptr)
        implClassPtr  = ptr;
    int getValue()
        structX x;
        structY y;
        return(implClassPtr->receive(x, y));
};

//模拟类

class MockImplClass: public ImplClass
public:
    MOCK_METHOD2(receive, int(structX, structY));
}

//测试用例

TEST(MyTest, TEST1)
    MockImplClass mockImplClass;
    IntermidiateClass intermidiateObj;
    intermidiateObj.setImplClassptr(std::make_shared<MockImplClass>());
