Question

I am using gmock in my project and I meet a problem to set a custom reference variable for a mock function. Suppose I have a class as following:

class XXXClient {
public:
    void QueryXXX(const Request&, Response&);
}; 

class XXXRunner {
public:
    void DoSomething(XXXClient&);
};

客户等级为XXXRunner: DoSomething using XXXClient:QueryXXX, and I Want to mock XXXClient to test XXXRunner:DoSomething.

问题是,KeryXXX的第二个参数,即答复,不是回报价值,而是参考变量,我把一些数据填入第三十次的答复:QueryXXX。我想为答复建立一个习俗数据,以核实30Runner的不同状况:DoSomething。

振克框架可以确定预期的回归价值,但我无法找到一种办法确定“回归变量”?

So How to do so?

Answer 1

首先,打上<代码>XXXClient mock category>,请将其名称改为XXXClientMock:

class XXXClientMock : public XXXClient
{
public:
    MOCK_METHOD2(QueryXXX, QueryResult (Request&, Response&));
};

然后,使用GMock 行动SetArgReferee确定习惯参数如下:

TEST(XXXRunnerTC, SetArgRefereeDemo)
{
    XXXCLientMock oMock;

    // set the custom response object
    Response oRsp;
    oRsp.attr1 = “…”;
    oRsp.attr2 = “any thing you like”;

    // associate the oRsp with mock object QueryXXX function
    EXPECT_CALL(oMock,  QueryXXX(_, _)).
        WillOnce(SetArgReferee<1>(oRsp));
    // OK all done

    // call QueryXXX
    XXXRunner oRunner;
    QueryResult oRst = oRunner.DoSomething(oMock);
    …

    // use assertions to verity your expectation
    EXPECT_EQ(“abcdefg”, oRst.attr1);
    ……
}

Summary
GMock provide a series of actions to make it convenient to mock functions, such as SetArgReferee for reference or value, SetArgPointee for pointer, Return for return, Invoke for invoke custom mock function (with simple test logic), you can see here for more details.

Enjoy it :) Thank you
