GTest测试用例“EXPECT_CALL”编译错误

Question

#include "gtest\gtest.h"
using namespace testing;

class MyGTest : public Test
{
public:
    void f(){}
    void g(){
        f();
        f();
    }
};

TEST_F(MyGTest, first)
{
    EXPECT_CALL(*this, f()).Times(2);
    g();
}

VC2013 says:

    "MyGTest_first_Test" has no member "gmock_f"

What does it mean? I expect the call to g() to call f() for 2 times. Any syntax error I made?

Answer 1

Not a syntax error, more like a completely wrong approach. Macro EXPECT_CALL is used to set expectations of function calls from mock objects. The problem is that you are not passing a mock object to EXPECT_CALL (an object of class whose definition contains MOCK_METHODN ), you are dereferencing this pointer instead. In doing so, you are passing an object of your test class to EXPECT_CALL . This is why the compiler error mentiones class MyGTest_first_Test , gmock creates a new class in the background, and its name is a combination of fixture class name ( MyGTest ), test case name ( first ) and base class name ( Test ).
