Use cases

You have some non-virutal methods needed to mock.

class Demo {
 public:
  int add(int a, int b); /* Need to mock this method */
  int mul(int a, int b, int c); /* Need to mock this method */
  virtual int sub(int a, int b);
};

Mock your functions with macro MOCK_METHOD_EX

#include "gmock-extension.h"

class MockDemo : public Demo {
 public:
  MockDemo(){};
  MOCK_METHOD(int, sub, (int a, int b));
  MOCK_METHOD_EX(int, add, (int a, int b)); /* Same style as google mock */
  MOCK_METHOD_EX(int, mul, (int a, int b, int c));
};

Used EXPECT_CALL_EX, ON_CALL_EX to setup your method's behavior.

TEST_F(DemoTest, TestAdd) {
  EXPECT_CALL_EX(*mMock, add(_, _)).WillOnce([] { return 10; });
  EXPECT_EQ(10, mMock->add(2, 3));
}
