Unit test accessing private variables

Question

I have a unit test class Tester; I want it to access private fields of a Working class.

class Working {
    // ...
    private:
            


        

Answer 1

If you absolutely must do this, you could conditionally compile your code so that TestBase is a friend only when unit testing:

class Working {
    // ...
    private:
    int m_variable;

#ifdef UNIT_TESTING
    friend class TestBase;
#endif
};
