Testing private class member in C++ without friend [duplicate]

Answer 1

There's a theory that if it's private it shouldn't be tested alone, if it needs so then it should be redesigned.

For me that's Shi'ism.

On some project people create a macro for private methods, just like:

class Something{
   PRIVATE:
       int m_attr;
};

When compiling for test PRIVATE is defined as public, otherwise it's defined as private. that simple.
