A question regarding accessing private or protected variable

[mizhang]

I am new to this test framework. Wondering what is the standard way to access private or protected variables or functions to test in this framework. Didn't find useful results form google, so asking it here.

Thanks a lot!

lest has no support for directly accessing private or protected members.

You may test :

1. indirectly via the public interface
2. by extracting more involved code into it's own class with a public interface
3. via a derived class (for protected members), struct TestClass : TestedClass { using protected_function; };
4. via injecting the likes of friend class Tester;
5. ...

Refrain from doing

#define protected public
#define private public
#include "foo.hpp"

If foo.hpp happens to #include stuff, especially something from std it can easily backfire.
