In my tests, it does not appear possible to use the auto_unit_test.hpp
macros in a test class that is attempting to be a friend of a testee
class. The compiler complains that the test class is trying to access
private data. Does anyone know how to make them work together?
(Should this be a separate thread, or is it alright to add it to this one?)
