If you end up in such situations, your classes are probably too big and try to do too much in one thing.

Also if you look at it in different manner, private members are part of the logic of the classes, which means not testing them could create logic bugs (what i call smart bugs) and refactoring them into public member would expose a lot of the guts of the implementation.
