You mean by deriving my class_to_test with derived_class and wraping the 
protected class_to_test::method_to_test by a public method in derived_class?

That's possible, but I didn't like that. Because if I'm precise I only test 
the public method of derived_class that way ;-) But if nothing works, I will 
do that.

To return to your previous posting:
I try to do my best and test only public method. But sometimes it's very hard, 
especially for complex protected methods. Either you use the way descripted 
above or you move the method to a helper class. Both alternatives are not 
elegant I think.
