PHP allows extending classes to redefine visibility of methods as long as the new visibility is more permissive; I see no reason to change this, particularly as it's common practice to define these methods as public when writing test cases.

[gag237]

Methods are never called from outside the object, in other words there is no need to be public.

The second argument: from a protected to public can do always, and not the reverse; so get the error: "Access level to setUp () must be public"

Does this cover all occurences?

[gag237]

TestCase these are intended for use outside zf2.
The other TestCase Used for internal testing. Therefore, there is not changed. If you want to change and there - let me know.
