[issue32071] Add py.test-like "-k" test selection to unittest

[Jonas H.]

Jonas H. <jonas at lophus.org> added the comment:

Ah, the problem isn't that it's running getattr() on test methods, but that it runs getattr() on all methods.

Former code: attrname.startswith(prefix) and \
                callable(getattr(testCaseClass, attrname))

New code: testFunc = getattr(testCaseClass, attrname)
            isTestMethod = attrname.startswith(self.testMethodPrefix) and callable(testFunc)

This is trivial to fix. @Core devs: Should I revert to original behaviour with the order of the prefix check and the getattr() call, and add a regression test that guarantees this behaviour?
