seriously skip my unittest class...even the setUpClass method

def seriously_skip_this_if(condition, reason):
    '''skip the test class (including the setUpClass method

    nose (and friends) will run your setUpClass and tearDownClass methods even
    if you skip those tests using the usual decorators. This decorator
    seriously skips those parts if the class is marked to skip. This is
    described here:

    def class_maker(cls):

        @unittest.skipIf(condition, reason)
        class ClassWithoutSetups(cls):
            __name__ = cls.__name__

            @classmethod
            def setUpClass(c):
                print 'I overrode the setUpClass!!'

        @unittest.skipIf(condition, reason)
        class ClassWithSetups(cls):
            pass

        ClassWithSetups.__name__ = cls.__name__
        ClassWithoutSetups.__name__ = cls.__name__

        if condition:
            return ClassWithoutSetups
        else:
            return ClassWithSetups

    return class_maker


@seriously_skip_this_if(FOO_IS_ON, 'foo is on. Duh.')
class TestMyClass(unittest.TestCase):

    @classmethod
    def setUpClass(cls):
        print 'Doing the actual class setup!'

    def test_my_stuff(self):
        print 'Did the test!'

Sample output:

$ nosetests ./foo.py -sv
Doing the actual class setup!
test_my_stuff (foo.ClassWithSetups) ... Did the test!
ok

----------------------------------------------------------------------
Ran 1 test in 0.000s

OK
$ FOO=1 nosetests ./foo.py -sv
I overrode the setUpClass!!
test_my_stuff (foo.ClassWithoutSetups) ... SKIP: foo is on. Duh.

----------------------------------------------------------------------
Ran 1 test in 0.000s

OK (SKIP=1)

Is it possible to conserve the original class name in the output? For example:

test_my_stuff (foo.TestMyClass) ... Did the test!

vs

test_my_stuff (foo.ClassWithSetups) ... Did the test!

Good idea @iorbitearth. Updated.
