Solve the following python programming problem given the following code:
@ nottest 
def test_generator(test_name, skip = False) : 
    @ softer_assert 
    def test(self) : 
        if skip : 
            self.skipTest (skip) 
self.build_case_structures (test_name) 
        desired_cases = self._get_test (test_name).get ('outcome', []) 
        undesired_cases = [case for case in self.ALL_CASES if (case not in desired_cases)] 
        sync_log = get_properly_wrapped_sync_log (self.sync_log._id) 
        self.assertEqual (sync_log.case_ids_on_phone, set (desired_cases)) 
        assert_user_has_cases (self, self.user, desired_cases) 
        assert_user_doesnt_have_cases (self, self.user, undesired_cases) 
return run_with_all_backends (skip)
