I have a pretty large test suite and I decorated some of the test_* functions. Now I can\'t call them by ./test.py MySqlTestCase.test_foo_double, python3.2 comp
I think the problem is that the decorated function doesn't have the same name and, also, it doesn't satisfy the pattern to be considered a test method.
Using functools.wrap to decorate decorator should fix your problem. More information here.
