Difference using class and unittest class with nose

Question

I'm writing some tests and test them with nosetests

All my tests are in multiples classes from object, and I try to access to the test name (like test_ipam_get.TestIPAMGet.test_noAuth).

Example test class :

class TestIPAMGet(object):
    @classmethod
    def setup_class(cls):
        app.config['TESTING'] = True
        cls.web = app.test_client()

    @classmethod
    def teardown_class(cls):
        pass

    def test_noAuth(self):
        client = self.web.get('/api/v0.1/')
        assert_equal(client.status_code , 401)

Nose produce me this output :
test_ipam_get.TestIPAMGet.test_noAuth... ok

I tried to access to the test name. According to A way to output pyunit test name in setup(), I can inherit from unittest.Testcase and use self.id() and it works. But now, my nose output change to :
test_noAuth (test_ipam_get.TestIPAMGet) ... ok

1. Can you explain why and what's the difference ?
2. Is it possible to get the test name without using the inheritance ?
