Testing django auth'd URLs using Factories to create users

I've been using FactoryBoy to setup objects for my tests and now would like to test @login_required URLs so I've created 3 user factories; StandardUserFactory, StaffUserFactory, SuperUserFactory which are all fairly similar to this;

class StandardUserFactory(DjangoModelFactory):
    """
    Standard user factory.
    """
    class Meta:
        model = User
        django_get_or_create = ('username', )

    username = factory.Sequence(lambda n: u'stdaccount{}'.format(n))
    first_name = u'Standard'
    last_name = factory.Sequence(lambda n: u'Account{}'.format(n))
    email = factory.lazy_attribute(
        lambda u: '{}.{}@test.com'.format(u.first_name, u.last_name)
    )
    password = factory.PostGenerationMethodCall('set_password', 'password')
    is_staff = False
    is_active = True
    date_joined = str_now()

Then in my test case I'm doing this to try and test that the views you are required to login for work but after the client login I still get a 302;

class TestArticlesViews(TestCase):
    def setUp(self):
        self.user = StandardUserFactory.create()
        self.staff = StaffUserFactory.create()
        self.super = SuperUserFactory.create()
        self.client = Client()
        self.event1 = EventFactory(date='2015-01-10')
        self.event2 = EventFactory(date='2015-01-15')
        self.event3 = EventFactory(date='2015-03-20')

    def test_add_form(self):
        # Issue a GET request.
        response = self.client.get('/events/add/')

        # Check that the response is 302 login require redirect.
        self.assertEqual(response.status_code, 302)

        login = self.client.login(
            username=self.staff.username, password='password'
        )
        self.assertTrue(login)

        # Issue a GET request.
        response = self.client.get('/events/add/')

        # Check that the response is 200 following login.
        self.assertEqual(response.status_code, 200)

Is this way of logging in within a TestCase correct?
