For Django 1.8+, you should use TestCase.setUpTestData instead of TestCase.setUpClass.

class MyTests(TestCase):

    @classmethod
    def setUpTestData(cls):
        # Set up data for the whole TestCase
        cls.foo = Foo.objects.create(bar="Test")

    def test1(self):
        self.assertEqual(self.foo.bar, 'Test') 

The documentation is here.
