title: Accessing Django test client in setUpClass
body: <p>I have a test class where I would like to create and login a user once:</p>
  
  <pre><code>class UserModelTest(TestCase):
      fixtures = ['group_perms']
  
      @classmethod
      def setUpClass(cls):
          cls.standard_user = UserFactory(first_name='Firsto', last_name='Namo')
  
      @classmethod
      def tearDownClass(cls):
          cls.standard_user.delete()
  
      def setUp(self):
          self.moderator = ModeratorFactory() # I'm here because I need access to fixtures to work - but I'd rather be in setUpClass
          self.client.login(email=self.moderator.email, pass='pass') # I'm here because I need access to self.client to work - but I'd rather be in setUpClass
  </code></pre>
  
  <p>So my question (or two):</p>
  
  <ul>
  <li><p>Can I move the moderator into the <code>setUpClass</code> method (given it needs
  access to fixtures)?</p></li>
  <li><p>Can I access <code>self.client</code> in <code>setUpClass</code>?</p></li>
  </ul>
