title: django data between tests
body: <p>Is it normal for data be deleted after a test success in django? I'm not talking about for each test run, let me do a example:</p>
  
  <pre><code>class MyFooTest(TestCase):
      def test_foo1(self):
          # Some foo test code here
  
      def test_foo2(self):
          # Some foo test code here
  </code></pre>
  
  <p>The data made during test <code>test_foo1</code> do not existing when test <code>test_foo2</code> is made, is it normal to happens?</p>
