copied!<p>I am still using Django 1.2.1, and I think with the newer Django we don't <code>import unittest</code> and then do <code>unittest.TestCase</code>.</p> <p><strong>Illustration</strong></p> <pre><code>import unittest class TestThis(unittest.TestCase): from django.utils.unittest import TestCase class TestThis(TestCase): from django.test import TestCase class TestThis(TestCase): </code></pre> <p>According to <a href="http://pycon-2012-notes.readthedocs.org/en/latest/testing_and_django.html" rel="noreferrer">PyCon2011 talk</a>, the second one is <strong>slightly</strong> more efficient. </p> <p>Here is the <a href="https://docs.djangoproject.com/en/dev/topics/testing/#testcase" rel="noreferrer">diagram</a> showing the relations:</p> <p><img src="https://i.stack.imgur.com/YyqWD.png" alt="enter image description here"></p> <p>So <code>django.utils.unittest</code> and <code>django.test</code> inherit from either <code>unittest</code> or <code>unittest2</code>.</p> <p>I am not sure if the following is correct or not. Please help editing.</p> <pre><code> ________________________________________________________________ | Name | Django Version | Python Version | ----------------------------------------------------------------- | unittest | >= 1.0 | >= 2.6 | ----------------------------------------------------------------- | django.utils.unittest | >= 1.3 | ?? | ----------------------------------------------------------------- | django.test | >= 1.0 | >= 2.6 | | - SimpleTestCase >= 1.4 >= 2.7 | | - LiveServerTestCase >= 1.4 >= 2.7 | ----------------------------------------------------------------- </code></pre> <p>In terms of efficiency, which one of the three is better? Many Django developers mock when they test, so sometimes database are not even necessary. Is there a way not creating tables when we run <code>manage.py test myapp.MyClass</code> ? For older version (prior to 1.3), which one is better? </p>
