body: <p>Is it possible to modify/patch an unittest of odoo?</p>
  <p><strong>E.g.:</strong>
  In the test case <em><strong>test_10_perf_sql_blog_standard_data</strong></em> in the <em>/addons/website_blog/tests/test_performance.py</em>, how can I modify it to <em>self.assertEqual(self._get_url_hot_query('/blog'), <strong>31</strong>)</em>?</p>
