title: Is there a standard way to store test coverage results to compare them in time?
body: <p>I have a Django project in which I can run coverage and create the report</p>
  
  <pre><code>coverage run --source='.' manage.py test my_app
  </code></pre>
  
  <p>I would like to compare the results over time after code refactors.  Is there a way to achieve this without creating my own data model?</p>
  
  <p>Thanks in advance,</p>
