title: How to test custom template tags in Django?
body: <p>I'm adding a set of template tags to a Django application and I'm not sure how to test them.  I've used them in my templates and they seem to be working but I was looking for something more formal.  The  main logic is done in the models/model managers and has been tested.  The tags simply retrieve data and store it in a context variable such as</p>
  
  <pre><code>{% views_for_object widget as views %}
  """
  Retrieves the number of views and stores them in a context variable.
  """
  # or
  {% most_viewed_for_model main.model_name as viewed_models %}
  """
  Retrieves the ViewTrackers for the most viewed instances of the given model.
  """
  </code></pre>
  
  <p>So my question is do you typically test your template tags and if you do how do you do it?</p>
