How to mock a dictionary in Python
<p>Let's say I have a function like this:</p>

<pre><code>def do_something(dict_obj):
   # access to the dict_obj then do some stuff
   eg.
   if dict_obj['doors']:
      do_something_with_doors()
   map_car_make(dict_obj['make'])
   ...

   if dict_obj['is_active']:
        do_something_else()
</code></pre>

<p>I want to mock the <code>dict_obj</code> to have <code>is_active</code> element and don't care the rest, how do I do that?</p>
