title: django 1.6 app tests.py to tests subdirectory
body: <p>with django 1.6, I have a django app with tests.py file</p>
  
  <pre><code>app
  - tests.py
  </code></pre>
  
  <p>in this file I tested some management functions </p>
  
  <pre><code>from management.commands.getevents import some_function
  </code></pre>
  
  <p>when I try change the tests.py to a tests directory with differents tests files</p>
  
  <pre><code>app
  - tests
  -- __init__.py
  -- test_models.py
  -- test_views.py
  -- test_managements.py
  </code></pre>
  
  <p>and I try running the test</p>
  
  <pre><code>python manage.py test
  </code></pre>
  
  <p>get this error </p>
  
  <pre><code>ImportError: Failed to import test module: events.tests.test_managements
  ...
  ImportError: No module named management.commands...
  </code></pre>
  
  <p>with the directory of test files, why django don't see the management module ? </p>
