title: django tests folder outside app
body: <p>In django i have built an app, </p>
  
  <p>at the moment the file structure looks as such:</p>
  
  <ul>
  <li>doc
  <ul>
  <li>documention here</li>
  </ul></li>
  <li>app
  <ul>
  <li>tests</li>
  <li>admin.py</li>
  <li>...</li>
  </ul></li>
  </ul>
  
  <p>To match the layout the company is using for other non django projects i would like to make the structure as so:</p>
  
  <ul>
  <li>doc
  <ul>
  <li>documention here</li>
  </ul></li>
  <li>app
  <ul>
  <li>admin.py</li>
  <li>...</li>
  </ul></li>
  <li>tests</li>
  </ul>
  
  <p>preferably i would like the command ./manage.py test [app] to run these tests
  Can anyone give me an idea of how i could go about this?</p>
