title: Where is a python real project to be used as example for the unit-test part?
body: <p>I'm looking for a python project to use as example to copy the design of the unit test parts.</p>
  
  <p>The project should have these features:</p>
  
  <ol>
  <li>its code is almost fully unit tested</li>
  <li>the code is distributed in many packages, there are more that one level of packages </li>
  <li>all the test can be run with a single command, for example with <code>python test.py</code></li>
  </ol>
  
  <p>I need that the project should use the same test convention for all the code contained. I saw the whole python project but the the various packages are tested with different conventions. For example the setuptools packages uses an ad hoc adaption of unittest library while the other packages doesn't. </p>
  
  <p>I need that the project doesn't use a ad-hoc or a highly customized testing framework, because I want reuse its test architecture in my project.</p>
