title: Can Python's unittest test in parallel, like nose can?
body: <p>Python's NOSE testing framework has the concept of <a href="https://nose.readthedocs.io/en/latest/plugins/multiprocess.html" rel="noreferrer">running multiple tests in parallel</a>. </p>
  
  <p>The purpose of this is not to test concurrency in the code, but to make tests for code that has "no side-effects, no ordering issues, and no external dependencies" run faster. The performance gain comes from concurrent I/O waits when they are accessing different devices, better use of multi CPUs/cores, and by running time.sleep() statements in parallel.</p>
  
  <p>I believe the same thing could be done with Python's unittest testing framework, by having a plugin Test Runner.</p>
  
  <p>Has anyone had any experience with such a beast, and can they make any recommendations?</p>
