title: Get python unit test duration in seconds
body: <p>Is there any way to get the total amount of time that "unittest.TextTestRunner().run()" has taken to run a specific unit test.</p>
  
  <p>I'm using a for loop to test modules against certain scenarios (some having to be used and some not, so they run a few times), and I would like to print the total time it has taken to run all the tests.</p>
  
  <p>Any help would be greatly appreciated.</p>
