title: testing click python applications
body: <p>click is a python package for creating nice commandline interfaces for your applications. I have been playing with click a bit and today pushed this <a href="https://github.com/jetbird/toroman" rel="noreferrer">simple</a> roman numeral converter on github. </p>
  
  <p>What I want to do now is to test my click application. I am reading through the documentation, but don't know how to run the tests.</p>
  
  <p>Does anyone have experience with testing click applications?</p>
