title: Using Travis CI for testing on UNIX shell scripts
body: <p><strong>Background:</strong></p>
  
  <p>I have been using Travis CI for my PHP projects and I really like how they give you a link to a picture that shows the status of the current build of your project.</p>
  
  <p>I am currently making a lot of tools using UNIX shell scripting and would like to use Travis CI to test my UNIX scripts. </p>
  
  <p>I have searched the internet trying to find out how to achieve this. I went to the main website, searched Stackoverflow as well as did a bit of Google searching.</p>
  
  <p>It seems like this isn't possible.</p>
  
  <p>I currently use <strong>shunit2</strong> to test my shell scripts and functions.</p>
  
  <p><strong>My question(s) is/are:</strong></p>
  
  <ol>
  <li>Is it possible to use Travis CI to test shell scripts?</li>
  <li>If not are there any alternatives that I could use that plug into GitHub?</li>
  <li>What is the best way to perform integration testing on shell scripts?</li>
  </ol>
