title: Tell Travis to skip a test, but continue to include it in my main test suite?
body: <p>I am using Django 1.8 and I have a management command that geocodes some items in my database, which requires an internet connection. </p>
  
  <p>I have written a test for this management command. However, the test runs the script, so it also requires an internet connection. </p>
  
  <p>After pushing the test to GitHub, my CI is broken, because Travis doesn't have an outside internet connection so it fails on this test. </p>
  
  <p>I want to keep this test, and I'd like to continue to include it in <code>python manage.py test</code> when run locally. </p>
  
  <p>However, is there a way I can explicitly tell Travis not to bother with this particular test?</p>
  
  <p>Alternatively, is there some other clean way that I can keep this test as part of my main test suite, but stop it breaking Travis?</p>
