title: phantomjs does not capture karma because socket.io.js is not found
body: <p>I use phantomjs 1.9.16.</p>
  
  <p>When I run my unit tests with karma runnter I am asked to:</p>
  
  <p>"To capture a browser open <a href="http://localhost:9999/tests/" rel="nofollow">http://localhost:9999/tests/</a>"</p>
  
  <p>I do this in my WebStorm 10 IDE and click on the above message to open the default browser.</p>
  
  <p>"Karma - starting" appears then in the browser viewport.</p>
  
  <p>Karma-Server Tab in the WebStrom IDE has this output:</p>

  <p>Is the problem with karma or phantomjs?</p>
  
  <p>Actually it looks to me that => WARN [web-server]: 404: /tests/socket.io/socket.io.js</p>
  
  <p>socket.io.js is not found when I check the source code of the html page under view-source:<a href="http://localhost:9999/tests/" rel="nofollow">http://localhost:9999/tests/</a></p>
