title: Run unit tests with Karma on specific browser versions
body: <p>For reference, I'm running on Windows 8.1.  I'm using Karma to run my unit tests, and I'd like to have them run on multiple versions of a browser.  The Karma documentation for browsers says it's possible to use a script to define custom browsers (<a href="http://karma-runner.github.io/0.12/config/browsers.html" rel="nofollow">http://karma-runner.github.io/0.12/config/browsers.html</a>).  I also came across a GitHub issue that suggested using a script to explicitly run specific browser versions.  I've tried this, using some info I found in <a href="https://github.com/karma-runner/karma/issues/796" rel="nofollow">this thread</a> and installing the karma-script-launcher plugin.  My script is, I believe, identical to the previously linked issue:</p>
  
  <pre><code>"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe" "%1"
  </code></pre>
  
  <p>I'm seeing, however, the same issue; my URL simply has "?id" rather than "?id=1234".  </p>
  
  <p>First, is this a viable way to accomplish my goal, or is there another, perhaps more straightforward, way of testing on multiple browser versions?</p>
  
  <p>Second, assuming this is the ideal solution, where am I going wrong with my batch file?</p>
