Webstorm and Karma in Ubuntu 12 LTS

If you are attempting to run Karma unit tests from Webstorm in Ubuntu 12LTS you may run into the following error:

Cannot start Chrome
 Can not find the binary google-chrome

Attempting to export CHROME_BIN=/usr/bin/chromium-browser worked great for running karma from the command line, but did not fix my issue when running it from within Webstorm, so after a bit of searching I found that you can add environment variables to webstorm by editing the Run/Debug Configurations for Karma:

2. Select Karma > karma.conf.js 
3. Add the Environment Variables:

   CHROME_BIN=<path to chromium-browser>

     which chromium-browser
