title: Karma - Jasmine : Show line number when test failed
body: <p>Is it possible to print the line number of the expect that failed ?</p>
  
  <p>I'm using grunt to launch karma test (jasmine configuration) of my angularjs application).</p>
  
  <p>Currently, the console log show, for example, "Expected true to equal false." and the "describe" and "it" who it comes from... But I have a lot of expect by "it" asset so it's not easy to find the "wrong" line.</p>
  
  <p>Thanks</p>
