title: Karma runner does not run all files
body: <p>For some weird reason that I cannot fathom, my karma runner sometimes does not run all the test files.</p>
  
  <p>karma.conf.js:</p>
  
  <pre><code>module.exports = function(config) {
  config.set({
  
      basePath: '',
      frameworks: ['jasmine'],
  
      files: [
          '../lib/angular/angular.min.js',
          '../lib/angular-mocks/angular-mocks.js',
          '../lib/angular-notify/dist/angular-notify.min.js',
          '../lib/JsCollection/dist/jscollection-0.1.5.min.js',
          '../lib/lodash/dist/lodash.min.js',
          'node_modules/jasmine-ajax/lib/mock-ajax.js',
          'app/**/*.js',
          'tests/**/*.js'
      ],
  
      plugins: [ 'karma-jasmine', 'karma-phantomjs-launcher'],
      reporters: ['progress'],
      port: 9876,
      colors: true,
      logLevel: config.LOG_INFO,
      autoWatch: true,
      browsers: ['PhantomJS'],
      singleRun: false
  });
  };
  </code></pre>
  
  <p>So here is what happens, I run my tests and everything starts out just fine:</p>
  
  <pre><code>oli@devone:~/projects/2bi/public/src$ karma start
  03 06 2016 11:40:44.861:WARN [karma]: No captured browser, open http://localhost:9876/
  03 06 2016 11:40:44.921:INFO [karma]: Karma v0.13.22 server started at http://localhost:9876/
  03 06 2016 11:40:44.967:INFO [launcher]: Starting browser PhantomJS
  03 06 2016 11:40:46.764:INFO [PhantomJS 2.1.1 (Linux 0.0.0)]: Connected on socket /#qmOPHCmxWaFWMmvrAAAA with id 14003688
  PhantomJS 2.1.1 (Linux 0.0.0): Executed 46 of 46 SUCCESS (0.708 secs / 0.888 secs)
  </code></pre>
  
  <p>So my 46 tests are executed normally, everything is fine and dandy. Then I start to code and karma starts behaving weirdly, it does not run all the tests sometimes, but sometimes it does. Often it gets stuck on only running say 16 tests so I have to restart it to run all the tests again.</p>
  
  <p>Here I change the formula test a few times:</p>

  <p>Everything is run on a virtualbox machine but the filesystem is local.</p>
  
  <p>Anybody have any idea what is going on?</p>
