title: browserify, karma, jasmine and gulp not running tests even after setting config
body: <p>I followed the instructions here <a href="https://www.npmjs.com/package/karma-browserify" rel="nofollow">https://www.npmjs.com/package/karma-browserify</a> and even after setting the karma.conf.js with the following it does not run any tests in PhantomJS or Chrome. It says <code>Executed 0 of 0 ERROR</code> even though I have one dummy spec file in test folder which passes.</p>
  
  <pre><code>  karma.set({
      basePath: 'to/some/somepath'
      frameworks: ['browserify', 'jasmine' ],
      files: ['relative/to/somepath/test/**/*.js'],
      preprocessors: {
        'relative/to/somepath/test/**/*.js': ['browserify']
      },
  
      browserify: {
        debug: true
      }
    });
  </code></pre>
