title: Run protractor tests with different window sizes?
body: <p>I want to start 4 different chrome windows to run the same tests on 4 resolutions. –</p>
  
  <p>I know protractor has a feature called multiCapabilities, and I know you can set the window size like this: 
  <code>browser.manage().window().setSize(320, 480);</code></p>
  
  <p>But I don't really find a way to combine these 2. Or is there an easier way to create this behaviour</p>
