title: Check if the component action gets called in an integration test
body: <p>I have the following simple component:</p>
  
  <pre><code>export default Ember.Component.extend({
    actions:{
      someAction(){
        //...
      }
    }
  });
  </code></pre>
  
  <p>What should I do(in an integration test) if I want to check if this action gets called in the corresponding <code>hbs</code> file?</p>
