title: How to focus/blur on a component in ember integration tests?
body: <p>How can I trigger focus and blur events while testing an Ember.js component? </p>
  
  <p><code>this.$().focus();</code> or <code>this.$('input').focus();</code> seems working but behaves different in phantomjs and chrome.</p>
  
  <p>Also <code>this.$().blur();</code> or <code>this.$().focusout();</code> seems not working both phantomjs and chrome.</p>
