title: How can I perform unit test in ember.js ?
body: <p>I've been developing a web application where I'm using ember.js 1.0. I was wondering if there is any way or framework to make unit test in ember.</p>
  
  <p>For instance, suppose that I've a controller called "CustomerController" and I have a method to add need items to a shopping cart. </p>
  
  <pre class="lang-js prettyprint-override"><code>...
  addNewItem : function(item){
      var content = shoppingCart.get("content");
      content.push(item);
      shoppingCart.set("content", content);
  }
  ...
  </code></pre>
  
  <p>So i want to perform a unit test to see if the number of items increase when the customer add a new item. What kind of framework I can used to accomplish this?</p>
