Testing controllers

Controllers should be tested in your application. In this recipe, we'll test some basic actions from a controller.

How to do it...

1. Create a new index controller:

   $ ember g controller index
   

   This creates a new controller called index.

2. In the index controller, add a new property and action:

   // app/controllers/index.js
   import Ember from 'ember';
   
   export default Ember.Controller.extend({
       myValue: 'value',
       actions:{
         pressed(value){
           this.set('myValue',value);
         }
       }
   });

   This controller has one property named myValue. Another action called pressed changes the value of myValue to whatever value is passed in the function.

3. Update the index unit test. Add a few tests for the action and property:

   // tests/unit/controllers/index-test.js import { moduleFor, ...
