Ember.js Cookbook

Using unit tests

Unit tests are used to test smaller chunks of functionality. In this recipe, we'll see an example of this.

How to do it...

In this example, we'll create a simple Ember.Object with a computed property. We'll test this computed property and assert if the value returned is correct or not.

       firstName: 'John',
       lastName: 'Smith',
       fullName: Ember.computed('firstName', 'lastName', function() {

         const lastName= this.get('lastName');
         return `Full Name: ${firstName} ${lastName}`;
