Testing is a core part of the Ember framework and its development cycle.

Let's assume you are writing an Ember application which will serve as a blog. This application would likely include models such as user and post. It would also include interactions such as login and create post. Let's finally assume that you would like to have automated tests in place for your application.

There are two different classifications of tests that you will need: Acceptance and Unit.

Acceptance Tests

Acceptance tests are used to test user interaction and application flow. With the example scenario above, some acceptance tests you might write are:

  • A user is able to log in via the login form.
  • A user is able to create a blog post.
  • A visitor does not have access to the admin panel.

Unit Tests

Unit tests are used to test isolated chunks of functionality, or "units", without worrying about their dependencies. Some examples of unit tests for the scenario above might be:

  • A user has a role
  • A user has a username
  • A user has a fullname attribute which is the aggregate of its first and last names with a space between
  • A post has a title
  • A post's title must be no longer than 50 characters

Testing Frameworks

QUnit is the default testing framework for this guide, but others are supported through third-party addons.


The Ember testing guide provides best practices and examples on how to test your Ember applications. If you find any errors or believe the documentation can be improved, please feel free to contribute.
