In this chapter, we reviewed the basics of Backbone.js applications and introduced the Notes application as a helpful, if optional, companion to the test examples in this book. We then reviewed some relevant high-level testing concepts and dived into the specifics of what we will want to test in a Backbone.js application—in separated application pieces and as integrated parts of a whole. Finally, we wrote our first application unit tests and extended the test infrastructure from Chapter 1, Setting Up a Test Infrastructure, to execute our test reporter.

You should now be able to take an existing or in-development Backbone.js application, analyze its components, and create an abstract test infrastructure outline that will later be filled in with actual tests and suites.

In the next chapter, we will learn about Chai assertions, basic Mocha test constructs (specs and suites), test setup/teardown/configuration, and how to deterministically verify behavior in an asynchronous application...
