In this chapter, we covered a lot of things. We began with setting up a Node RESTful server that talks to a MongoDB database and returns JSON to the browser. We set up Protractor with an Angular application to cover the e2e tests that are needed as an application gets larger. We also set up Karma to handle testing our specs and generating code coverage on a Backbone application that uses Require.js and CoffeeScript. Finding the correct solution to a problem can sometimes be a difficult task, but with patience and persistence, anything can be done; take this chapter as a welcome to writing better unit tests and creating projects with outstanding code coverage.
