In this recipe, we will demonstrate how to configure QUnit and write a variety of tests to verify that our CoffeeScript code is working as expected.
We will begin by downloading the QUnit package and configuring the test runner.
QUnit can be installed in a variety of ways. We will be using Node's bower package installer to grab the QUnit files we need.
Bower is a package manager similar to NPM, but where NPM specializes in server-side packages, bower specializes in frontend packages. To install bower, use the following command:

With bower installed, we can install QUnit using...
