Generating coverage reports for client-side code using QUnit and Istanbul

In this recipe, we'll make use of the qunit-istanbul (0.4.5) plugin to run our automated QUnit tests in a PhantomJS environment, generating coverage reports for the source code they run against using the Istanbul library, and comparing the results against a specified threshold.

Getting ready

In this example, we'll work with the basic project structure we created in the Installing Grunt on a project recipe in Chapter 1, Getting Started with Grunt. Be sure to refer to it if you are not yet familiar with its contents.

How to do it...

The following steps take us through creating a sample code base, creating a few tests to run against it, and configuring Grunt to generate coverage reports and compare the results to a threshold.

  1. We'll start by installing the package that contains the qunit-istanbul plugin by following the instructions provided in the Installing a plugin recipe in Chapter 1, Getting Started with Grunt.

  2. Then, we...
