In this recipe, we'll make use of the
mocha-test (0.11.0), and
contrib-copy (0.5.0) plugins to run our automated Mocha tests, while at the same time, generating coverage reports for the source code they run against.
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.
The following steps take us through creating a sample code base, creating a few tests to run against the code base, and configuring Grunt to generate coverage reports while running the tests.
