Module introduction

Welcome to module number 3, "API unit testing with Mocha".

One of the important aspects of enterprise apps is that they should be reliable and easy for developers to add to.

For that reason it's important to provide tests for the key functionality.

So in this module, we'll be creating more endpoints for our API, but we'll also be creating unit tests for them as well.

So we'll begin with a brief introduction to unit testing and the Mocha JavaScript testing framework.
