Getting Started with Node.js and Mocha

Mocha is a testing library for Node.js, created to be a simple, extensible, and fast. It’s used for unit and integration testing, and it’s a great candidate for BDD (Behavior Driven Development).

This article will walk you through its installation and configuration, as well as demonstrate its usage by implementing a color converter that can translate from RGB (red, green, blue) to hexadecimal color representation. In addition, we will create a web server that exposes the above converter and demonstrates how to test asynchronous code.
