Note: This book was written to take advantage of a library called WebdriverCSS. Unfortunately, support for WebdriverCSS has ended, and therefore many of the examples in the book no longer apply.

In this short book, you will learn how to:

Automate testing of HTML and JavaScript changes.
Keep on top of breaks in your design as they happen during development.
Add this visual regression technique to speed up old project workflows.

Pre-requisites are simply a basic understanding of:

Command line usage (YouTube Refresher)
JavaScript fundamentals such as variables, functions, etc.
Node fundamentals such as installing and requiring modules.
