CCATP #715 – Bart Busschots on PBS 135 of X – Introducing Jest (and re-Introducing Test Driven Development & Unit Testing)

In this week’s installment of Programming By Stealth, Bart takes us down memory lane to 102 episodes ago when he first introduced us to the concept of test-driven development. He explains why back then he taught us how to use QUnit for our TDD work, and why it’s no longer in favor with him. It’s not just the advancements in technology like ES6, but it’s also because QUnit makes it terribly hard to write tests and to interpret what you’ve written when you’ve been away from it for a while. He walks us through his criteria for picking a new TDD tool, and why he chose Jest for the job.

He then walks us through a worked example of how to write some simple tests on a module and of course, explains how Jest does its job running our tests. I liked it, even though my head hurt during a bit of it!
