Testing Stimulus

Since the official Stimulus handbook doesn't include testing, and I recently had to cover a Stimulus controller with tests, I'd like to share my approach. Install dependencies The first step is installing the required npm packages to make this work. yarn add --dev jest yarn add --dev babel-jest babel-preset-es2015 yarn add --dev mutationobserver-shim We're going to use Jest for testing; Babel pack
