This tutorial describes some very simple TDD / BDD cycles for making a “Hello World!” shortcode plugin for WordPress. If you want to duplicate the code, you’ll need a working WordPress install setup with Codeception. I’ve tested this on Ubuntu 16.04LTS, but it will probably work on any machine that can handle Codception.
This tutorial’s code can be found here on Github. If you already have a WordPress enabled machine, and know you can run Codeception, you should be able to just clone the Github repo.
