This year I’ve started to use Codeception as an alternative to vanilla PHPUnit for testing WordPress plugins. I’m using the fantastic WP-Browser library written by Luca Tumedei. It makes writing WordPress acceptance tests sane by providing a suite of Codeception Modules to load WordPress and simulate WordPress APIs.
At iThemes we host all of our repositories on Bitbucket which made Bitbucket Pipelines a natural choice for automatically running our Codeception tests on commit. Getting everything up and running took a bit of work and wasn’t always straightforward. I intend for this post to be a guide to testing WordPress plugins with Codeception on Bitbucket Pipelines that’ll hopefully save you some time if you’re trying to set this up for yourself.
