Running Codeception tests on multiple WordPress environments

Using the –env flag in Codeception. Running tests against multiple versions of WordPress.

Passing Tests!

Suppose you want to run your test suite against multiple environments? Perhaps with different browsers or with different versions of WordPress or PHP? Codeception makes this easy with the –env flag.

This is a plugin I made that rolls back a new feature added to WordPress 4.9. I want to run an acceptance test against the latest version of WordPress, and also against a legacy version of WordPress.

Setup multiple environments

I use an Ubuntu laptop with apache2. Your mileage will vary. When I develop a website, say site.com, I setup my laptop to redirect site.dev to a local directory on my laptop. There I keep a copy of the production site to work on.

Directions to setup multiple hosts from Rackspace.com

On my machine, I setup two distinct WordPress installs, one at http://localhost and the other at http://wp.dev. One running version 4.9 and the other running version 3.9.

WordPress v 3.9.23
WordPress v 3.9.23

WordPress v 4.9
WordPress v 4.9

In this example, I’ll be running an acceptance test against both versions of WordPress. I’ll need to setup the YML file like this:

I use this command:
bin/codecept run acceptance -vvv --html --env remotehost --env localhost

bin/codecept is the executable [might be wpcept or codecept]
acceptance is the suite
remotehost and localhost are the envs
-vvv very very verbose [one dash]
–html report to html [two dashes]

Codeception runs:
