The official way of running the WordPress testsuite is horribly complicated and prone to user error. Touchstone fixes both of those issues by making the process of creating and running tests easy.
I've been building WordPress themes and plugins since 2009. 13 years is long time to be building on top of a framework that has no real ideology when it comes to testing.
In 2019 I started to look at ways of writing unit and integration for my WordPress theme and plugins. To cut a long story short, the process was more pain inducing than I could've ever realised.
What makes writing tests for WordPress plugins and themes so difficult?
In 2021, nearly two years after first attempting to write tests for anything in WordPress, I knew the solution: To build my own test runner that sits on top of PHPUnit and WordPress.
Touchstone is my solution to the many WordPress testing issues I've faced myself.
It provides a simple API which fixes the biggest issue of all, getting set up. To do all the setup steps required to run your tests, simply run:
./vendor/bin/touchstone setup --db-host=127.0.0.1:8889 --db-name=touchstone_tests --db-user=root --db-pass=root
Provide it with the relevant info for your local database and it'll do the rest.
You can also pass it a unix socket (helpful if you use something like Local):
To run your tests, you run:
# All tests ./vendor/bin/touchstone test # Unit tests ./vendor/bin/touchstone test --type=unit # Integration tests ./vendor/bin/touchstone test --type=integration
If you like the sound of no longer fighting WordPress for hours on end just to get the testing environment set up, then please give Touchstone a go.
If you've tried it, please let me know what you think!
