Why Can’t PHPUnit UnitTest My WordPress Website

Unit tests for WordPress are a tricky thing. If you need to test the code with a live database, etc. I would suggest using the official WordPress test suite. I’ve gotten unit tests running for a plugin using that method before, but it wasn’t pretty, and was fairly unreliable. If you need to do it … Read more
