Kahlan – A Next-generation Test Framework for PHP (github.com)

the best test framework I've ever seen

I've used Kahlan, it's sped up my test writing massively. I feel a lot more productive and less frustrated. It's also blazingly fast and the code coverage is MUCH quicker than PHPUnit/XDebug!

PHP without Kahlan is like going to the office with no pants. It's been invaluable to improving our team's code reliability.
