PHPUnit Is Slowness I love PHPUnit don’t get me wrong. More than a testing library, I like testing, or having tests. It’s like the code got yo back bro! Build code that lasts. EDIT: I know most of the problems are inherent with tests not the testing framework. However, my requirements dictate how I use it to a certain extent. Peace. PHPUnit is painfully slow. Seriously. Though. Maybe having a concurrent environment it can run it would help.
