This talk was given at php[tek] 2017.
This isn’t a talk about adding tests to your PHP codebase, but adding tests to the PHP language itself. And the best part is, all the tests are written in PHP, so you don’t even have to dust off your old C book from college. In this talk, I will show you how to find untested parts of the PHP source code, how to write a test, and how to submit your tests to PHP internals. Just think, even without any C programming, you’ll be able to call yourself an internals contributor.
