Last year's PHPUnit 10 was the most significant update to the PHP world's most widely used test runner. This year's PHPUnit 11 refined many of those changes, and next year's PHPUnit 12 will finally remove a lot of old and messy code.
This is a good time to take stock, and this presentation is the perfect opportunity to do so. You will learn everything you need to know about PHPUnit 10 and PHPUnit 11, how to prepare for PHPUnit 12 today, and perhaps most importantly, which parts of PHPUnit you can safely ignore and forget.
I most recently presented “PHPUnit 10-12: What to know and what to forget” at betterCode() PHP on . Previous events include TYPO3 Developer Days.
I am Sebastian Bergmann. I started writing PHPUnit in 2000 and still maintain it. In the same year I gave my first talk at a PHP conference. PHPUnit has been installed more than a billion times from Packagist, and a new major version comes out every February.
As a co-founder of The PHP Consulting Company (thePHP.cc), I work with teams on their tests: on test strategy and test design, on testable code, on fast test runs and on upgrades to current versions of PHPUnit. More on this under consulting and coaching.
Where you can meet me next is listed under events. The next dates of my training courses are in the training overview.
On , I will be in Frankfurt am Main at the PIMCORE Community Dev Days. There I will give the presentation “Speed is a byproduct of trust”.
