Workshop

Accelerating development without losing control

AI-assisted development promises speed, but speed without control breeds technical debt and fragility. This hands-on workshop shows PHP developers how to build the automated safety nets that let you move faster because you trust your quality controls, not in spite of them.

Talk

Test-Driven Security

I argue that security flaws result from a lack of testing, and demonstrate how PHPUnit can help prevent common vulnerabilities, such as SQL Injection or Cross-Site Scripting.

About me

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. As a co-founder of thePHP.cc, I help teams in training courses and through consulting and coaching with everything related to PHPUnit, with quality gates for working with LLM-based coding agents, and with supply chain security.

I helped start the PHP Foundation and serve on its board. I have also represented the interests of Open Source at the European Commission and am active in the Open Source working group of the German Informatics Society (Gesellschaft für Informatik).

Where you can meet me next is listed under events. The next dates of my training courses are in the training overview.
