Sebastian Bergmann

PHPUnit Creator Open Source Advocate Testing Expert International Speaker

"Hello, I'm Sebastian. I've been experiencing PHP for over 25 years and know exactly how the fear of legacy code and the associated frustration feels. It's my mission to help teams overcome these fears and enjoy developing again.

As the creator and main maintainer of PHPUnit, I offer you first-hand knowledge. My expertise, grown from decades of experience, numerous technical books, international talks, and my commitment as a founding member of the PHP Foundation, flows directly into our collaboration.

I live the open-source philosophy of shared learning and transparency. Together we create a testing culture that puts trust and confidence at the center."

What your test run already knows

On every run, PHPUnit knows how long each test took, how much memory it used, and why it failed. Most of that evaporates. otr-report reads it back out of the Open Test Reporting logfile and puts it within reach.
