Test coverage vs test quality: what a green build never tells you
Every test was green. Yet, we still lost an afternoon figuring out why production was down. That afternoon changed how I think about software quality."

Advice from another engineer, not a guru
I’m an experienced software engineer focused on AI-assisted testing and software quality. I’m not an AI influencer, and I don’t sell hype. I write about what actually changes in engineering work when AI enters the loop.
CORE THESIS
AI changes engineering workflows, not just coding speed. The faster you generate code, the more your testing and quality processes matter.
Every article is grounded in my own projects: the setups I use, the experiments I run, and the mistakes I make so you don’t have to.

What happens with your address
It goes to me, Thomas Langhorst, and to Brevo, who send the emails. It is used for the occasional emails about testing and code quality you just asked for, and for nothing else. Whether you open those emails and what you click in them is measured, which is what the second sentence of the box is about. You can unsubscribe at any time with one click, which is as easy as subscribing was. Your signup and your confirmation click are logged, and that record is kept for three years after you unsubscribe so the consent can still be proven. Nothing is shared with anyone else and nothing is sold. Full detail in the privacy policy.
You can object to advertising at any time, and the emails stop.
