What it does
Pest is a Testing Framework with a focus on simplicity. It was carefully crafted to bring the joy of testing to PHP.
Pest is the elegant PHP testing framework built for developers and AI agents — with browser testing, AI evals, an agent browser that verifies your coding agent
Pest brings the joy of testing to PHP — for you and your coding agents. Browser testing and AI evals are built in, and agents verify their own work, end to end. Test Impact Analysis maps your whole suite to the code each test depends on, so a change to one file re-runs only the tests it can break. A 15-second suite comes back in under a second, fast enough for an agent to run it after every edit. A failed test prints the assertion, the diff and the exact line of code in your terminal. Most of the time you know the fix before you open the editor. Parallel execution, coverage, mutation and snapshots ship in the box. You install Pest once and stop assembling a toolchain.

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
