Welcome to the 287th issue!

Playwright has just announced the introduction of Agents!

The three Planner, Generator and Healer test agents are responsible for guiding AI through the core process of building a Playwright test.

Sounds exciting, doesn't it?!

Karthik K.K. has already tried them out and recorded a 30-minute demo, followed by an explanation that while the solution has potential, it may not be ready yet for some use cases.

It's an intriguing move nevertheless and we'll likely see more development and improvements in this area.

Happy testing! 🙂
