Welcome to the 304th issue!
Big news! Meta announces a new testing method — Just-in‑Time Tests (JiTTests).
It's a new way of unit testing at scale thanks to the LLM-powered mutation technique.
The idea is simple — let AI generate lots of unit tests to catch possible failures, and then delete them.
Here's a 17-page research paper describing in detail why and how it works.
Also, Ayyaz Zafar summarises it: Meta's JiTTests: How AI Writes 22,000 Tests, Finds 4x More Bugs, Then Deletes Them All.
Happy (just-in-time) testing! 🙂
