Users don't use data-testid, so why do your tests?
Testing can be fun, actually
Writing and maintaining tests is boring. But they're also some of the most valuable code we can write. With this blog post you'll learn a criminally underrated testing technique to add to your testing toolbox that can make tests a whole lot more pleasant.

Your SPA Is Leaking Memory. Soak Test It
Some teams force-reload their single-page web apps (SPAs) every few hours just to clear the memory the app leaked. A Playwright soak test finds the leak instead.

Tests Are The New Moat | Daniel Saewitz
As AI becomes better at cloning people's open source work, what ends up becoming most valuable are software contracts, tests, and API surface area. This clashes the incentives of clearly defining your commercialized open source software with protecting it.
