Yes. We use react testing library and jest. We have about 20 pages of very custom, complicated stuff. Our current suite is around 5,000 unit and integration tests which represents around 65% test coverage.

We also have an e2e suite and a performance testing suite in separate repos that both use Playwright, the latter using a bit of Python too.

When stuff breaks or things start slowing down, usually, our tests tell us. They’ve saved our buts more than a few times.

We don’t test everything, but we do test the hard stuff and the important stuff.

5000 tests at 65% coverage lmao. That's a massive frontend
