React Testing Library

This one gives Claude 43 rules across 9 priority-ranked categories for writing React Testing Library tests the right way. It's built around the testing library philosophy of querying by role and label text instead of test IDs, using userEvent over fireEvent, and avoiding implementation details. The rules cover the critical stuff like query selection and async handling first, then work down to accessibility testing. Useful when you're writing new component tests, reviewing PRs for anti-patterns, or trying to remember whether to use findBy or waitFor with getBy. The categorization by impact level is smart because it tells you what actually matters versus what's just polish.
