This skill provides specialized guidance for writing high-confidence frontend tests based on the DOM Testing Library philosophy of testing behavior over implementation. It helps developers avoid common pitfalls like false negatives during refactors by focusing on how end-users interact with the DOM. The skill includes deep-dives into query prioritization, realistic user simulations with userEvent, complex asynchronous testing patterns, and network-level API mocking using MSW (Mock Service Worker), all while maintaining an accessibility-first approach.
