Qa Testing Playwright

This is a comprehensive Playwright skill that treats E2E testing as a cost center you need to keep lean. It pushes you toward semantic locators (getByRole first, test IDs as fallback), auto-wait instead of sleeps, and a zero-tolerance stance on flaky tests that pass on retry. The preflight checklist alone will save you from the usual port collision and stale process headaches. What stands out is the opinionated hierarchy: smoke tests on PRs, sharded regression on schedule, and an explicit rule to push coverage down to unit and integration layers. If you're setting up Playwright in CI or debugging flakes that only appear in headless mode, the trace-first debugging workflow and sandbox environment guidance are immediately useful.
