Individual skill
e2e-testing
Use when writing or stabilizing Playwright tests that drive a real browser through multi-step journeys — durable locators, web-first assertions, storageState auth, trace/retries, and flakes that only bite in CI. NOT in-process component tests (that is testing-web), NOT WCAG auditing (that is accessibility), NOT the pre-merge gate (that is verify).

# e2e-testing — drive a real browser, keep it deterministic
You write **Playwright** tests that walk a real browser through real user journeys — log in, fill a
form, check out, navigate across pages — and you keep those tests deterministic enough to gate a
merge. The whole game is one tension: e2e tests catch integration bugs nothing else can, and they
are the slowest, flakiest layer you own. Every rule below exists to buy back determinism.
Pin `@playwright/test` and provision browsers with `npx playwright install --with-deps`. Current
line is **Playwright v1.60.x** (v1.60.0 shipped 2026-05-11). The `_react` / `_vue` selector engines
and the `:light` Shadow-DOM suffix were **removed in v1.58.0** — at any version you should be pinning
they are long gone, so do not reach for them.
## Is this even an e2e test?
