1/ End-to-end tests are supposed to give you confidence. Instead, many Playwright setups create… chaos. Here’s why (and what to do instead) 🧵

3/ Signs your Playwright setup is failing • Flaky tests due to shared state or data interference • Failures on retries because of leftover state • Tests wasting time on repetitive UI setup • Symptoms reappearing unexpectedly

4/ The core problem: too much setup in the UI. If half your suite is just logging in, preparing users, etc., you’re doing it wrong.

5/ The alternative: API-driven test data Create your users, subscriptions, and test state via API instead of the UI. Use fixtures to inject that data into Playwright.

7/ Use shared fixtures. If external dependencies fail (e.g. a third-party API), it should be handled at the fixture level — not in every single test.

8/ Page objects & explicit concurrency control Define structured interactions (buying a product, making an order) in a page object. Use Promise.all to wait for both actions + requests so your test doesn’t break due to timing nuances.

9/ In short: ✅ Start with stable foundations ✅ Invest in API-level setup early ✅ Use fixtures, page objects, and shared abstractions Your test suite should speed you up, not slow you down.
