How to guarantee the stability of Playwright-related tests across dynamic UIs?

The modern UI is highly dynamic; components load asynchronously, elements get shifted with respect to user roles, or the DOM altars its contents without a full page reload (think SPA behavior). This UI-nature-flip-flop can intrude flakiness and false negatives in Playwright automation.

This is my attempt at collecting real-world stories in how teams tackle:

  • Dynamic locators: Elements that change their IDs or classes frequently (e.g., auto-generated).

  • Asynchronous UI updates: Content loads or buttons become clickable after the API responds?

  • Page transitions and animations: These may delay visibility or interactivity.

  • State-dependent components: Like dropdowns rendering only after a click or a scroll.

Do you:

  • Rely more on data-test-id attributes?

  • Use waitForSelector(), expect(…).toBeVisible(), or a custom polling/wait utility?

  • Structure your tests around Page Object Model to enhance resilience?

  • Put into practice retry strategies or test retries in CI for occasional flakiness?

  • Log screenshots or traces to get faster at diagnosing these failures?

Would love to hear from the pros in QA about how they have dealt with this in production-grade Playwright suites.
