What is your strategy for preventing flaky Playwright style tests?

End-to-end tests can drift into flaky territory over time. What structure and waiting strategy keeps them stable and meaningful.

Use user-facing locators, keep assertions on visible outcomes instead of CSS timing, and let Playwright auto-wait unless you have a real app signal like a network response or saved state to wait on.

I’d add one guardrail: freeze the environment so motion and data stop drifting, then assert the stable visual state instead of racing transitions.

test.beforeEach(async ({ page }) => {
  await page.addStyleTag({ content: `*,*::before,*::after{transition:none!important;animation:none!important}` })
})

I also lock fonts, time, and network noise, because most “visual flakes” are really rendering drift rather than Playwright being weird.
