I've had some issues with Cypress selectors randomly failing to find matching elements, even though they are clearly present. Like if I run the same script 10 times it goes through ~7 times. I wanted to try Playwright for another application to avoid such issues.

And then I was very surprised to get almost the exact same issues with Playwright. Running against a different application with different test cases.

Has anyone else had issues like this with React applications? It's very annoying to not be able to write repeatable tests.

Well, Cypress is going to use playwright for their Webkit integration.

Cypress is more limited compared to Playwright such as multi-domains aren't supported, multiple tabs, or popup windows. For my tests that require that I am using Playwright and for the rest I am currently using Cypress. But I do think the test writing experience is better with Cypress :)

I am considering to move to Playwright for everything now with the new Trace Viewer (https://playwright.dev/docs/debug#playwright-trace-viewer); and contribute to that.

This question does come up quite a lot. One thing the remember is that Cypress is "batteries included" testing framework, where Playwright is essentially just the browser automation part of it.

I know the Playwright team is "moving up the stack" and adding many specific testing features, but it's not at the same level (yet?) as Cypress.
