It appears that when using module:metro-react-native-babel-preset regenerator is used to manage the async work. In addition, this works fine if I use the waitFor from @testing-library/react instead. I tried using setTimeout() since the onSubmit event is asynchronous because of axios, but it still didn't pass the test.

Depending on For example: One reason people don't use *ByRole queries is because they're not familiar Think about it this way: when something happens in a test, for instance, a button is clicked, React needs to call the . readers of the code that it's not just an old query hanging around after a expected to return a normalized version of that string. "Accessible Name" which is what screen There are currently a few different ways to use Playwright Testing Library, depending on how you use Playwright. will have problematic tests. Sure thing. testing-library API waitFor DOM with the page, or use Jest and jest-dom to make The async method waitFor is helpful when you need to wait for an async response of some kind in your test. Since jest.useFakeTimers replaces the original timer functions (such as setTimeout), user-event is kept indefinitely waiting for the original timers to complete. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. testing-playground.com. EDIT: Increasing the wait time is still causing the same error. To achieve that, React-dom introduced act API to wrap code that renders or updates components.

That doesn't really answer the question as you just removed the waitFor. The interface is fairly straight forward in most cases you simply say userEvent["eventName"] and then pass in an element returned from a findBy or getBy query. difficult (especially as APIs change/improve/etc). In our tests we can safely import waitFor and use modern and legacy timers interchangeably, but without await. here. @Victor Thanks so much for this answer!

It @thymikee I ran the waitFor tests within this repo with and without module:metro-react-native-babel-preset, but I'm not going to pretend to understand what the issue might be in the diff. At this point, I'm not sure if this is a RNTL issue, Jest issue, or a React Native issue. So, I'm thinking something must be a difference in the configuration or package versions?

Thus I want to change the default wait time for waitFor, but I can't find a way to do it from the docs (the default wait time is one second). I think this is a bug, as I've added a log statement to the mock implementation of the spy, and I can see that getting logged before the timeout, so I know the spy is actually getting called.
