What are some tips for async testing with Testing Library?
When testing asynchronous code with Testing Library, consider using waitFor
to wait for elements to appear.
Can you explain how waitFor
works?
waitFor
retries the provided callback until it stops throwing an error or the timeout is reached, making it great for async tests.
Are there any common pitfalls to avoid?
Yes, avoid using setTimeout
in your tests, as it can lead to flaky tests. Instead, rely on the built-in async utilities.
What about testing API calls?
For API calls, mock your requests using libraries like msw
to simulate server responses without hitting the actual API.
