An example of an AI chatbot conversation about testing asynchronous code using Testing Library.
How do I test asynchronous code with Testing Library?
You can test asynchronous code in Testing Library by using the findBy queries or waitFor utility.
Can you give me an example of using findBy?
Sure! You can use findByText to wait for an element to appear in the DOM. For example: const element = await screen.findByText(/loading/i);.
What about using waitFor?
waitFor is useful for waiting for a condition to be true. For example: await waitFor(() => expect(screen.getByText(/success/i)).toBeInTheDocument());.
Are there any best practices for testing async code?
Yes! Always ensure your tests are deterministic, avoid using setTimeout, and clean up after each test.
