How do I test async components in Vue using Vue Testing Library?

To test async components in Vue with Vue Testing Library, you can use the waitFor utility to handle asynchronous updates.

Can you give me an example of how to use waitFor?

Sure! You can use it like this: await waitFor(() => expect(getByText('Async Component')).toBeInTheDocument()); This waits for the text to appear.

What if the async component fails to load?

In that case, you can use waitFor with a timeout or handle the error state in your component to display an error message.

Are there any best practices for testing async components?

Yes! Always ensure your tests are isolated, use mocks for API calls, and clean up after each test to avoid side effects.
