How do I test asynchronous code in React?
To test asynchronous code in React, you can use libraries like Jest and React Testing Library. They provide utilities to handle async operations.
Can you give me an example of testing a component that fetches data?
Sure! You can mock the fetch call and use waitFor to assert the expected outcome after the data is loaded.
What about handling errors in asynchronous tests?
You can simulate an error response and check if your component displays the error message correctly using assertions.
Are there any best practices for testing async code?
Yes, always ensure to clean up after tests, use meaningful test names, and avoid using real API calls in unit tests.
