How can I mock APIs in my tests using Testing Library?

You can use libraries like msw (Mock Service Worker) to mock APIs in your tests with Testing Library. It allows you to intercept network requests and return mock responses.

Can you show me a simple example of how to set it up?

Sure! First, install msw using npm. Then, create a mock service worker and define your handlers for the API endpoints you want to mock.

What about testing error responses?

You can define a handler for error responses in msw. For example, you can return a 404 status code to simulate a not found error.

Is there a way to reset the handlers between tests?

Yes, you can use server.resetHandlers() in your test setup to reset the handlers before each test.
