How can I mock APIs in Vue.js testing with the Testing Library?

You can use libraries like msw (Mock Service Worker) to mock APIs in your Vue.js tests. It intercepts network requests and allows you to define 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 API handlers. In your test file, start the worker before your tests run.

What if I want to test error responses?

You can define error handlers in msw just like you define success handlers. For example, you can return a 404 status for a specific endpoint.

Is there a way to reset the handlers between tests?

Yes, you can use server.resetHandlers() in your afterEach block to reset the handlers between tests.
