How can I test fetch calls using MSW?
You can use Mock Service Worker (MSW) to intercept fetch calls in your tests. It allows you to mock API responses.
Can you show me a basic example of how to set it up?
Sure! First, install MSW with npm. Then, create a handler for your API endpoint and start the service worker in your test setup.
What if I want to test error responses?
You can define a handler that returns an error response. For example, you can use rest.get
to return a 404 status.
Is it possible to test multiple endpoints?
Yes, you can define multiple handlers for different endpoints in the same setup. Just make sure to import them correctly.
