What are the differences between MSW and Mock Service Worker?

MSW (Mock Service Worker) is a library for mocking API requests in tests. It intercepts network requests and allows you to define responses. It's particularly useful for testing and development without relying on a real backend.

Can you explain how MSW works in a testing environment?

Sure! In a testing environment, MSW sets up a service worker that intercepts network requests made by your application. You can define handlers for different request types, allowing you to simulate various server responses.

What are the benefits of using MSW over traditional mocking methods?

Using MSW allows for more realistic testing since it mimics actual network behavior. It also supports both REST and GraphQL APIs, making it versatile. Additionally, it can be used in both browser and Node.js environments.

Are there any limitations to using MSW?

One limitation is that it requires a service worker, which may not be supported in all environments. Also, it might add complexity to your setup if you're not familiar with service workers.
