What are some real-world examples of fetch mocking?

Can you give me some real-world examples of fetch mocking?

Sure! Fetch mocking is often used in testing APIs. For instance, in a React application, you might mock fetch calls to simulate server responses.

How do I implement fetch mocking in my tests?

You can use libraries like Jest or MSW (Mock Service Worker) to mock fetch requests in your tests. Would you like a code example?

Yes, please provide a code example!

Here's a simple example using Jest:

global.fetch = jest.fn(() => Promise.resolve({ json: () => Promise.resolve({ data: 'mocked data' }) }));

This mocks the fetch function to return a resolved promise with mocked data.

What are the benefits of using fetch mocking?

Fetch mocking allows you to test your application without relying on real API calls, making tests faster and more reliable.
