What are the best practices for using MSW in testing?

When using MSW (Mock Service Worker) in testing, it's important to set up realistic request handlers, keep your mocks organized, and ensure they reflect the actual API responses.

Can you give me an example of a realistic request handler?

Sure! A realistic request handler might look like this: rest.get('/api/user', (req, res, ctx) => { return res(ctx.json({ id: 1, name: 'John Doe' })); }); This simulates a user fetching their data.

How do I organize my mocks effectively?

You can organize your mocks by grouping them based on features or endpoints. Create separate files for each feature and import them into your test setup.

What should I avoid when using MSW?

Avoid over-mocking responses that don't reflect real-world scenarios, as this can lead to misleading test results.
