How do I perform end-to-end testing for async code in Vue.js?

To test async code in Vue.js, you can use tools like Cypress or TestCafe. They allow you to simulate user interactions and wait for asynchronous operations to complete.

Can you give me an example of testing a Vue component that fetches data?

Sure! You can use Cypress to visit your component, trigger the fetch, and then assert that the data is displayed correctly after the async call.

What if the async call fails? How can I test that?

You can mock the API response to simulate a failure. In Cypress, you can use cy.intercept() to return an error response and then check how your component handles it.

Are there any best practices for writing these tests?

Yes! Keep your tests isolated, use meaningful names, and ensure they run quickly. Also, always clean up after tests to avoid side effects.
