What are the best practices for testing async code in Vue.js with Jest?

When testing async code in Vue.js with Jest, it's important to use the right methods like async/await and flushPromises.

Can you explain how to use flushPromises in my tests?

Sure! flushPromises is a utility that allows you to wait for all pending promises to resolve. You can use it in your tests to ensure that all async operations are completed before making assertions.

Are there any specific examples of async tests I should look at?

Yes! You can test API calls, component lifecycle methods, and user interactions that trigger async behavior. Would you like a code example?

Yes, please provide a code example for testing an API call.

Here's a simple example: use jest.mock to mock your API call, then test the component's behavior after the async call resolves.
