How do I test asynchronous components in Vue.js using Test Utils?

To test asynchronous components in Vue.js with Test Utils, you can use the await keyword with methods like wrapper.vm.$nextTick() or wrapper.update().

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

Sure! You can mock the API call and then assert the component's behavior after the data is fetched. Use jest.mock() to mock the API.

What about handling promises in my tests?

You can use async/await in your test functions to handle promises. Just make sure to return the promise in your test.

Are there any specific assertions I should use?

Yes, you can use assertions like expect(wrapper.text()).toContain('expected text') to check if the component renders the expected output after the async operation.
