How can I use Vue 3 Testing Library for advanced testing scenarios?

You can use Vue 3 Testing Library to test components with advanced scenarios like mocking APIs, handling events, and testing state management.

Can you give me an example of mocking an API call in a test?

Sure! You can use jest.mock to mock your API calls. For instance, if you have a function that fetches data, you can mock it like this: jest.mock('path/to/api', () => ({ fetchData: jest.fn(() => Promise.resolve(mockData)) }));.

What about testing user interactions?

For user interactions, you can use the fireEvent method. For example, to test a button click, you can do: fireEvent.click(getByText('Submit')); and then assert the expected outcome.

How do I test components that use Vuex?

You can create a mock store using vuex-mock-store and provide it to your component during testing. This allows you to simulate Vuex state and actions.
