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

You can use Vue Testing Library to test components in a way that resembles how users interact with them. For advanced scenarios, consider using custom render functions, mocking dependencies, and testing asynchronous behavior.

What are some best practices for mocking API calls in my tests?

Best practices include using libraries like msw (Mock Service Worker) to intercept network requests, or jest.mock to mock specific modules. This allows you to simulate API responses without making actual network calls.

Can you give me an example of testing a component with a form?

Sure! You can render the component, simulate user input using fireEvent, and then assert the expected behavior, like checking if the form submission triggers the correct function.

How do I handle asynchronous tests in Vue Testing Library?

For asynchronous tests, use the waitFor utility to wait for certain conditions to be met, such as elements appearing in the DOM after an API call.
