How do I set up advanced testing with Vue Testing Library?

To set up advanced testing with Vue Testing Library, you need to configure your testing environment properly. Start by installing the necessary packages like @testing-library/vue and jest. Then, create a test setup file to configure global settings.

What specific configurations should I include in the setup file?

In your setup file, you can include global mocks, custom render functions, and any necessary plugins. For example, you might want to mock Vue Router or Vuex if your components depend on them.

Can you give an example of mocking Vue Router?

Sure! You can create a mock router using jest.mock and provide a simple implementation that returns a mocked route object. This allows you to test components that rely on routing without needing the actual router.

What about testing components with asynchronous data?

For testing components with asynchronous data, you can use waitFor or findBy queries from Vue Testing Library. These methods help you wait for elements to appear in the DOM after data is fetched.
