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

You can use Vue Testing Library for advanced scenarios by leveraging custom render functions, mocking modules, and using user-event for simulating user interactions.

Can you give me an example of a custom render function?

Sure! A custom render function can wrap your component with providers or context. For example:

import { render } from '@testing-library/vue';
import MyComponent from './MyComponent.vue';

const customRender = (component, options) => {
  return render(component, { ...options, global: { plugins: [/* your plugins */] } });
};

customRender(MyComponent);

What about mocking API calls in my tests?

You can mock API calls using libraries like Jest. For example:

jest.mock('axios');
import axios from 'axios';

axios.get.mockResolvedValue({ data: { /* mock data */ } });

How do I test user interactions with user-event?

You can use user-event to simulate user interactions like clicks and typing. For example:

import userEvent from '@testing-library/user-event';

userEvent.click(screen.getByText('Submit')); // Simulates a click on the Submit button
