What is Vue Testing Library and how do I use it?

Vue Testing Library is a testing utility for Vue.js applications that encourages good testing practices. It helps you test your components in a way that resembles how users interact with them.

Can you give me an example of a simple test using Vue Testing Library?

Sure! Here's a basic example:

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

test('renders a message', () => {
  render(MyComponent);
  const message = screen.getByText(/hello world/i);
  expect(message).toBeInTheDocument();
});

What are some best practices for testing with Vue Testing Library?

Some best practices include:

1. Focus on testing user interactions rather than implementation details.
2. Use queries that resemble how users find elements (like getByText).
3. Keep tests isolated and avoid dependencies on external state.

Where can I find more detailed documentation?
