How do I set up React Testing Library in my project?

To set up React Testing Library, first install it using npm or yarn: npm install --save-dev @testing-library/react.

Do I need to install any other dependencies?

Yes, you might also want to install @testing-library/jest-dom for additional matchers and jest if you haven't already.

Can you show me a basic test example?

Sure! Here's a simple test:

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

test('renders learn react link', () => {
  render(<MyComponent />);
  const linkElement = screen.getByText(/learn react/i);
  expect(linkElement).toBeInTheDocument();
});

What are some best practices for writing tests?

Some best practices include keeping tests isolated, using descriptive test names, and testing user interactions.
