How do I integrate Testing Library with my React app?

To integrate Testing Library with your React app, first install it using npm or yarn. You can run npm install --save-dev @testing-library/react.

What are the basic testing functions I can use?

You can use functions like render, screen, and fireEvent to render components, query elements, and simulate events.

Can you show me an example of a simple test?

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();
});

How do I run the tests after writing them?

You can run your tests by using the command npm test or yarn test, depending on your package manager.
