How do I set up Jest for my React project?

To set up Jest for your React project, first install Jest and its dependencies using npm or yarn.

What dependencies do I need to install?

You need to install 'jest', 'babel-jest', and 'react-testing-library' for testing React components.

Can you show me an example of a test?

Sure! Here's a simple test for a React component:

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();
});
