How can I test my React components using Jest?

You can test your React components using Jest by writing unit tests that check the rendering and behavior of your components.

What are some common methods to test components?

Common methods include snapshot testing, simulating user events, and checking component state and props.

Can you show me an example of a simple test?

Sure! Here's a basic example:

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();
});
