How do I test components in React?

You can use testing libraries like Jest and React Testing Library to test your React components.

Can you give 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();
});

What about testing user interactions?

For user interactions, you can use the fireEvent or userEvent methods from React Testing Library to simulate events.

Is there a way to test asynchronous code?

Yes, you can use async/await in your tests along with waitFor to handle asynchronous operations.
