How do I use React Testing Library for my components?

React Testing Library is a great tool for testing React components. You can start by installing it using npm or yarn.

What are some basic functions I should know?

Some basic functions include render, screen, and fireEvent. render is used to render your component, screen helps you query elements, and fireEvent simulates user interactions.

Can you give 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();
});
