Quick Start
Minimal working example:
// Button.test.tsx
import { render, screen, fireEvent } from '@testing-library/react';
import '@testing-library/jest-dom';
import { Button } from './Button';
describe('Button Component', () => {
it('renders button with text', () => {
render(<Button>Click me</Button>);
expect(screen.getByRole('button')).toHaveTextContent('Click me');
});
it('calls onClick handler when clicked', () => {
const handleClick = jest.fn();
render(<Button onClick={handleClick}>Click</Button>);
fireEvent.click(screen.getByRole('button'));
expect(handleClick).toHaveBeenCalledTimes(1);
});
it('disables button when disabled prop is true', () => {
render(<Button disabled>Click me</Button>);
expect(screen.getByRole('button')).toBeDisabled();
});
it('applies variant styles correctly', () => {
// ... (see reference guides for full implementation)
