// Testing patterns you'll master
import { render, screen, fireEvent, waitFor } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import { UserProfile } from './UserProfile';
 
describe('UserProfile', () => {
  test('displays user information when data loads successfully', async () => {
    const mockUser = {
      id: 1,
      name: 'John Doe',
      email: 'john@example.com'
    };
 
    // Mock API call
    global.fetch = jest.fn(() =>
      Promise.resolve({
        ok: true,
        json: () => Promise.resolve(mockUser),
      })
    );
 
    render(<UserProfile userId={1} />);
 
    // Check loading state
    expect(screen.getByText('Loading...')).toBeInTheDocument();
 
    // Wait for data to load
    await waitFor(() => {
      expect(screen.getByText('John Doe')).toBeInTheDocument();
      expect(screen.getByText('john@example.com')).toBeInTheDocument();
    });
 
    // Cleanup
    global.fetch.mockRestore();
  });
 
  test('handles user interaction correctly', async () => {
    const user = userEvent.setup();
 
    render(<UserProfile userId={1} />);
 
    const button = screen.getByRole('button', { name: /edit profile/i });
    await user.click(button);
 
    expect(screen.getByText('Edit Mode')).toBeInTheDocument();
  });
});
