E2E Testing Snippet

import { test, expect } from '@playwright/test';

test('user login flow', async ({ page }) => {
  await page.goto('/login');
  await page.fill('[data-testid="username-input"]', 'testuser');
  await page.fill('[data-testid="password-input"]', 'password');
  await page.click('[data-testid="login-button"]');
  await expect(page.locator('.dashboard')).toBeVisible();
});
