E2E Tests for a User Registration Form

Problem/Feature Description

A web app has a user registration page. Write Playwright E2E tests for it.

The app runs on http://localhost:3000 with this page:

• /register -- registration form with fields:
  • Full name (required)
  • Email address (required, must be valid email)
  • Password (required, minimum 8 characters)
  • Confirm password (must match password)
  • "I agree to the terms" checkbox
  • "Create Account" button
• On success, redirects to /welcome with a welcome message
• On failure (e.g., email already exists), shows an error banner

API endpoint:

• POST /api/auth/register -- creates account (returns 201 on success, 409 if email exists, 400 for validation errors)

Output Specification

Produce:

• playwright.config.ts -- Playwright configuration
• e2e/registration.spec.ts -- E2E test file
• package.json -- with @playwright/test dependency listed

You may create additional files for good test organization.
