API Integration Test

import { describe, test, expect } from 'vitest';
import request from 'supertest';
import { app } from '../app';

describe('POST /api/users', () => {
  test('creates user and returns 201', async () => {
    const response = await request(app)
      .post('/api/users')
      .send({ email: 'test@example.com', name: 'Test' });

    expect(response.status).toBe(201);
    expect(response.body.id).toBeDefined();
