describe('OrderService', () => {

    const order = await orderService.create({ items: [{ productId: product.id, qty: 2 }] });
    
    expect(order.status).toBe('pending');
    expect(order.items).toHaveLength(1);
    const updated = await db.product.findUnique({ where: { id: product.id } });
    expect(updated.stock).toBe(8);
  });
