Validating Input

Before this lesson, we sent five broken booking requests to POST /bookings:

  • {"eventId":7,"seatLabel":""}, an empty seat label.
  • {"eventId":-5,"seatLabel":"A12"}, an event id below zero.
  • {"eventId":7}, no seat label at all.
  • {"eventId":7,"seatLabel":"a12"}, a lowercase row letter.
  • {"eventId":7,"seatLabel":"Z99"}, a seat that Riverside Hall does not have.

All five returned the same answer: 404 Not Found. Each request reached BookingService, which searched for the seat, found nothing, and threw "Seat not found"
