UI Testing:

• Promo:
  • After starting app, one can create a new reservation in /reservations/new with user_id=1 and date_in=05/21/2018, date_out=05/22/2018
  • Then go to /reservation2_rooms/new and book a room with reservation_id=5, room_id=4
  • Now, you should go to /total_cost/1 and see 3094, as promo was activated for this user
  • Also, you can visit /saved_by_promo/1 and should see 136, which is 20% * 340 (room day price) * 2 (days of reservation)
