Part 1: Improving Class SeatTest 1. Change testCreateSeat ) to ensure that all prices are within 50c accuracy (i.e. no more than 50c higher or lower than the expected value) 2. In testBooking) perform the same tests on seat2 that were performed on seat1. Ensure that seat2 has a different seat number and cost from seat1. Make the same changes to testCancelBooking () Check that your code is nicely formatted and well commented. Generate your javadoc to check that it is complete and correct. 3. 4.
