The difficulty means that, in practice, manual checking will not be done thoroughly, which calls into question the value of the testing. This would be very hard and time consuming to do if we had many hundreds or thousands of tests. Exercise 6.13 The regression test we have done so far still requires manual inspection of the output. A positive test could be to test that appointments longer than one hour have the correct duration after being inserted. test zero and negative values for duration and time. Exercise 6.9 Positive Negative 6.1 X 6.2 X 6.3 X 6.4 X 6.5 X 6.6 X Other negative tests: - test how the application handles a 'null' object as an appointment. For instance, try booking a two-hour appointment at 1700 or one at 0900 when the 1000 time is already booked. makeAppointment only uses the starting time of an appointment to check if the slot is free, and it can therefore overwrite other appointments or exceed the boundary (which results in an exception). Exercise 6.8 Several of the tests will fail. For instance you might have a daily meeting with someone. It would make sense to use the same appointment object if you have a recurring appointment.

The tests are not as legitimate anymore, because we can no longer see the difference between the objects (because there is none) and therefore we can't be sure that the appointments are in the correct time slots. Examples of times to test: 9, 13, 17 Exercise 6.7 Yes, it is possible to use the same appointment object at different times within a single day.

It would be wise to check the boundaries as well as at least one non-boundary value. Download Objects First With Java - Solutions and more Java Programming Exercises in PDF only on Docsity! Exercise 6.6 It should be good enough to check just a few of the possibilities.
