* Class ScheduleTest is the companion testing class for class Schedule . It implements the following module test plan:
*
* -
* Phase 1: Unit test the constructor.
*
-
* Phase 2: Unit test the simple access method getCategories.
*
-
* Phase 3: Unit test the constructive methods scheduleAppointment,
* scheduleTask, and scheduleEvent.
*
-
* Phase 4: Unit test the constructive methods scheduleMeeting and
* confirmMeeting.
*
-
* Phase 5: Unit test the changeItem and deleteItem methods.
*
-
* Phase 6: Repeat phases 1 through 5.
*
-
* Phase 7: Stress test by scheduling and deleting 100000 items.
