Write the event flows, entry conditions, and exit conditions for the exceptional use cases for the AnnounceTournament depicted in Figure 4-25. Use include relationships if necessary to remove redundancy.
What will be an ideal response?
This exercise should result in five or more short use cases describing a condition under which the exception occurs
and a flow of events for handling it. Figure 4-13 is an example for one such exceptions. The student will discover that
exceptional use cases should be used for complex cases, while trivial cases (e.g., name in use, maximum number of
tournaments exceeded) could be either omitted or described within the invoking use case. This should to the
realization that writing use cases is different than writing code, as the counterpart is the user and the client, not the
computer or other developers.
