UC2.2
UC2.2: Invalid/Corrupted file loaded.
Actors: See Parent Use Case.
Stakeholders and Interests: See Parent Use Case.
Preconditions: See Parent Use Case.
Success Guarantee (Postconditions):
Network Viewer will detect the file is invalid/corrupted, communicate this to user and not crash.
Main Success Scenario
1. User specifies a file to load, either through use of the network viewer GUI or on the command-line with their invocation of the network viewer.
2. Network Viewer scans file for valid ODIN log file data.
3. When no valid entries are found, Network Viewer alerts user that the file is invalid.
Extensions (Alternative Flows):
NONE
Special Requirements:
See Parent Use Case.
Technology and Data Variation List:
See Parent Use Case.
Frequency of Occurrence:
Should in general be infrequent (average of twice a month?) as network viewer's file dialog can filter files displayed by file suffix (e.g. .ona.gz). This condition could however occur several times in rapid succession as user retries file they expect to work.
Open Issues:
None at this time
