Improve alarm aggregation test reliability and error handling
- Replace hardcoded alarm ID with DEFAULT_ALARM_ID constant - Replace assert statements with validate_none for better error messages - Add alarm reason text for better test traceability Change-Id: I7a6055b8ef9690bdbe84794f9f3c4c5602cabab2 Signed-off-by: AbhishekJ <abhishek.jaiswal@windriver.com>

IMPORTANT: Dynamic Alarm Scenario Handling
|
||||
==========================================
|
||||
During test execution, alarms can be dynamically added/cleared by system events,
|
||||
making count-based validation unreliable:
|
||||
|
||||
Scenario 1: Background alarm interference
|
||||
- Previous count: 1, Test raises +1, clears -1 (expected: 1)
|
||||
- But background system raises +2 alarms during execution
|
||||
- Final count: 3 (test fails despite correct aggregation behavior)
|
||||
|
||||
Scenario 2: System auto-clearing alarms
|
||||
- Previous count: 2, Test raises +1 (expected: 3)
|
||||
- But 1 existing alarm gets auto-cleared due to timing/system fix
|
||||
- Final count: 2 (test fails despite correct aggregation behavior)
|
||||
|
||||
Solution: Skip count-based validation, focus on alarm ID verification
|
||||
- Always verify specific test alarm ID exists/cleared in alarm list
|
||||
- Log alarm summary for debugging but don't assert on counts
|
||||
- Alarm summary doesn't provide individual alarm IDs, so count validation
|
||||
is inherently unreliable in dynamic environments
