             Summary: Increase SNMP Unit Test Coverage
                 Key: AMBARI-19944
                 URL: https://issues.apache.org/jira/browse/AMBARI-19944
             Project: Ambari
          Issue Type: Task
          Components: alerts, test
    Affects Versions: 2.5.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 2.5.0


The current unit tests for SNMP alert notifications do not provide enough of an end-to-end coverage there should be. We should mock SNMP4J classes to ensure that the alert framework is capable of completing an end-to-end dispatch of a trap. This includes:
Instrumenting the SNMP4J dispatcher to intercept the SNMP message and validating the OIDs stored
Instrumenting Ambari alert code so that an AlertNotice is picked up and converted into a delivered SNMP message.
This unit test needs to cover test cases:
4 Verify AMBARI_SNMP trap is working fine when alerts are triggered (Need to confirm whether covered in unit tests)
1 Setup a SNMP trap receiver server on one of the hosts
2 Create AMBARI_SNMP trap notification to use the receiver started in Step 1
3 Trigger an alert to be in CRIT status. E.g STOP MR to trigger HistoryServer Alert
4 Verify the traps are received by the receiver and verify the OID received is correct
