[SNMP4J] Unit Test SNMP v3 Agent with TestSnmpManager

[ulrich berl]

Hi Frank!

As i use one instance of a TestSnmpManager in my unit test now i use 'Key Localization' AND 'USM Separation' because following series of unit test will fail (WrongDigest):

Unit Test 1 - TEST V3 GET SysDescr for USER 'MD5' WITH WRONG AuthPassPhrase
Unit Test 2 - TEST V3 GET SysDescr for USER 'MD5' WITH CORRECT AuthPassPhrase

or without 'Key Localization' i have to call snmp.getUSM().removeAllUsers(securityName) before adding same use again (snmp.getUSM().addUser)

br, Ulrich
