Description

Our DUnit test coverage is significantly lacking for the Tomcat session state module. This story aims to improve test coverage of that module.

Write DUnit tests for the following classes:

DeltaSessionAttributeEventBatch
DeltaSessionDestroyAttributeEvent
DeltaSessionStatistics
DeltaSessionUpdateAttributeEvent
AbstractSessionCache
ClientServerSessionCache
CommitSessionValve
DeltaSession
DeltaSessionFacade
DeltaSessionManager
JvmRouteBinderValve
PeerToPeerSessionCache
SessionExpirationCacheListener
TouchReplicatedRegionEntriesFunction
TouchPartitionedRegionEntriesFunction

Write DUnit tests to exercise all versions of Tomcat with client-server and peer-to-peer topologies, with and without local caching enabled. We also want to exercise rebalance, resource management (thresholds), and commit behavior (CommitSessionValve) related configuration as described in the docs. We should scale these tests and the system level tests to do a more realistic workload. A lot of them add a single entry to the session store with just one or two containers.
