[jetty-dev] Tests for the Mongo session storage implementation?

[Christopher Exell <christopher.exell@xxxxxxxxxxxxx>]

We've encountered a couple issues with the Mongo session storage implementation.

1. We are running into what appears be sessions being loaded as empty when  a browser is no longer stuck to single jetty instance with sticky load balancing.

2. Purging, and Scavenging cause the server to be unable to serve requests during purge/scavenge because of synchronization on the _sessionsIds Set.

I'd like to take a crack at investigating/fixing these issues, but I'm not finding any unit tests for the Mongo session storage implementation. Am I overlooking something, or do they need to be written. If they need to be written what are the jetty project's best practices for adding new tests that are dependent on a particular database?
