Brandon Williams commented on CASSANDRA-9100:
---------------------------------------------

Unfortunately, this is where singletons begin to bite us.  We can't just spin 
up a bunch of gossipers in a unit test, we have to spin up a bunch of JVMs in a 
dtest :(

> Gossip is inadequately tested

> We found a few unit tests, but nothing that exercises Gossip under 
> challenging conditions. Maybe consider a long test that hooks up some 
> gossipers over a fake network and then do fault injection on that fake 
> network. Uni-directional and bi-directional partitions, delayed delivery, out 
> of order delivery if that is something that they can see in practice. 
> Connects/disconnects.
> Also play with bad clocks.
