I've worked on an emulated test rig for a replication system (not RDBMS 
but for LDAP).
We used netem (OSS) for the network emulation and a pile of python and 
shell scripts and
C client test apps.
Testing replication is hard, of course, and you have to roll most of it 
yourself :(

In my experience test frameworks tend to provide less useful 
functionality than one might hope.
Sometimes to the point that they're hardly worth bothering with at all.
