Cassandra has the same problem and has gone through several iterations
of distributed test systems.  The most recent is here:
https://github.com/riptano/cassandra-dtest  Time will tell if this
attempt is more successful.  The obvious prerequisite for something like
this is a set of scripts that make it easy to set up Kafka clusters of
different topologies for testing.

Another thing they do well is having a solid stress/perf tool
distributed with releases, everyone agrees it gives decent results, easy
to hack if you want to test something slightly different and thus it's
widely used.
