Anyone have any pointers on how to test against ZK outside of the

Right now I am manually running a ZK node for the unit tests to
connect to prior to running my test, but I would rather have something
that ant could reliably
automate starting and stopping for CI.

The way I learned about unit testing is that a unit test should be
"isolated", that is: not need to depend on any external resource - most
notably network resources, such as a database, a web server, or
ZooKeeper. (It's still OK to have a test that tests again a network
resource, but that's really an integration test, not a unit test.)
Consequently, the way I write my code for ZooKeeper is against a more
generic interface that provides operations for open, close, getData, and
setData. When unit testing, I substitute in a "dummy" implementation
that just stores data in memory (i.e., a HashMap); when running live
code I use an implementation that talks to ZooKeeper.
