About mock ZooKeeper
Dear Mr ( or Mrs ) ZooKeeper:
I'm a test engineer of Baidu (China's Google). I'm writing this mail to ask if there is a mock ZooKeeper program that supports stand-alone test. Our development engineers have developed a program with ZooKeeper, but we do not want to use a real ZooKeeper cluster when we test it, a fake ZooKeeper cluster that can run on just a single machine will be more convenient.
By the way, we have downloaded release-3.3.3, but we are not clear about the fuction of release-3.3.3/src/c/tests and release-3.3.3/src/java/test , what can these codes test ?
I'm sorry to my poor English, hope you can understand what I mean :)
Best wishes!

hi,
https://github.com/sgroschupf/zkclient
refer to unit tests in zkclient.
Gateway, InMemoryConnection, ZkServer.. are used to test on single host.
Hope this help,

It can be run on one box. You should read the documentation carefully.

The tests directory you refer to are *internal*
unit/integration/functionality tests. They test if a client correctly
connects to a ZK server for example, if it can create a node in ZK
etc. These tests are only important if you are changing the ZK client
and/or server.
For testing, I suggest you do not use a single ZK instance, because
that would probably not be the same as your production environment.
You can just setup a ZK cluster on a single machine though.
I also suggest you read the manual, because everything is explained
there. To test programs that use ZK, you should understand the
failures of ZK as well as the problems you are trying to solve with ZK
very good. For example network problems, race conditions etc.
