Subject Re: Embedded ZK instance for unit testing
Date Mon, 03 Dec 2012 20:56:39 GMT
Thanks for the references guys.

Turns out... my embedded ZK does actually work... on linux, not mac.  :(

I'm not trying to do that for my production app.   I am trying to do that for unit tests.
  I could try to mock out ZK but I'm concerned that'd be both a lot of typing and wouldn't,
well, test against the real thing.

ZK cluster.
