Several folks have asked me on how to write the unittests and to be honest I've had only minor success with mockito for some basic tests involving a class or two. My java handicap is a further bummer. And it gets customized often for the scenario. For eg: it seems easier to test the contract of the AWSAPI piece than test it using mockito/mockcomponentlocator/junit. Edison emailed about the integration tests and unit tests done for javelin which will be merged to master. I haven't tried it personally but it looks like javelin had good success with it. CloudStack didn't evolve with unittests hand-in-hand and will need some time, I expect, to fall in to that habit. In my (meagre) experience I find it's harder to write unittests around developed code than to write them for a project starting from scratch. > > 4.

I will put in some documentation on how to run them with a simulator. We already run devcloud tests via our CI system at jenkins.a.o. See my response to Marcus for the link.
