Distributed JUnit Overview

Ability to distribute JUnit tests allows you to get test results from your build server 2, 3, or 5 times faster depending on amount of nodes you allocate to run your tests. You can also run your distributed JUnits directly from IDE and all IDE native JUnit integration semantics will be preserved.

Distributed Junit support is added starting GridGain 1.6.0 release. In a nutshell it simply takes your regular JUnit TestSuite and runs it in parallel on remote nodes. Even if you don't have remote nodes, the tests within your TestSuite will run in parallel on local node. Both, individual tests and test suites are supported. If you have nested test suites inside of your distributed test suite, then the whole suite will executed in parallel on remote node (note, that tests within a nested suite will still execute sequentially).
