running unit tests included with xwiki

Hello, I need some help with running the unit tests included with the xwiki package. What do I have to do in order to run the tests (a) from command line (b) from an IDE (eclipse/IntelliJ) (which configurations I have to change etc)? Also, specifically I will like to know how to run the included XMLRpcTest including how I can start the RPC server for the test. Thanks, Bikash
