Distribute your test suites by STAF(STAX)

STAF is a good Open source "test automation" framework which developed by IBM. I am currently using STAF(STAX) to distribute my test Suites which are organized by TestNG, it is improve your efficiency.

Here is a simple sample how I zip, transfer and execute My Test on 2 machines(please format this XML by yourself, if you need to look at it):

hope it helps! More detail instruction, please go to STAF official website:http://staf.sourceforge.net/
