This is a test tool that runs on Mac OS X (maybe later on http://www.GNUstep.org) to test a GTA04 board or device that becomes connected through USB. It is recommended to install the AJZaurusUSB driver as well as it fixes some issues with Ethernet interface addressing when swapping boards.
The test procedure is shown in this video: http://www.youtube.com/user/goldelico#p/a/u/0/gCjM48BqfYo
A test needs approx. 5 minutes.
Test coverage isn't 100% of course since we can't automaticaly test the UMTS radio transmission without antenna.
