automated software testing

since it happens several times, that people accidentally broke code, a friend of mine and I talked about the possibility of automated software-testing for the proxmark.

some things are easy to automate: eg. does it compile under $OS, or does it start, does it detect the proxmark, etc...  this may be solved using virtual-box/vmware.

when a card emulation is available even testing of communication is automate-able: two proxmarks connected to one pc: one simulating a card, another one reading it.

any other ideas?
