i dont understand what you mean.  the main loop allows you to process commands 
forever and thus test as many commands as you want.

if you're testing something before the main_loop, then i think it is correct 
that you'd "boot" from scratch, get to the main_loop (and thus pass your 
test), and then call "reset" to exit.  if you want to test something else 
before main_loop, start all over from scratch.
