[Unattended] Testing new install scripts

I'm working on a number of custom installation scripts for my environment, 
and am having trouble testing them.  I find that testing doesn't work very 
well when doing it outside the context of actually installing via 
Unattended, and doing a full install takes forever, compared to the 
problems with my scripts.  That is, an hour of turnaround time to fix a 
path problem or syntax error really delays my development.

Does anyone have any tips on doing testing more quickly?
