Layering additional requirements on people (whether or not you tell them
that they suck first) generally doesn't work unless you're in a position
of power, and even then they often find a way around your requirements.
So I think it's unlikely to work well.
Why don't you tell your friend to build some simple smoke tests --
using Selenium or twill, for example -- that exercise the deployed
site(s)? Then he can figure out quickly and easily if things are
Another strategy might be for him to set up a simple staging environment
on his own and deploy things there first; that would let him break
something other than the production site. If he automates the
deployment from staging -> production and also automates the test
running, then he'll be just as fast when it all works but he won't
deploy broken stuff.
Both of these strategies duck the systemic problem (developers not
testing) but make it easier for your "friend" to do a good job.
