+1  That's exactly how it should be done.  It's how stress tests are performed.

You can modify the simulator plugin to vary its response to play devil's advocate to test
out different theories.

Also, the simulator today does not have this but you should be able to make it implement the
PluggableService interface to expose commands to allow your test client to adjust responses
on the fly.
