[chef] test-kitchen and multiple converges

[Greg Symons < >]

Ohai, Chefs!

I'm trying to set up a test in test-kitchen to verify the idempotency of 
one of my resource providers. Has anybody else come up with a way to 1) 
converge multiple times in a test-kitchen suite and 2) after a second 
converge verify that nothing has changed (or at the very least none of 
the things that potentially could've changed if the recipe wasn't 
idempotent)? I tried testing this in chefspec, but unfortunately it 
looks like I need a real chef run to expose my idempotency bug.

Thanks,

Greg
