Hey @Souptacular, @zelig! So @winsvega has just authored a section for the documentation on the Tests. See http://www.ethdocs.org/en/latest/ethereum-tests/index.html. It's in as a new top-level section for right now. If you think it would be better elsewhere, please do shout out on where you think it should go, and we can move it.
Maybe under "Contracts and Transactions | Developer Tools"?
