@benpatterson  Please review
I realize this is a loaded topic, but we had discussed including tests as part of coverage when talking about analytics best practices a month or two ago. It can help us stay on top of which tests we're actually using or which ones we're ignoring, etc. I'm pretty sure we track it on edx-platform, too, but could be wrong, here.

Unless you guys would like to discuss, I'd like to  remove the two *test* lines from this file.
