Thanks @MichaHoffmann, this is looking nice!
I'm not sure why CircleCI is on strike again, I often see the run fails for first-time contributors, I'll try to see if we can fix it.

I chose that to be consistent with the other assertions in this test. Its probably best to update all of them. While i'm at it should i also convert them to testutil.Ok form?
