Thanks Yash, you're correct. It looks like webtest, six, and coverage all aren't compatible at the moment. I ran into this when setting up a fresh development environment a little bit ago and I've been meaning to chase it down.
For the moment, I do have a working test environment with the following deps in pip freeze. My plan this week is to hard code the versions in the dev-requirements and that should unblock tests. From there, we should look at what's not compatible and help talk with upstreams on those packages to help bring up the brokenness in their current latest versions.
While the main packges for the app are version locked, the development ones have been treated a bit more flexible to help catch changes coming down the pipe sooner. Looks like it fought back :)
