Add tests

Checklist

• Used a fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Follow-up to #29: adds the tests. While everything is contained in the distributed tarball, they are a little hairy, relying on source files a fair amount, as well as the presence of a fairly large number of dependencies, and require a test skip. But progress nonetheless.

Also, I did all three of the missing test dependencies in one PR, and the queue is a bit backed up to get them made into feedstocks, and this will fail until all of them land, but figured it was worth getting the ball rolling.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Hi! This is the friendly automated conda-forge-webservice.

I tried to re-render for you, but it looks like there was nothing to do.

Yay green!

Having gotten these working, it's not really that important that we get another build out with the bumped build number: this could be shelved until the next version drops.

@conda-forge-admin please rerender

There's at least one spurious fail (path-py vs path.py), so we probably need to script/wrap this.

However, some look real, and should be addressed upstream, or further investigated here...

• subprocess32 is required on py2k pytest-services-feedstock#1
• [wip] Fails pip check... tox-feedstock#50

[bollwyvl]

Hopefully once conda-forge/tox-feedstock#50 is closed (about to), pip check will work here.. aside from the path-py stuff. sigh.
