I like this PR.

Why did Travis fail?

I'll try the tests manually sometime this week.

Added blank tests.py to see if that would resolve, but it didn't. The first error I get is the following. Sorry about a lot of text. Does anyone know off the top of their head what's going on? Otherwise, I think we'll have to postpone. Looks random, so probably hard to debug.

Looks like it ran fine on Travis CI. Weird?

@pjdufour this is the error that usually occurs when you run unit tests having geoserver running. Is that the case?
