Being a fan of good testing, I'm always trying to find ways to improve testing on various projects. Travis CI and Coveralls are really nice ways to set up continuous integration for your open-source projects. A couple months ago I finally started hearing grumblings about tox and how everyone was it using for their Python test automation. Every time I'd try to wrap my head around it, something always eluded me, so this week I finally decided to dive in head first and see if I could get to the bottom of it and how it could improve my current integration setup.
