I looked closer at it and found that tox complains about not being able to find setup.cfg because setup.cfg doesn't have the lines it's looking for (it would need a [tox] section.)
After looking through the urlwatch repo I found they run pytest on [Travis CI](https://travis-ci.org/github/thp/urlwatch/jobs/717142689), so I changed the template to use pytest. There are [some tests that fail](https://gist.github.com/RunningDroid/8eb97e9c58fbf2f949d4029d47b0fdcd) but they're tests for features that are dependent on software that we don't have packaged (pdftotext & pytesseract.)
