Hi, I've just raised a PR to exchange unittest2 runner for PyTest in TOX. Reasons why are mainly after making so many changes to the base code and having to fight through unittest2 output reports. https://github.com/apache/libcloud/pull/1041
Improvements would include: The test output is so much easier to read, https://travis-ci.org/apache/libcloud/jobs/225048562 You can do things like py.test --lr to re-run only the test that failed last time py.test -l --full-trace to give entire tracebacks on failed tests The test patterns are better, you can use parameterized tests, fixture loading.
