I am a maintainer of Python packages in openSUSE, and I am on my crusade of eliminating nose1 from our distribution. When I look at its repository on https://github.com/nose-devs/nose, the last release 1.3.7 was on 2 Jun 2015, and even the last commit on the master branch was on 4 Mar 2016.
This patch eliminates dependency on nose. Resulting test suite depends on pytest, which is currently perfectly developed and maintained.
Unfortunately, all is not well, three tests fail on me, and I would appreciate some hints what I do wrong:
