Migrate away from nose

[fabaff]

nose was not maintained in the last five years. Fedora is dropping that package which means that all packages which depends on nose can no longer be build. I guess that other distributions will follow.

Please consider to migrate to pytest or a unitest framework that is still maintained. Thanks.

I will have to look deeper into this as I still intend to support python 2.7
A quick glance on pytest reveals that it needs python 3.5+

Python 2.x is EOL for quite some time now and was intended to be retired in 2015 ;-)

As far as I remembered was the 4.6 series of pytest the last one that supported Python 2.7.

I see. Thanks.
I will keep that in mind when I go through the options.
