It works on pytest using any Python 2.7+:

verm at peach# pytest-2.7 --version
This is pytest version 4.5.0, imported from 
/usr/local/lib/python2.7/site-packages/pytest.pyc


verm at peach# pytest --version
This is pytest version 4.5.0, imported from 
/usr/local/lib/python3.7/site-packages/pytest.py


Python 2.x support is not going to go away for a while yet.

No, pytest uses an entirely different methodology.  This gives an OK overview of 
the differences between the two:

It's more suited to our requirements and the ability to do group fixtures is 
fantastic for testing cross platform support among other scenarios.
