Extend the testing of your package to other python environments. It requires that you install other python interpreters on your computer. By default, each time you regenerate your package it will check among all the ‘intended_versions’ that you registered with the pysetup option the python environments that actually exists on your machine and create a tox.ini file with the relevant options:

(dvlpt)$ pmg add tox
(dvlpt)$ pmg rg

To invoke tox, just use the command line tool:

(dvlpt)$ tox

To produce a result like this one.
