​Well ok, then it's not useless. :-)

For pure Python packages I think it's less important and can usually

That implies you would be testing code that you didn't install. That allows
preventable mistakes, like publishing releases on PyPI that don't actually
work, or do not even install at all (because you didn't test that).
`setup.py test` doesn't really allow you to fully test that part, but Tox
does.
