setup.py test is going to be deprecated

[graingert]

from pytest-dev/pytest#5534

this project also relies on setuptools options that are now considered 'smells':

    setup_requires=[
        'pytest-runner',
    ],
    tests_require=[
        'pytest',
    ],

[graingert]

It may be worth considering what pytest-runner's place is in a PEP517/PEP518 world

[graingert]

pytest no longer recommends pytest-runner. Is it a good idea to mark it for deprecation here?

[jaraco]

Yes, probably. I think I'd wait to officially deprecate this project until setuptools has officially deprecated the test command, but I'm also open to more information sooner. Would you be willing to draft the change?

[monokrome]

@graingert For those who have found this through pytest-runner, what is the new recommendation? Just running py.test?

[merwok]

Yes, run pytest directly, and/or from tox to get isolation, multiple Python versions, etc.
