How to run py.test and linters in `python setup.py test` -

i have project setup.py file. use pytest testing framework , run various linters on code (pep8, pylint, pydocstyle, pyflakes, etc). use tox run these in several python versions, build documentation using sphinx.

i run test suites linters on source code python setup.py test task. if acheive this, use python setup.py test command running tests in tox.ini file.

so questions are:

1. is reasonable / practice these actions python setup.py test? or should use other tool that, writing command directly in tox?
2. how setup.py these actions in test task?

i know py.test has integration instructions setup.py test (here: http://pytest.org/latest/goodpractices.html#integrating-with-setuptools-python-setup-py-test-pytest-runner), i'm looking more "arbitrary cli commands" route, since want run several tools.

1. prefer tox these tasks, because

• it check if deps install (on py-versions)
• it can test code multiple python-versions (virtualenv)

and setup (since you're using tox) don't see benefits of writing python setup.py test instead of exact test-commands tox.ini, because add more complexitiy (new users/contributors have search 2 files (tox.ini , setup.py) tests/tools running instead of 1 (tox.ini).

2.

to use command, project’s tests must wrapped in unittest test suite either function, testcase class or method, or module or package containing testcase classes.
