I'm learning to write tests with tox. How do I test only one function with tox? For example if I want to test only test_simple_backup_generation from tests/test_backup_cmd.py of django-backup extension

If you define a parameter {posargs} in your tox.ini you can pass in arguments during execution. In the case of py.test, where

py.test -k test_simple_backup_generation

would only test one function:

[tox]
envlist = py27,py35
[testenv]
deps=pytest
commands=
    pip install -e .[tests,docs]
    py.test {posargs}

and run like

tox -- -k test_simple_backup_generation

  • Thanks for the answer. I have one more question on tox/py.test [here](http://stackoverflow.com/questions/39018056/how-do-the-arguments-are-being-passed-to-test-functions-in-tox-py-test). Can you please check it? – Михаил Павлов Aug 18 '16 at 12:21
