Use Tox for running tests

We should add a Tox configuration (tox.ini) to allow running all tests locally, and use tox-travis in the CI configuration to make the expansion automatic.

Here are a few examples to see how that’s meant to work:

• https://github.com/vshn/concierge-cli
• https://github.com/bittner/pyclean
• https://github.com/mdgart/sentrylogs
• https://github.com/jazzband/django-analytical
• https://github.com/behave/behave-django

Note that this also allows to encapsulate the test requirements into tox.ini (and subsequently can make the test requirements file unnecessary 👍).

I’m wary of depending on external services. Thanks for the suggestion anyway @lockwooddev , it’s appreciated.

Tox is pretty mature. Peter, feel free to go ahead if you wish.

@lockwooddev @1138-4EB You’re both right.

The main reason to prefer a Python technology before getting help with other technology is to both lower the barrier for Python developers and stick to common Python practices.

Using Docker is always a valid choice, nowadays, and it’s good that you point out the possibilities. Thank you!
