tox-tags

This is a Tox plug-in that allows you to tag test environments and then easily select a subset of test environments when running Tox.

The plug-in and its rule system is heavily inspired by nose-attrib.

Here's an example:

[tox]
envlist =
  py27-win,
  py27,
  py34,

[testenv:py27-win]
tags =
  win

Then, you can easily run only the py27-win environment:

$ tox -t win

You can also run all but the py27-win environment:

$ tox -t '!win'
