tox-venv 0.1.0

Use python3 venvs for python3 tox testenvs

What is tox-venv?

tox-venv is a plugin that uses Python 3’s builtin venv module for creating test environments, instead of creating them with the virtualenv package.

Why use tox-venv?

virtualenv is historically python 2/3 compatible, however to achieve this, it ships some files that are pinned at their python 2.6 version, such as the site module (see: pypa/virtualenv#355). This has a couple of effects:

• Builds using the -Werror option fail, as the deprecations are raised before the test suite can run.

• Users cannot take advantage of newer features of the site module in their test environments.

• Eventually, these deprecations will become exceptions in future versions of python.

Eventually, tox-venv should become obsolete once the corresponding PR is merged (tox-dev/tox#630). At that point, it should be safe to simply remove tox-venv from your test dependencies.
