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. For Python versions that do not include venv (namely 3.2 and earlier), this
package does nothing and reverts to tox's default implementation.
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 few effects:
- Builds using the
-Werroroption fail, as the deprecations are raised before the test suite can run. - Users cannot take advantage of newer features of the
sitemodule in their test environments. - Eventually, these deprecations will become exceptions in future versions of Python.
By using the builtin venv module, these issues can be avoided.
tox-venv is compatible with both Python 2 and 3, however it only creates test environments in Python 3.3 and later.
Python 3.3 environments are only partially compatible, as not all options (such as --copies/--symlinks) were
supported. Environments for Python 3.4 and later are fully compatible.
