tox-virtualenv-no-download
Disable virtualenv (>=14)'s downloading behaviour when running through tox.
Wait, why?
A few goals for test suites are repeatability and speed. In modern
versions of virtualenv (>=14), virtualenv will reach out to pypi to download
the latest version of pip, setuptools, and wheel even when it has a
perfectly good copy of the wheeled packages on disk.
A few reasons why downloading is problematic:
- Reaching out to the network is slow.
- pypi goes down quite often
- You may work in a situation where installation should not come from public pypi.
- If you don't have a network connection,
virtualenvwill outright fail. - Hurts repeatability as you may suddenly get a new version of
setuptools/pip setuptoolshas been unstable in the past, breaking their latest version and compatibility.
How it works
The downloading behaviour of virtualenv can be disabled either by calling
virtualenv --no-download or by setting the environment variable
VIRTUALENV_NO_DOWNLOAD. This tox plugin sets that environment variable
during the virtualenv creation.
Usage
$ pip install tox-virtualenv-no-download
# just use tox as you usually would
$ tox ...
