tox-no-internet

Workarounds when running tox with no internet connection.

Why

A few issues arise when running tox with no internet connection:

• virtualenv will reach out to pypi to download the latest version of pip, setuptools, and wheel,
• pip will reach out to pypi to download dependencies,
• if your project or one of its dependency uses the setuptools setup_requires keyword in its setup.py* script, easy_install will be used to fulfill these dependencies and will reach out to pypi as well, (see pip documentation on this topic).

How it works

First, set the TOX_PLUGIN_FIND_LINKS environment variable to the local directoy where your packages are. Then the plugin will do the following for you:

• set the environment variable VIRTUALENV_NO_DOWNLOAD,
• create a pip.conf file for each testenv created with no-index option set and find-links option to point to the local directory you specified in TOX_PLUGIN_FIND_LINKS,
• create a disutils.cfg file for each testenv created by tox to tell easy_install to find packages in the local directory you specified.

Installation

$ pip install tox-no-internet
# just use tox as you usually would
$ tox ...

This tox plugin is inspired by Anthony Sottile's tox-virtualenv-no-download.
