tox-envreport is a plugin for tox to document the setup of used virtual environments.
Collected information are stored in a file called env_report.json inside the .tox folder. For example: MY_PROJECT/.tox/env_report.json.
Documentation: https://tox-envreport.readthedocs.io/en/latest/
pip install tox-envreport
The installation of the plugin is enough to automatically activate it for each tox run.
There is nothing more to do or to configure.
tox-envreport creates one common env_report.json file, which contains all information about all used virtual environments (venv) by tox.
Beside this a venv specific file is generated as well and contains information about the related venv only. You can find this file in the venv-specific tox-folder. E.g: MY_PROJECT/.tox/py27/env_report_py27.json for a venv called py27.
The report file itself contains the venv-name as postfix. E.g.: env_report_py27.json.
