## What it is
Nox is a command-line tool for flexible test automation in Python, using a standard Python file (noxfile.py) for configuration instead of ini-style formats. It automates running tests, linting, and other tasks across multiple Python environments and virtualenvs.

## Use cases
- run pytest across multiple python versions
- automate linting and testing in isolated virtualenvs
- tox alternative with python-based config
- define test sessions in a noxfile
- run ci tasks locally before pushing
- test a package against different dependency versions

## When to choose
- you prefer configuring test automation in plain Python over ini files
- you need to test across multiple Python interpreters or virtualenvs
- you want a modern, actively maintained tox alternative
- your team already writes Python and wants flexible session definitions

## When to avoid
- you only need a single-environment test run that a Makefile or shell script covers
- your project already standardizes on tox with existing tox.ini infrastructure
- you need polyglot (non-Python) task automation
