Tox

Tox is a modern, extensible, and open-source automation tool for running and managing test environments in Python projects. It helps developers automate testing across different Python versions and environments by creating isolated virtual environments, installing project dependencies, and executing configured test commands. Tox integrates with common Python development workflows and supports configurable test environments, dependency management, packaging checks, and automation, making it useful for maintaining reliable and consistent testing across projects.
