tox is a generic virtualenv management and test command line tool

tox

tox aims to automate and standardize testing in Python. It is part of a larger vision of easing the packaging, testing and release process of Python software (alongside pytest and devpi).

tox is a generic virtual environment management and test command line tool you can use for:

• checking your package builds and installs correctly under different environments (such as different Python implementations, versions or installation dependencies),
• running your tests in each of the environments with the test tool of choice,
• acting as a frontend to continuous integration servers, greatly reducing boilerplate and merging CI and shell-based testing.

Please read our user guide for an example and more detailed introduction, or watch this YouTube video that presents the problem space and how tox solves it.
