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.
