Description
# tox [](https://pypi.org/project/tox/) [](https://pypi.org/project/tox/) [](https://pepy.tech/project/tox) [](https://tox.readthedocs.io/en/latest/?badge=latest) [](https://github.com/tox-dev/tox/actions/workflows/check.yaml) `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](https://docs.pytest.org/en/latest/) and [devpi](https://www.devpi.net)). 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](https://tox.wiki/en/latest/tutorial/getting-started.html) for an example and more detailed introduction, or watch [this YouTube video](https://www.youtube.com/watch?v=SFqna5ilqig) that presents the problem space and how tox solves it.
