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.
