To test a simple project that has some tests, here is an example with a `tox.ini` in the root of the project: ```ini [tox] envlist = py37,py38 [testenv] deps = pytest commands = pytest ``` ```console $ tox [lots of output from what tox does] [lots of output from commands that were run] __________________ summary _________________ py37: commands succeeded py38: commands succeeded congratulations :) ``` tox created two `testenvs` - one based on Python 3.7 and one based on Python 3.8, it installed pytest in them and ran the tests. The report at the end summarizes which `testenvs` have failed and which have succeeded. **Note:** To learn more about what you can do with tox, have a look at [the collection of examples in the documentation](https://tox.readthedocs.io/en/latest/examples.html) or [existing projects using tox](https://github.com/search?l=INI&q=tox.ini+in%3Apath&type=Code). ### How it works tox creates virtual environments for all configured so-called `testenvs`, it then installs the project and other necessary dependencies and runs the configured set of commands. See [system overview](https://tox.readthedocs.io/en/latest/#system-overview) for more details. <a href="https://tox.readthedocs.io/en/latest/#system-overview"> <img src="https://raw.githubusercontent.com/tox-dev/tox/master/docs/img/tox_flow.png" alt="tox flow" width="800px" align="center"> </a> ### tox can be used for ... - creating development environments - running static code analysis and test tools - automating package builds - running tests against the package built by tox - checking that packages install correctly with different Python versions/interpreters - unifying Continuous Integration and command line based testing - building and deploying project documentation - releasing a package to PyPI or any other platform - limit: your imagination ### Documentation Documentation for tox can be found at [Read The Docs](https://tox.readthedocs.org). ### Communication and questions For the fastest and interactive feedback please join our [![Discord](https://img.shields.io/discord/802911963368783933?style=flat-square)](https://discord.gg/edtj86wzBX) server.
