A pytest plugin to enable format checking with black

Project description


A pytest plugin to enable format checking with black.

This is a fork of the original pytest-black plugin by ShopKeep Inc to provide an up-to-date version of this plugin.


There is a minimum requirement of black 22.1.0 or later.


$ pip install pytest-black-ng


To run pytest with formatting checks provided by black:

$ pytest --black

The plugin will output a diff of suggested formatting changes (if any exist). Changes will not be applied automatically.


You can override default black configuration options by placing a pyproject.toml file in your project directory. See example configuration here.


To run the tests, simply run:

$ pytest
$ flake8

CI takes care of running this against a selecting of Python versions.


Distributed under the terms of the MIT license, pytest-black-ng is free and open source software


If you encounter any problems, please file an issue along with a detailed description.
