To run pytest with checks provided by Darker:

The plugin will output a diff of suggested formatting changes from Black (if any exist). Changes will _not_ be applied automatically.

Customizing Black and isort behavior

Project-specific default options for Black and isort are read from the project’s pyproject.toml file in the repository root. isort also looks for a few other places for configuration.

For more details, see:


To run the tests against a selection of Python interpreters:

$ tox

To run against a specific interpreter (e.g. Python 3.6):

$ tox -e py36

The tox.ini file in the root of this repository is used to configure the test environment.
