It will show code style errors in this cases:

• Model class doesn't have docstring at all
• Model class's docstring doesn't describes model's fields
• Model class's proprieties doesn't have docstrings

• DMD1 - Model class doesn't have docstring at all

First you need to install all needed dependencies for development:

pip install -r development.txt 

To install plugin into your current environment:

pip install .

If you are working with PyCharm, this plugin might be useful pytest-pycharm

To fully check your code with style check run this:

pytest --isort --flake8

To just fo style check run this:

pytest --isort --flake8 -m "isort or flake8"

To test your code against different versions of python run:

tox

Note: they must be installed(you can do it by pyenv)

If want ot specify version of python:

tox -e py35

To run in parallel:

tox --parallel auto
