To start developing, first create a virtual environment. Inside the virtual environment, install all development dependencies:
pip install -U -r requirements-dev.txt
Alternatively, install tox first. Then, let tox create the virtual environment for you:
pip install -U --user tox
tox -e dev
. .tox/dev/bin/activate # activate the virtual environment
To run lint:
tox -e lint
To run runtime tests:
tox --skip-missing-interpreters
