You will also need an AMQP broker like rabbitmq installed and running to run the local server, or to run tests.

To run a development worker, run

poetry run python vaccine/worker.py

To run autoformatting and linting, run

poetry run black .
poetry run isort .
poetry run mypy .
poetry run flake8

To run the tests, run

poetry run pytest
