-- Run tests: `tox -e py3` but should also work with just `python -m pytest dandi` if in a venv
-- Tests which require an instance of the archive, would use a fixture to start on using docker-compose.
-- Set env var `DANDI_TESTS_PULL_DOCKER_COMPOSE=""` (to empty value) to avoid `docker compose pull` to speed up repetitive runs
-- Run single test: `tox r -e py3 -- dandi/tests/test_file.py::test_function -v`
