Thank you for the bug report. We're fixing the issue in #1389. In the very short run, you should be able to run the tests by installing Bean Machine with its test dependencies:

python -m pip install "beanmachine[test]"

A slight improvement:

python -m pip install "beanmachine[test]"
pytest src

If you use plain Jane venv and brew to install Eigen and boost, pytest . will try to run tests for all of the packages installed in your environment.
