Troubleshooting

You can run unit tests I have prepared like this (install pytest first):

# use your package manager to install the package "pytest"
# here, I examplify with "pip":
$ pip install pytest
$ pytest rr
  ...

  rr/test_analysis.py ....                                                [100%]
