- the nox session "test-coverage" triggers further nox sessions
that run the test suite for all supported Python versions
- the nox session "_test-coverage-run" runs the test suite for
a particular Python version using the coverage tool
- the nox session "_test-coverage-report" combines the individual
coverage reports
- describe how a local develop environment can be set up
- we use poetry to manage the project
=> add pyproject.toml and poetry.lock files
- add a package for the source code
=> "src" layout structure to ensure that pytest runs the tests
against a packaged version installed in a virtual environment
and not the *.py files in the project directory

- ignore poetry's artifacts in git
