Improve test coverage

[jlubken]

DSDK testing has been simplified. After activating a python 3.10 virtual environment, use:

pytest

... to show coverage.

Look for ways to add coverage without adding code perhaps by updating configuration files, or loading additional configuration files in the tests.

Familiarize with pytest.raises, pytest.parametrize, pytest.mark, logger.debug, conftest.py, and running pytest --log-cli-level=debug.

Review the lines not covered and pick the easy coverage first. Avoid brittle tests that break when the implementation changes.

Setup meeting with Jason when ready to work on this one. Go over pytest and brittle tests

Test coverage has been improved to 70%. It's good enough for now, though we will want to come back to this in the future
