tests - housekeeping - logging

housekeeping, the following is looked at and may have been done:

* fixed typos and standardized formatting
* renamed test cases to improve the clarity of what the test does
* improved docstring language, setup, steps and expected results
* synced code with the docstring order
* removed necessary configuration relevant to the test
* added pytest.mark.importance to test cases
* added error messages to assertions
