test coverage gaps

[kevinsa5]

Test coverage is decent but there are some gaps:

The above summary was generated with coverage with something like:

$ pip install pytest
$ coverage run -m pytest
$ coverage report

You can generate a detailed html report to show exactly what lines are and aren't covered with coverage html. This shows that some of the uncovered lines are things like raising exceptions, which are probably not a big deal to not exercise in the test suite, but some of them are more complex chunks of code that might warrant a new test.
