Complete 100% test coverage.

[borgar]

Code coverage measurements report that the coverage is 97%. Let's push this through to a perfect 100%. If only for the bragging rights.

@borgar is there a coverage report that's publicly accessible and continually updated? (In other words, is there, or could there be, a code coverage CI?)

It would probably be a good first issue for new contributors to help complete the missing coverage, and such a tool would be very helpful in that regard.

There is no CI backing this, but I suppose I could set up actions here. Coverage can be gotten to using npm run coverage which runs the tests and emits a coverage report. Here is one for the "next version" branch @ #69:

I am not actually sure that the test coverage is lacking, per-se. Many (or all) of these may be due to unreachable code (such as unused member functions) rather than missing tests.
