The codebase is very small, but there are still some opportunities to cover some of the functions by unit test. Cover the functions that make sense, making minor modifications to the code if necessary.

It would be great if we could just stick to go stdlib for this

Does this mean not pulling in something that implements convenient assertions (e.g. github.com/stretchr/testify)? or something else?

That seems fine. The unit-tests should be small enough, this shouldn't cause too much issue. Keepin' it simple!
