Investigate unit testing

[Lingomat]

I would like to elevate the reliability of software updates, to try minimize the introduction of bugs with updates since our audience can't stop software upgrades.

From my understanding, it's almost better to write the unit test first. Perhaps we can just port one component to a unit test to assess the impact on development time.

I have to say, I'm more convinced that functions ought to have standardized annotations describing arguments, results and dependencies. It seems to me this would lend itself to testing anyway and will make the code more accessible to other contributors.
