I only have a handful of Jest unit tests, but they each take nearly 30 seconds nowadays and I don't really know why. Maybe because everything is wrapped in a Formik top level tag? Maybe it somehow pulls in and executes all my code multiple times over? There's probably something silly going on there.

Anyway as just the one developer on this project, I don't see the value in writing unit tests for every one of my components. They just work, I'll leave them alone for a few years until someone else builds a new UI.
