Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you use a pattern that is repeatable and readable for the type of test you need.
I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a
