We're in 2020. I wrote Java before you. Here is my first JUnit.

I kind of lied.  This is my first JUnit *that passes*.
It's a close variation on my first JUnit, which is yesterday's
version of the same.

It took crazy too long to complete mostly because of the whacky
interface the CG GameRunner has to run Java agents.

I couldn't have done it without @dbdr.  Not so much for the
technical aspect of the end result so much as for the moral support
while coming up with all sorts of crazy ways to pass the data around,
and trying or proving them wrong.
