Well, there's one other reason. Python delivers a unit testing tool
as part of the standard library. Java doesn't. I suspect that this
subliminal hint has its effects.

I do. Writing tests before code is something that I've thought would
be a good idea for literally decades, but it took both XP and having
the test tool delivered with the language to get me to start.
