I think it is of at least slight interest to some who missed it, to bring back this thread from 2018, about Oracle code (I too once worked on it so I immediately saved that comment link when it was posted):
Yes it is about tests in general. I think it fits the discussion and many comments very well, this does not really seem to be about only unit tests specifically. Many comments are more general in tone.
The very comment at the top of this sub-thread does not seem to limit itself to the subject of unit tests.
