Not sure about this one - seems to be a lot of logging and testing packages there, but that's just because everyone does those things, and many people reach for a library to help them test after coming from other languages which required it. Personally I find the built-in testing absolutely fine with table driven tests, sub-tests, I don't feel the need for things like assertions (that's what if is for !).

The logging is more interesting - perhaps a case there for structured logging in the standard library.
