If you're looking for a minimalist framework that can be learned in 10 minutes or so, I recommend "ospec". For me it was a delight compared with Jest.
I recently tried `bun:test` [1], which aims to become a drop-in replacement for Jest. It is quite good, but there is no way to do test coverage at the moment [2]. I am not sure that it will be fixed soon, as to my knowledge there is no test coverage instrumentation on JSC.
I replaced AVA with a minimal testing lib called Oletus [3]. It was also a delight compared to AVA. I am currently one of the maintainers of Oletus.

“It” always caused weird grammatical problems with test descriptions. You can’t always describe tests that way. Some authors would try and some would ignore “it”.
It does assume familiarity with testing in general (ie, how to design for unit testing, how to write clear tests, etc), but you'll need that to use any testing library effectively, and that skill is orthogonal to the library itself.
If you're looking for resources on that, I recommend: https://github.com/testdouble/contributing-tests/wiki/London...
