Overview

Closes https://github.com/mochajs/mocha/issues/5202 It seems the only reason this wasn't supported was simply the return value of calling beforeAll, etc, was not the hook itself, unlike the result of calling a function like describe, which does use the suite as the return value. I will look into adding tests and maybe some docs

By the way, a tip: the template has a place to put the Closes #5202. 🙂

I edited it in just now.

oh oops, sorry about that 😅 thanks for editing! hm... maybe the failure is a flakey test here?

[JoshuaKGoldberg]

Looks like it! I re-ran the CI job and it's all passing. Phew 😄
