Few questions:

• I am not really good with Jest, need to add more tests. please suggest new tests and approaches.
• I was referring react-use test cases for useRaf, it uses raf-stub which is written in JS. so couldn't use it in tests as types are not available for it

[Sparkenstein]

any plan to merge this?

Tests don't require raf-stub since Jest provides pretty much all needed functionality, see https://github.com/react-hookz/web/blob/master/src/useRafCallback/tests/dom.ts
