Mocha and Chai?

[nelsonic]

(even though jest is the "official" testing framework...) Mocha and Chai appear to be the default choices in the React/Redux world. should we add a section addressing this?

[iteles]

This would make sense to cover in a section, making the book generally more relevant - there are a LOT of testing tutorials out there that use these.

I just found this
https://github.com/ideaq/learn-mocha
while studying mocha, and it appear as a fork from

https://github.com/dwyl/the-book

So i'm quite confuse, may be there is something on mocha on the-book that i'm missing?
In any case good work , thank you for the-book
