Integrating Unit Testing tool for PMA's Javascript code

[shucon]

We need to add a Unit Testing tool for our Javascript code to avoid bugs in the long run.

I think Jest would be a good tool for us.

And what are the pros and cons vs using mocha ?

I might be wrong, but I think Jest would be better for Vanilla JS as in our case. I'm still looking into both of them.

Please feel free to weigh in.

phpMyAdmin uses a lot of jQuery as well.

I looked at a couple of sites, but most of them have the same information - https://www.testim.io/blog/best-unit-testing-framework-for-javascript/

1. Initial setup of Mocha is more complex.
2. Jest might be more bug prone according to a website. (Source needed)
3. Jest provides parallel testing.
4. Jest has a snapshot capturing feature.
5. Mocha is capable of providing much more flexibility.

Could you open a pull request with some tests using Jest?
