Any news on the review of this PR ? I'm waiting to use it

I took this branch and it's brand new Jest enabled configuration It works like a charm, I merged into my improved plop generators branch with full examples of Testing AngularJS Components, Directives and Services with Jest:
Improved plop generators, merged with Webpack 4, Webpack Dev server and Jest.
Thank you @fadehelix even if AngularJS is old is the only current tool in which I can do full projects/interviews while learning and gain muscles on new JS Frameworks. I couldn't make this work with karma and ng-inject. I took the Jest approach

Hey @thematho thanks for your kind words :) To be honest I forgot about this PR and I updated branch on my fork because I needed to share somewhere the Jest config :)
I am glad that Jest works not only on my env :)
Your fork looks great! I have to take a closer look over the weekend.
