ATPS: Angular, Protractor, Travis, SauceLabs

A few days ago I got the combination of Angular + Protractor + TravisCI + SauceLabs working together. There are a few quirks into making this work, but nowhere I found a comprehensive description to jump all the obstacles. Here I’ll describe what I did to get there.
