Protractor is an end-to-end testing library for AngularJS. This video lesson will walk through getting Protractor installed and writing your first test.
It looks very similar to the directory structure generated by phpstorm/webstorm for an Angular project. AKA angular-seed.
Also I agree that the first video was quite confusing - where'd all those files come from. I wish they'd mentioned they used angular-seed (if indeed they did use it) right from the start.
