Protractor 
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor is a Node.js program built on top of WebDriverJS. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
Compatibility
Protractor 5 is compatible with nodejs v6 and newer.
Protractor works with AngularJS versions greater than 1.0.6/1.1.4, and is compatible with Angular applications. Note that for Angular apps, the binding and model locators are not supported. We recommend using by.css.
Getting Started
