title: Use of Selenium for AngularJS based Web Applications
body: <p>I have come to know that Selenium is the father of UI testing. </p>
  
  <p>Now my question is why then Angular team has developed Protractor. Can't the same job (that Protractor does) be done with Selenium for AngularJS based web applications?</p>
  
  <p>Further, people are talking about Nightwatch.js too. So why there are so many E2E testing libraries/frameworks like Protracor or Nightwatch. </p>
