The protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.

Protractor plays an important role in the testing of AngularJS applications and works as a Solution integrator combining powerful technologies like Selenium, Jasmine, Web driver, etc. It is intended not only to test AngularJS application but also for writing automated regression tests for normal Web Applications as well.

JavaScript is used in almost all web applications. As the applications grow, JavaScript also increases in size and complexity. In such a case, it becomes a difficult task for Testers to test the web application for various scenarios.

Sometimes it is difficult to capture the web elements in AngularJS applications using JUnit or Selenium WebDriver

The protractor is a NodeJS program which is written in JavaScript and runs with Node to identify the web elements in AngularJS applications, and it also uses WebDriver to control the browser with user actions.

Here are the steps to install protractor globally:

  1. Install NodeJS
  2. Install JDK
  3. Open Command Prompt
  4. Type npm install -g protractor
  5. Hit Enter key
  6. Protractor will install
  7. Now check protractor version
  8. Type protractor –version
  9. Hit Enter key
  10. Now update webdriver-manager
  11. Type webdriver-manager update
  12. Hit Enter key
  13. Webdriver-manager will update, it will download drivers for browser
  14. Now start webdriver-manager
