What is Protractor?

  • Protractor is an end-to-end test framework for 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.
  • Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part.


  • Download Node.JS
  • Install jdk and add path to environmental variables
  • npm install protractor -g
  • webdriver-manager update


exports.config = {
    seleniumAddress: 'http://localhost:4444/wd/hub',
    capabilities: {
        'browserName': 'chrome'

    baseUrl: 'http://localhost:4000',
    specs: ['example-spec.js'],
    jasmineNodeOpts: {
        showColors: true

Note: Here you can mention on which port you can run test case in baseUrl and you can specify which test cases you want to run in specs if you feel too many test cases then you can specify format like spec/*.js

Writing test case 

describe('angularjs task list',  function()  {
    //test case
    it('should add a task',  function()  {
        element(by.model('taskText')).sendKeys('write a protractor test');
        var  tasks  =  element.all(by.repeater('task in taskList'));
        expect(tasks.get(2).getText()).toEqual('write a protractor test');


1.Here describe and it syntax is from Jasmine framework, browser is a global created by Protractor, which is used for browser-level commands such as navigation with browser.get.

2.You can add one test suite inside other and one test case inside of other test case. It is based on how you will maintain your code.
