Protractor : ERROR - Unable to start a WebDriver session

I wrote test cases three months back at that time they worked fine now i want to run those test cases in another system so i did basic setup. When i try to run protractor test case now they are failing with 'Unable to start a WebDriver session'. I have tried so many solutions but they didn't work for me. Here i am attaching my protractor.conf.js file and error details.

protractor.conf.js

'use strict';

exports.config = {

seleniumAddress: 'http://127.0.0.1:4444/wd/hub',

baseUrl: 'http://localhost:' + (process.env.PORT || '3036'),

chromeOnly: true,

// To get the maximimum test screen size
onPrepare: function() {
    browser.driver.manage().window().maximize();
},

// list of files / patterns to load in the browser

Solution

  • I ran webdriver-manager start in one command prompt and protractor in another command prompt then only test cases started running
