Encountering a connection error while running a Node.js Selenium test case on Chrome. The specific error message received is: "Error: ECONNREFUSED - Connection refused to 127.0

When attempting to run a test case on a Selenium Node.js server, an error was encountered: Error: ECONNREFUSED connect ECONNREFUSED.

var assert = require('assert'),
    test = require('selenium-webdriver/testing'),
    webdriver = require('selenium-webdriver');
test.describe('Google Search', function () {
    test.it('should work', function (done) {
        this.timeout(100000);
        var driver = new webdriver.Builder().withCapabilities(webdriver.Capabilities.chrome()).build();
        driver.get('http://www.google.com');
        var searchBox = driver.findElement(webdriver.By.name('q'));
        searchBox.sendKeys('simple programmer');
        searchBox.getAttribute('value').then(function (value) {
            assert.equal(value, 'simple programmer');
        });
        driver.quit();
        done();
    });
});

Answer №1

It's unsure if your provided example would function correctly; in order to run the tests locally, one needs to appropriately install and load the suitable selenium drivers.

When attempting to utilize Chrome with the

var driver = new webdriver.Builder().forBrowser('chrome')
syntax, I encountered difficulties as Chrome would launch but failed to execute the tests, resulting in the error you mentioned. On the other hand, using FireFox with
var driver = new webdriver.Builder().forBrowser('firefox').build();
worked flawlessly!

The following code proved to be effective when running locally:


  var assert = require('assert'),
    webdriver = require('selenium-webdriver'),
    By = webdriver.By,
    until = webdriver.until,
    chrome = require('selenium-webdriver/chrome'),
    firefox = require('selenium-webdriver/firefox');

  var path = require('chromedriver').path;
  var driver = chrome.Driver.createSession(new chrome.Options(), new 
  chrome.ServiceBuilder(path).build());

  driver.get('http://mysite/myapp/tests/functional/start.html');
