Node.js WebdriverIO errors

Question

I am trying to run the test script from webdriverIO.

This is the code:

var webdriverio = require('webdriverio');
var options = {
    desiredCapabilities: {
        browserName: 'chrome'
    }
};

webdriverio
    .remote(options)
    .init()
    .url('http://www.google.com')
    .getTitle().then(function(title) {
        console.log('Title was: ' + title);
    })
    .end()
    .catch(function(err) {
        console.log(err);
    });

When i run this, i get errors that i cannot understand. This is what Node tells me:

C:\...\webdriverio-node>node test.js
{ Error: A new session could not be created.
    at end() - C:\...\webdriverio-node\test.js:15:6
  details: undefined,

  seleniumStack:

', java.version: \'1.8.0_171\'\nDriver info: driver.version: unknown' } }

And this is the message i get from selenium-server-standalone:

16:49:43.014 INFO [ActiveSessionFactory.apply] - Capabilities are: Capabilities

extEnabled: true, loggingPrefs: org.openqa.selenium.logging..., requestOrigins:

penqa.selenium.remote.server.ServicedSession$Factory (provider: org.openqa.selen
ium.chrome.ChromeDriverService)

When i change line 4 from the code to:

browserName: 'firefox'

This is the error that Node.js generates:

C:\...\webdriverio-node>node test.js
{ Error: An unknown server-side error occurred while processing the command.
    at end() - C:\...\webdriverio-node\test.js:15:6

I am using selenium-server-standalone-3.11.0.jar

Answer 1

This is because appropriate binary could not be found. Checkout this Setup-Chrome section of webdriver.io

With the latest version of Selenium most of the drivers for the browser come with an external driver that has to be downloaded and setup.

Download the latest version of chromedriver from chromedriver for OS and either place it in the same location as ur test.js or set a PATH in windows. It would be automatically picked up. I only tried it with chrome and was able to execute your code successfully.

Personally I use webdriver-manager to manager binaries

npm install webdriver-manager

webdriver-manager update

webdriver-manager start

This will setup all required binary drivers to connect to browser

Answer 2

I was able to solve the firefox part, just be reinstalling Firefox, as the browser installation was corrupted.

Unfortunately though, i was dissapointed that WebdriverIO spawned the Firefox browser before i get back my result.

I don't know if it's possible to run it in headless mode.
