I am working on a Behat setup with Selenium and Chromedriver for running Behat tests for a Drupal 7 setup.

I am getting:

exception ‘WebDriver\Exception\UnknownError’ with message 'Timed out waiting for driver server to start.

Above this error, i am also seeing:

21:46:42.198 INFO [ActiveSessionFactory.apply] - Capabilities are: Capabilities {browser: firefox, browserName: chrome, ignoreZoomSetting: false, name: Behat feature suite, tags: [railsonfire_5e8a4d2e-8ba4-4…, PHP 5.6.34]} 21:46:42.199 INFO [ActiveSessionFactory.lambda$apply$11] - Matched factory org.openqa.selenium.remote.server.ServicedSession$Factory (provider: org.openqa.selenium.chrome.ChromeDriverService) /home/rof/src/bitbucket.org/myorganisation/myproject/chromedriver: 1: /home/rof/src/bitbucket.org/myorganisation/myproject/chromedriver: Syntax error: “(” unexpected 21:47:02.201 ERROR [OsProcess.checkForError] - org.apache.commons.exec.ExecuteException: Process exited with an error: 2 (Exit value: 2)

I am running:

java -Dwebdriver.chrome.driver=./chromedriver -jar selenium-server-standalone-3.10.0.jar 2>&1 &

to start selenium with chromedriver in my pipeline.

I am downloading and unzipping chromedriver like so:

      log_out: 'Uitloggen'

Please ignore the ${project.basedir}, this gets replaced with the phing build target.

Ps: Also note that locally all behat tests run perfectly fine.

All suggestions welcome!

  • Could you please share your behat.yml file. Please recheck that you have correctly configured everything required.

  • Ok. Have you started phantomjs before executing the behat. And I think we need to change the port of wd_host. Can you please try with below steps: 1. Change the port as 8643 instead of 4444 for wd_host 2. Open one PuTTY session and execute phantomjs by using the command phantomjs --ignore-ssl-errors=true 3. Take new PuTTY seesion and Execute behat

  • Ok. I have used phantomJS, chromedriver also suitable (port 9515 by default). Can you please look in to stackoverflow.com/questions/43537347/…. Also

Apparently Codeship, the CI provider that I am using, had a different version of chromedriver that conflicted with my setup. Running chromedriver 2.35 fixed the problem.

Many thanks Aswini K for the effort provided though!


Try with below changes on behat.yml file.

            default_session: goutte
            javascript_session: selenium2
                    ssl.certificate_authority: false
                        CURLOPT_SSL_VERIFYPEER: false
                        CURLOPT_CERTINFO: false
                        CURLOPT_TIMEOUT: 120
              wd_host: "http://localhost:9515/wd/hub"
            blackbox: ~
            api_driver: 'drupal'
