Codeception: Can not start codeception with chrome 59 in headless mode

[korvinko]

What are you trying to achieve?

I trying start codeception with chrome=59.0.3071.86 in headless mode by providing in args 'headless':

tests/acceptance.suite.yml:
      - WebDriver:
          url: https://crm.test
          browser: chrome
          window_size: maximize
          clear_cookies: false
          capabilities:
              chromeOptions:
                  prefs:
                    download.default_directory: '/var/www/crm/tests/_data/market_documents'
                  args:
                    ['disable-infobars', 'headless', 'disable-gpu']

What do you get instead?

Tests could not start and fall down with error:

It is an issue of chromedriver,
I found that you have to set useAutomationExtension capability to false.

Hello,

Have you success to use codeception with chrome 'headless' ? If yes do you use your suite.yml like that ?

    driver-chrome:
        modules:
            config:
              WebDriver:
                  browser: chrome
                  capabilities:
                    useAutomationExtension : false,
                    args:
                      ['disable-infobars', 'headless', 'disable-gpu']

And do you run selenium server with chrome driver linux ?

java -Dwebdriver.chrome.driver="chromedriver-linux64" -jar selenium-server-standalone-3.4.0.jar

Headless mode works for me with Linux Chrome 59 and chromedriver 2.29/2.30, but only if I disable the webdriver option window_size: maximize.
The capability useAutomationExtension : false doesn't help

[korvinko]

@mirao your solution works. Just deleted window_size: maximize.

Working config:

class_name: AcceptanceTester
modules:
    enabled:
      - Db:
          cleanup: false
          dsn: 'mysql:host=localhost;dbname=crm_test'
          password: 'qweewq'
          populate: false
          user: 'root'
      - WebDriver:
          url: https://crm.test
          browser: chrome
          clear_cookies: false

I try to run test in docker image (https://github.com/SeleniumHQ/docker-selenium) . But I see an error:

[Facebook\WebDriver\Exception\UnknownServerException] unknown error: Chrome failed to start: exited normally (Driver info: chromedriver=2.30.477691 (6ee44a7247c639c0703f291d320bdf05c1531b57),platform=Linux 4.8.0-52-generic x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 60.03 seconds Build info: version: '3.4.0', revision: 'unknown', time: 'unknown' System info: host: 'eb3058ce29ac', ip: '172.17.0.2', os.name: 'Linux', os.arch: 'amd64', os.version: '4.8.0-52-generic', java.version: '1.8.0_131' Driver info: driver.version: ChromeDriver

Without 'args' everything is OK.
My acceptance.suite.yml is:

With remote-debugging-port arg tests just hangs

args:
    ['disable-infobars', 'headless', 'disable-gpu', 'window-size=1920x1080', 'remote-debugging-port=9222']

[janeberets]

@johndoejdg , thank You for your answer. But it does not solve my problem.
In case when I use container, and I add 'remote-debugging-port=9222' to config then nothing changed.
But if I run tests without container, without adding 'remote-debugging-port=9222' - test crashed on step:
$I->amOnUrl('http://test.com/test');
And if I run tests without container, with adding 'remote-debugging-port=9222' - test crashed on step:
'Scenario--'
(on very begining)

Some of us were lucky to run Headless Chrome others didn't. Probably we will see better support in future Chrome versions.
