Firefox browser isn't opening

[mlagran1]

Meta -

Image(s): selenium/node-firefox

Docker-Selenium Image Version(s): 3.12.0-boron

Docker Version: 17.12.0-ce

OS: High Sierra

Expected Behavior -

Browser will open and execute test.

Actual Behavior -

Unfortunately, when I execute the scripts, the test hangs on the first scenario for a long time and then returns:

"Could not open connection: Notice: Undefined index".

Also, the grid console returns:

2 requests waiting for a slot to be free.
Capabilities {browser: firefox, browserName: firefox, ignoreZoomSetting: false, name: Behat feature suite, tags: [behat, PHP 7.0.11], version: *}
Capabilities {browser: firefox, browserName: firefox, ignoreZoomSetting: false, name: Behat feature suite, tags: [behat, PHP 7.0.11], version: *}

I'm also using the selenium/node-chrome image and I have no issues with that one.

Here's my docker-compose and behat.yml:

docker-compose

version: "2"

services:
  # Behat
  behat:
    hostname: behat
    image: docksal/behat
    volumes:
      - .:/src
    # Run a built-in web server for access to HTML reports
    ports:
     - 8000:8000
    entrypoint: "php -S 0.0.0.0:8000"
  # Selenium
  firefox:
    image: selenium/node-firefox:3.12.0-boron
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      HUB_HOST: hub

  chrome:
    image: selenium/node-chrome:3.12.0-boron
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      HUB_HOST: hub

  hub:
    image: selenium/hub:3.12.0-boron
    ports:
      - "4444:4444"

behat.yml

extensions:
    Behat\MinkExtension:
      selenium2: ~
      default_session: selenium2
      # Configure browser. Browser must be available on wd_host.
      browser_name: firefox
      selenium2:
        wd_host: http://hub:4444/wd/hub
        capabilities: { "browser": "firefox", "version": "*"}

Hi @mlagran1,

I suppose that the matcher can not find a match for "version": "*", you should avoid it or either specify the exact version of the browser you need.

[mlagran1]

Hey @diemo,l I've tried removing the version, specifying the version and leaving the version as an empty string, but I'm still not having any luck.

I have the same issue when I try IE.

[lmtierney]

Seems to me this is a w3c issue. I doubt the correct capabilities are being sent for w3c implementation since the Behat/Mink does not support this yet minkphp/MinkSelenium2Driver#254

[mlagran1]

@lmtierney Do you have any suggestions as a workaround?

[lmtierney]

There's no workaround that I'm aware of if that is in fact what is causing it not to open. That issue is a year and a half old and Firefox has been running w3c for a long time. They should have been ready for it

[mlagran1]

Wow, that is really unfortunate...Thanks for the help

[mlagran1]

The standalone version: selenium/standalone-firefox actually opens up the browser. It can't click elements unfortunately, but at least it opens up. I wonder what the difference between standalone image and node image is.

[diemol]

Thanks @lmtierney for pointing that out!

@mlagran1 I will close this issue in favour of the one in the minkphp repo, since needs to be solved first to allow you to use the docker-selenium images (and Grid) properly.
