Hi,

I tried with that container version, but I'm still getting the same problem.

Are you sure that your system test is trying to connect with the remote chrome hosted inside the selenium container.

I think your issue is that the tests is trying to run in the local container and gets this error because there is no chrome installed in the build container.

Make sure that is used

 driver_options[:url] = ENV['selenium_remote_url'] if ENV['selenium_remote_url']

My application_system_test_case.rb looks like this:

require "test_helper"
require "socket"

def prepare_options
  driver_options = {
    desired_capabilities: {
      chromeOptions: {
        args: %w[headless disable-gpu disable-dev-shm-usage] # preserve memory & cpu consumption
      }
    }
  }

  driver_options[:url] = ENV["selenium_remote_url"] if ENV["selenium_remote_url"]

  driver_options
end

class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
  driven_by :selenium, using: :chrome, screen_size: [1400, 1400], options: prepare_options
end

And within the configure block ofconfig/environments/test.rb I have:

  net = Socket.ip_address_list.detect{|addr| addr.ipv4_private? }
  ip = net.nil? ? 'localhost' : net.ip_address
  config.domain = ip
  config.action_mailer.default_url_options = { :host => config.domain }

  Capybara.server_port = 8200
  Capybara.server_host = ip
