Hi, thanks for your post! It was very useful. However I'm struggling a bit to get the system tests running.

I don't know if I'm missing something, but I'm getting a lot of errors when initializing Chromedriver.

Did you include it in your docker image? Is there any script you're executing on the build phase to install chromedriver and it's dependencies?

Thanks again for a great post

Felipe

Hey Felipe,

I think the error that you are getting is when the system test is trying to connect to the chrome driver in the separated container and failed.

I think this can help you by updating this file application_system_test_case.rb

require "test_helper"
require "socket"


def prepare_options
  driver_options = {
    desired_capabilities: {
      chromeOptions: {
        args: %w[headless disable-gpu disable-dev-shm-usage]
      }
    }
  }

  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

Take attention to the code that fetch the selenium_remote_url from the env variable
