Issue with Selenium WebDrive with Docker image and Cucumber.io - ruby

Question

Im trying to follow along with the following tutorial.
https://www.youtube.com/watch?v=cPF3GKkBHHY
I was getting the following error.
sh: 1: /sbin/ip: not found
But I managed to resolve that doing apt update then apt install iproute2 -y.
I am now getting the following error
cucumber
Feature: Search for things on Google and see results.
Scenario: See related words when searching. # features/basic.feature:3
When I search for "puppies" # features/step_defs.rb:1
Selenium::WebDriver::Remote::Driver needs :options to be set (ArgumentError)
./features/step_defs.rb:2:in `"I search for {string}"'
features/basic.feature:4:in `I search for "puppies"'
Then I should see "dog" # features/step_defs.rb:7
The error im looking to resolve is this one.
Selenium::WebDriver::Remote::Driver needs :options to be set (ArgumentError)
this is my .env.rb file.
require 'rspec' #for page.shoud etc
require 'capybara/cucumber'
require 'selenium-webdriver'
require 'pry'
#if you're accessing an internal app behind a firewall, you may not need the proxy. You can unset it like so:
#ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
#get IP of host which has 4444 mapped from other container
docker_ip = %x(/sbin/ip route|awk '/default/ { print $3 }').strip
Capybara.register_driver :remote_chrome do |app|
Capybara::Selenium::Driver.new(app,
:browser => :remote,
:desired_capabilities => :chrome,
:url => "http://#{docker_ip}:4444/wd/hub",
:options => chrome_options)
end
Capybara.configure do |config|
config.run_server = false
config.default_driver = :remote_chrome
config.app_host = 'http://www.google.com' # change this to point to your application
end
Any help with this would be greatly appreciated.
Thanks!

Answer 1

You need to create an instance of Selenium::WebDriver::Chrome::Options and pass it to the options argument. Add this chrome_options = Selenium::WebDriver::Chrome::Options.new in your code like below.
require 'rspec' #for page.shoud etc
require 'capybara/cucumber'
require 'selenium-webdriver'
require 'pry'
#if you're accessing an internal app behind a firewall, you may not need the proxy. You can unset it like so:
#ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
#get IP of host which has 4444 mapped from other container
docker_ip = %x(/sbin/ip route|awk '/default/ { print $3 }').strip
# Add options for the Chrome browser
chrome_options = Selenium::WebDriver::Chrome::Options.new
# Disable notifications
chrome_options.add_argument("--disable-notifications")
Capybara.register_driver :remote_chrome do |app|
Capybara::Selenium::Driver.new(app,
:browser => :remote,
:browser_name => :chrome,
:url => "http://#{docker_ip}:4444/wd/hub",
:options => chrome_options)
end
Capybara.configure do |config|
config.run_server = false
config.default_driver = :remote_chrome
config.app_host = 'http://www.google.com' # change this to point to your application
end

Answer 2

Solution:
Update env.rb file.
Before:
require 'rspec' #for page.shoud etc
require 'capybara/cucumber'
require 'selenium-webdriver'
require 'pry'
#if you're accessing an internal app behind a firewall, you may not need the proxy. You can unset it like so:
#ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
#get IP of host which has 4444 mapped from other container
docker_ip = %x(/sbin/ip route|awk '/default/ { print $3 }').strip
Capybara.register_driver :remote_chrome do |app|
Capybara::Selenium::Driver.new(app,
:browser => :remote,
:desired_capabilities => :chrome,
:url => "http://#{docker_ip}:4444/wd/hub")
end
Capybara.configure do |config|
config.run_server = false
config.default_driver = :remote_chrome
config.app_host = 'http://www.google.com' # change this to point to your application
end
After:
require 'rspec' #for page.shoud etc
require 'capybara/cucumber'
require 'cucumber'
require 'pry'
require "selenium-webdriver"
# Ask capybara to register a driver called 'selenium'
Capybara.register_driver :selenium do |app|
Capybara::Selenium::Driver.new(
app,
#what browser do we want? Must match whatever is in our seleniarm stand-alone image
browser: :firefox,
#where does it live? By passing a URL we tell capybara to use a selenium grid instance (not local)
url: "http://#{ENV['SELENIUM_HOST']}:#{ENV['SELENIUM_PORT']}"
)
end
# make the driver we just registered our default driver
Capybara.default_driver = :selenium
# set the default URL for our tests
Capybara.app_host = "https://www.google.com/"
Update basic.feature
Before:
Feature: Search for things on Google and see results.
Scenario: See related words when searching.
When I search for "puppies"
Then I should see "dog"
Scenario: Don't see unrelated words when searching.
When I search for "dachshund"
Then I should NOT see "fish"
After:
Feature: Search for things on Google and see results.
Background:
Given I accept cookies
Scenario: See related words when searching.
When I search for "puppies"
Then I should see "dog"
Scenario: Don't see unrelated words when searching.
When I search for "dachshund"
Then I should NOT see "fish"
Update step_defs.rb
Before:
When("I search for {string}") do |string|
visit "/"
fill_in "q", with: string
click_on "Google Search", match: :first
end
Then("I should see {string}") do |string|
page.should have_content(string)
end
Then("I should NOT see {string}") do |string|
page.should_not have_content(string)
end
After:
Given('I accept cookies') do
visit "/"
click_on "Accept all"
end
When("I search for {string}") do |string|
visit "/"
fill_in "q", with: string
click_on "Google Search", match: :first
end
Then("I should see {string}") do |string|
page.should have_content(string)
end
Then("I should NOT see {string}") do |string|
page.should_not have_content(string)
end
# a handy debugging step you can use in your scenarios to invoke 'pry' mid-scenario and poke around
When('I debug') do
binding.pry
end
Update Dockerfile
Before:
#start with the base ruby image
FROM ruby
#make sure we have a folder called /app
RUN mkdir /app
#cd into our app folder each time we start up
WORKDIR /app
#copy our Gemfile and Gemfile.lock
COPY Gemfile* /app/
#install the gems
RUN bundle
CMD cucumber
After:
#start with the base ruby image
FROM ruby
#always a good idea to update and have an editor
RUN apt-get update; apt-get install -y vim
#make sure we have a folder called /app
RUN mkdir /app
#cd into our app folder each time we start up
WORKDIR /app
#copy our Gemfile and Gemfile.lock
COPY Gemfile* /app/
