Rails: Capyabra / Selenium Chrome-Driver Settings

Question

I have my Rails-App set up with Capybara . Tests are working fine but I'm getting this error:

2019-05-03 14:51:58 WARN Selenium [DEPRECATION] Selenium::WebDriver::Chrome#driver_path= is deprecated. Use Selenium::WebDriver::Chrome::Service#driver_path= instead.

Gemfile

group :test do
  # Adds support for Capybara system testing and selenium driver
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  # Easy installation and use of chromedriver to run system tests with Chrome
  gem 'chromedriver-helper'
end

test_helper.rb (with or without the disabled lines makes no difference)

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

require 'capybara/rspec'
require 'rspec/rails'
require 'capybara/rails'

RSpec.configure do |config|
  # Capybara.register_driver :chrome do |app|
  #   Capybara::Selenium::Driver.new app, browser: :chrome,
  #                                  options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless disable-gpu])
  # end
  # Capybara.javascript_driver = :chrome
  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end
  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end
  config.shared_context_metadata_behavior = :apply_to_host_groups
  Kernel.srand config.seed
end

Any ideas?

Answer 1

It is not an error,it is a deprecation warning.

The gem chromedriver-helper is deprecated

NOTICE: This gem is out of support as of 2019-03-31 Please use https://github.com/titusfortner/webdrivers instead. See https://github.com/flavorjones/chromedriver-helper/issues/83 for details.

In you gemfile:

group :test do
     gem 'webdrivers', '~> 3.0'
end

group :development, :test do
    gem 'capybara'
end

I'll suggest you to move capybara in the development and test's group, and also update it, if is possible.

Answer 2

this worked for me. Since the gem is deprecated, I just uninstalled the gem

 gem uninstall chromedriver-helper

then remove it from your gem file and run:

bundle update

after that, add the webdriver gem in-place, and bundle install

gem 'webdrivers', '~> 4.0'

bundle install

the warnings should be gone

Answer 3

I had this concern when working on a Rails 6 application in Ubuntu 20.04 .

The issue is that the chrome-helper gem is deprecated. Its last version was 2.1.1 in March 24, 2019.

Here's how I fixed it :

Simply replace the chrome-helper gem with the webdrivers gem in your Gemfile :

So instead of this:

group :test do
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  gem 'chromedriver-helper'
end

You will have this:

group :test do
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  gem 'webdrivers'
end

Then install the gem using:

bundle install

This will update your Gemfile.lock will the webdrivers gem and remove the chrome-helper gem from it as well.

That's all.

I hope this helps
