cannot load such file -- capybara/minitest

hope somebody can help me with this. I did search but haven't found any working solution.

I've started writing test for an app. My integration tests run fine, but then I decided that since I'm not that much of TDD driven and since I don't have that much time right now to extensively test all layers of the app that I should use instead of integration tests system tests, because they allow me to test the full flow as if in a browser.

Rails 5.1.2

Gemfile (tried different variations, just capybara, then with combinations of both the other two)

gem 'minitest-rails'
gem 'minitest-rails-capybara'
gem 'capybara'

test_helper.rb

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

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  EMPTY_NEW_USER = {
    email: '',
    first_name: '',
    last_name: '',
    username: '',
    password: ''
  }

  EXISTING_USER = {
    email: '****',
    first_name: 'John',
    last_name: 'Doe',
    username: '',
    password: 'testingpass',
    password_confirmation: 'testingpass'
  }

  # Add more helper methods to be used by all tests here...
end

application_system_test_case.rb

require "test_helper"

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

register_logins.rb

require "application_system_test_case"

class RegisterLoginsTest < ApplicationSystemTestCase

  test 'full login flow' do
    visit root_url
    assert_response :success

    find('.email_link').click


  end
end

error when running

rake test:system

LoadError: cannot load such file -- capybara/minitest
/Users/mnussbaumer/code/dvouch/test/application_system_test_case.rb:3:in `<top (required)>'
/Users/mnussbaumer/code/dvouch/test/system/register_logins_test.rb:1:in `<top (required)>'
Tasks: TOP => test:system
(See full trace by running task with --trace)

The full trace adds this:

LoadError: cannot load such file -- capybara/minitest

/Users/mnussbaumer/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/activesupport-5.1.2/lib/active_support/dependencies.rb:292:in `block in require'
/Users/mnussbaumer/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/activesupport-5.1.2/lib/active_support/dependencies.rb:258:in `load_dependency'

/Users/mnussbaumer/code/dvouch/test/application_system_test_case.rb:3:in `<top (required)>'

and goes on on active_support dependencies.

What I have tried:

Adding one, two and three to test_helper.rb:

require "capybara/rails"
require "minitest/rails"
require "minitest/rails/capybara"

I tried with gems:

group :development, :test do
  gem 'minitest-rails'
  gem 'minitest-capybara'
  gem 'capybara'
end

then with 'minitest-rails-capybara'

Thanks

The file capybara/minitest was added to Capybara in version 2.13.0, which is the minimum version Rails requires for its system tests since Rails 5.1.0. Upgrade to the latest version of Capybara (2.14.4) and there should be no need for the minitest-capybara or minitest-rails gems. You will need to also add the 'selenium-webdriver' gem to your test group.

Additionally the assert_response :success line is't valid in Capybara tests because the HTTP response code from the browser Capybara is using isn't generally available.
