module ActionSystemTest # :nodoc:
# = Action System Test
#
# System tests let you test real application in the browser. Because system tests
# use a real browser experience you can test all of your JavaScript easily
# from your test suite.
#
# To create an ActionSystemTest in your application, extend your test class
# from <tt>ActionSystemTestCase</tt>. System tests use Capybara as a base and
# allow you to configure the settings through your <tt>system_test_helper.rb</tt>
# file that is generated with a new application or scaffold.
#
# Here is an example system test:
#
# require 'system_test_helper'
#
# class Users::CreateTest < ActionSystemTestCase
# test "adding a new user" do
# visit users_path
# click_on 'New User'
#
# fill_in 'Name', with: 'Arya'
# click_on 'Create User'
#
# assert_text 'Arya'
# end
# end
#
# When generating an application or scaffold a +system_test_helper.rb+ will also
# be generated containing the base class for system testing. This is where you
# can change the driver, add Capybara settings, and other configuration for
# your system tests.
#
# require "test_helper"
#
# class ActionSystemTestCase < ActionSystemTest::Base
# teardown do
# take_failed_screenshot
# Capybara.reset_sessions!
# end
# end
#
# By default, <tt>ActionSystemTest</tt> is driven by the Selenium driver, with
# the Chrome browser, and a browser size of 1400x1400.
#
# Changing the driver configuration options are easy. Let's say you want to use
# and the Firefox browser instead. In your +system_test_helper.rb+
# file add the following:
#
# require "test_helper"
#
# class ActionSystemTestCase < ActionSystemTest::Base
# driven_by :selenium, using: :firefox
#
# teardown do
# take_failed_screenshot
# Capybara.reset_sessions!
# end
# end
#
# +driven_by+ has a required argument for the driver name. The keyword
# arguments are +:using+ for the browser (not applicable for headless drivers),
# and +:screen_size+ to change the size of the screen taking screenshots.
#
# To use a headless driver, like Poltergeist, update your Gemfile to use
# Poltergeist instead of Selenium and then declare the driver name in the
# +system_test_helper.rb+ file. In this case you would leave out the +:using+
# option because the driver is headless.
#
# require "test_helper"
# require "capybara/poltergeist"
#
# class ActionSystemTestCase < ActionSystemTest::Base
# driven_by :poltergeist
#
# teardown do
# take_failed_screenshot
# Capybara.reset_sessions!
# end
# end
#
# Because <tt>ActionSystemTest</tt> is a shim between Capybara and Rails, any
# driver that is supported by Capybara is supported by Action System Test as
# long as you include the required gems and files.
