# == RailsSeleniumDriver for System Testing
#
# The <tt>RailsSeleniumDriver</tt> uses the Selenium 2.0 webdriver. The
# selenium-webdriver gem is required by this driver.
#
# The <tt>RailsSeleniumDriver</tt> is useful for real browser testing and
# supports Chrome and Firefox.
#
# By default Rails system testing will use Rails' configuration with Capybara
# and the Selenium driver. To explictly set the <tt>RailsSeleniumDriver</tt>
# add the following to your Rails' configuration test environment:
#
# config.system_testing.driver = :rails_selenium_driver
#
# Because this driver supports real browser testing it is required that a
# server is configured.
#
# If no server is specified when the driver is initialized, Puma will be used
# by default. The default settings for the <tt>RailsSeleniumDriver</tt>
# are as follows:
#
# #<SystemTesting::DriverAdapters::RailsSeleniumDriver:0x007ff0e992c1d8
# @browser=:chrome,
# @server=:puma,
# @port=28100,
# @screen_size=[ 1400, 1400 ]
# >
#
# The settings for the <tt>RailsSeleniumDriver</tt> can be changed in the
# Rails configuration file.
#
# config.system_testing.driver = SystemTesting::DriverAdapters::RailsSeleniumDriver.new(
# server: :webrick,
# port: 28100,
# screen_size: [ 800, 800 ]
# )
#
# The default browser is set to Chrome because the current version of
# Firefox does not work with selenium-webdriver. If you want to use Firefox,
# you will need to use Firefox 45.0esr or 47.0 and ensure
# that selenium-webdriver is version 2.53.4. To change the browser from
# +:chrome+ to +:firefox+, initialize the Selenium driver in your Rails'
# test environment:
#
# config.system_testing.driver = SystemTesting::DriverAdapters::RailsSeleniumDriver.new(
# browser: :firefox
# )
