# == CapybaraDriver for System Testing
#
# The <tt>CapybaraDriver</tt> is a shim that sits between Rails and
# Capybara.
#
# The drivers Capybara supports are: +:rack_test+, +:selenium+, +:webkit+,
# and +:poltergeist+.
#
# Rails provides its own defaults for Capybara with the Selenium driver
# through <tt>RailsSeleniumDriver</tt>, but allows users to use Selenium
# directly.
#
# To set your system tests to use one of Capybara's default drivers, add
# the following to yur Rails' configuration test environment:
#
# config.system_testing.driver = :rack_test
#
# The +:rack_test+ driver is a basic test driver that doesn't support
# JavaScript testing and doesn't require a server.
#
# The +:poltergeist+ and +:webkit+ drivers are headless, but require some
# extra environment setup. Because the default server for Rails is Puma, each
# of the Capybara drivers will default to using Puma. Changing the configuration
# to use Webrick is possible by initalizing a new driver object.
#
# The default settings for the <tt>CapybaraDriver</tt> are:
#
# #<ActionSystemTest::DriverAdapters::CapybaraDriver:0x007ff0e992c1d8
# @name=:rack_test,
# @server=:puma,
# @port=28100
# >
#
# The settings for the <tt>CapybaraDriver</tt> can be changed from
# Rails' configuration file.
#
# config.system_testing.driver = ActionSystemTest::DriverAdapters::CapybaraDriver.new(
# name: :webkit,
# server: :webrick
# )
