MhsTesting provides two distinct selenium helpers:
 - SeleniumExampleGroup
 - RailsSeleniumStory
 
In order to use either of these you'll need to perform the three following steps. 
 
First, in RAILS_ROOT/config/environment.rb find this line:
  require File.join(File.dirname(__FILE__), 'boot')
 
and put this line after it:
  require File.join(RAILS_ROOT, %w[vendor plugins mhs_testing lib selenium at_exit])
 
Secondly, make a RAILS_ROOT/config/selenium/ directory and put osx.rb file in there with the below contents:
  Selenium::configure do |config|
    config.browser 'firefox'
    # config.browser 'safari'
    # config.browser 'iexplore'
 
    # config.close_browser_at_exit = true
    config.stop_selenium_server = false
    config.stop_test_server = false
  end
  
And lastly, you will need to tell RSpec to not use transactional fixtures. Put the below in stories/helper.rb. This is currently done putting the below in your stories/helper.rb file:
 
  class ActiveRecordSafetyListener
    include Singleton
    def scenario_started(*args)
      # override this so we don't use transactions
    end
 
    def scenario_succeeded(*args)
      # override this so we don't use transactions
    end
    alias :scenario_pending :scenario_succeeded
    alias :scenario_failed :scenario_succeeded
  end
 
 
SeleniumExampleGroup
====================
The SeleniumExampleGroup give you the ability to write normal RSpec specifications that use Selenium. These should go inside of spec/selenium/. They will automatically be up as Selenium-based specifications.
 
RailsSeleniumStory
====================
The RailsSeleniumStory give you the ability to write higher level integration/user-acceptance-test stories with Selenium. To use these give your story a type of RailsSeleniumStory. A group of helpers have been provided inside of the MhsTesting plugin, just look in the mhs_testing/lib/selenium/helpers/ directory.
 
Be sure to add the following line inside of your stories/helper.rb file:
   Spec::Story::Runner.register_listener RailsSeleniumStoryListener.new
 
In order to run the stories be sure to start the selenium and test servers. This can be done with the below rake command:
  rake spec:selenium:server:start
