  # By default, any exception happening in your Rails application will bubble up
  # to Cucumber so that your scenario will fail. This is a different from how 
  # your application behaves in the production environment, where an error page will 
  # be rendered instead.
  #
  # Sometimes we want to override this default behaviour and allow Rails to rescue
  # exceptions and display an error page (just like when the app is running in production).
  # Typical scenarios where you want to do this is when you test your error pages.
  # There are two ways to allow Rails to rescue exceptions:
  #
  # 1) Tag your scenario (or feature) with @allow-rescue
  #
  # 2) Set the value below to true. Beware that doing this globally is not
  # recommended as it will mask a lot of errors for you!
  #
  ActionController::Base.allow_rescue = false
  
  # Remove/comment out the lines below if your app doesn't have a database.
  # For some databases (like MongoDB and CouchDB) you may need to use :truncation instead.

  # See the DatabaseCleaner documentation for details. Example:
  #

  #     DatabaseCleaner.strategy = :truncation, {:except => %w[widgets]}
  #   end
  #
