Feature: bypass rescue

  Use `bypass_rescue` to bypass both Rails' default handling of errors in
  controller actions, and any custom handling declared with a `rescue_from`
  statement.

  This lets you specify details of the exception being raised, regardless of
  how it might be handled upstream.

  Background:
    Given a file named "spec/controllers/gadgets_controller_spec_context.rb" with:
      """ruby
      class AccessDenied < StandardError; end

      class ApplicationController < ActionController::Base
        rescue_from AccessDenied, :with => :access_denied

        private

        def access_denied
          redirect_to "/401.html"
        end
      end
      """
