Cucumber tests fail for controller that doesn't inherit from ApplicationController

base_controller.rb

module Admin
  class BaseController < ApplicationController
    
    filter_access_to :index

    def index
    end
    
  end
end

Feature: Patents Administration

  Scenario: Patents index
    Given I am on the admin patents page
    Then I should see "Patents"
    And the title should be "Wavetronix - Patents"

patents_controller.rb

module Admin
  class PatentsController < BaseController
    before_filter :find_patent
  
    def index
      
    end
  
  private

    def find_patent
      @patent = Patent.find(params[:id]) if params[:id]
    end
  end
end

web_steps.rb

Given /^I am on the (.*?) page$/ do |text|
  visit eval("#{text.downcase.gsub(/\s/, '_')}_path(locale: 'en')")
end

Then /^I should see "(.*?)"$/ do |text|
  page.must_have_selector('h1', text: text)
end

Then /^the title should be "(.*?)"$/ do |text|
  page.must_have_selector('title', text: text)
end

Trying to implement this feature using BDD, the first step fails as expected: I need to implement Admin::PatentsController. Because it inherits from Admin::BaseController—which has its own index action and view—Admin::PatentsController inherits that action and view as well. When I override the BaseController implementation by explicitly defining an index action and view for the PatentsController, I can see the change in the browser—that it picks up the new index action and view, but the Cucumber step fails because it appears to still be looking at the BaseController index action and view.

Is there a better way to test this?
