Undefined метод `visit 'при использовании RSpec и Capybara в рельсах

Я не могу заставить capybara работать с rspec. Это дает мне эту ошибку:

undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x16529f8 @example=nil>

Я знаю, что есть много сообщений об этом, но не решения для меня работают. Большинство из них связаны со спецификациями, не находящимися в /spec/features, в которых находится моя.

Сначала ошибка:

$bundle exec rspec spec
F

Failures:

  1) security signs users in
     Failure/Error: visit "/sessions/new"
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x16529f8 @example=nil>
     # ./spec/features/security_spec.rb:4:in `(root)'

 Finished in 0.006 seconds
 1 example, 1 failure

Failed examples:

rspec ./spec/features/security_spec.rb:3 # security signs users in

Я думаю, важно отметить, что сначала я использовал URL-адрес Helper 'new_sessions_path', и он продолжал давать мне ошибку undefined local variable or method 'new_sessions_path'. Я знаю, что это действительно потому, что:

$ rake routes
logout_sessions GET    /sessions/logout(.:format) sessions#logout
       sessions POST   /sessions(.:format)        sessions#create
   new_sessions GET    /sessions/new(.:format)    sessions#new
      contracts POST   /contracts(.:format)       contracts#create
  new_contracts GET    /contracts/new(.:format)   contracts#new

my_app/спецификация/особенность/security_spec.rb:

describe "security", :type => :feature do
  it "signs users in" do
    visit "/sessions/new"
    fill_in "username", :with => "user"
    fill_in "password", :with => "pass"
    click_button "Sign In"

    page.should have_content('Login Successful')
  end
end

Я попытался определить тест выше как с, так и без :type => :feature. Это не имеет никакого значения. Любые идеи, что я должен попробовать дальше?
