Rails 3 + Devise + Rspec - undefined method error in Controller test

I have such spec (spec/controllers/stats_controller_spec.rb) to test my controller:

require 'spec_helper'

describe StatsController do
  render_views

  before(:each){ @user = FactoryGirl.create( :user ) }

  describe "GET 'users_in_system'" do
    describe "for non-signed users" do
      it "should deny access" do
        get :users_in_system, :locale => :en
        #...
      end
    end
  end
end

When i run this spec i get such error:

1) StatsController GET 'users_in_system' for non-signed users should deny access
     Failure/Error: get :users_in_system, :locale => :en
     ActionView::Template::Error:
       undefined method `authenticate' for nil:NilClass
     # ./app/views/layouts/_navbar_template.html.haml:16:in `_app_views_layouts__navbar_template_html_haml__2938837959272005060_70149962955560'
     # ./app/views/layouts/application.html.haml:12:in `_app_views_layouts_application_html_haml__243298846079092947_70149956982200'
     # ./spec/controllers/stats_controller_spec.rb:12:in `block (4 levels) in <top (required)>'

I tried to solve this error by adding this line to (spec/spec_helper.rb):

#...

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  #...
end

Then i started to get such error:

1) StatsController GET 'users_in_system' for non-signed users should deny access
     Failure/Error: Unable to find matching line from backtrace
     NoMethodError:
       undefined method `env' for nil:NilClass

I tried to add that (spec/controllers/stats_controller_spec.rb):

describe StatsController do
  render_views
  include Devise::TestHelpers
  #...
end

But that changed nothing. How can i repair that?

UPD: My stats controller:

class StatsController < ApplicationController
  def users_in_system
    @users = User.all
  end
end

My navbar:

%div{ :class => "navbar navbar-inverse navbar-fixed-top" }
  %div{ :class => "navbar-inner" }
    %a{:class => "btn btn-navbar", "data-toggle" => "collapse", "data-target" => ".nav-collapse"}
      %span{:class=>"icon-bar"}
      %span{:class=>"icon-bar"}
      %span{:class=>"icon-bar"}

    = link_to t(".brand_name"), root_path, { :class => "brand" }
    %div{ :class => "nav-collapse" }
      -# Left navigation.
      %ul{ :class => "nav" }
        %li=link_to "About", about_path

      -# Right navigation.
      %ul{ :class => "nav pull-right" }
        - if user_signed_in?
          %li=link_to t(".settings"), edit_user_registration_path
          %li{ :class => "divider-vertical" }
          %li=link_to t(".logout_link"), destroy_user_session_path, :method => :delete

Your backtrace looks like you're using rspec-rails 2.10.0 which had this issue with setup callbacks order. Try upgrading version of that specific gem to 2.10.1 as it should have it fixed.

You're on the right path with

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  #...
end

so I think you can remove explicit include Devise::TestHelpers from your spec file.
