where the application.html.erb is 

<!DOCTYPE html>
<html>
    <head>
        <title>Judgement</title>
        <%= stylesheet_link_tag    "application", :media => "all" %>
        <%= javascript_include_tag "application" %>
        <%= csrf_meta_tags %>
    </head>
    <body>
        <nav>
            <% if user_signed_in? then %>
            <%= link_to "You are #{current_user.email}", edit_user_registration_path %>
            <%= link_to "Exit", destroy_user_session_path, { :method => :delete,
                                                             :confirm => "Are you sure"} %>
            <% else %>
            <%= link_to "Sign In", new_user_session_path %>
            <%= link_to "Register", new_user_registration_path %>
            <% end %>
        </nav>
        <%= yield %>
        <div class="notice">
            <%= notice %>
        </div>
        <div class="alert">
            <%= alert %>
        </div>
    </body>
</html>

So this looks like error because "user_signed_in?" helper. But i can not understand what is the point of error.

I am not very familiar with all Rails magic.

UPD: SOLVED

I was must to add

class ActionController::TestCase
  include Devise::TestHelpers
end

to my test/test_helper.rb

If you're using this for view specs in rspec, you'll want to stub it on view, not helper. 

allow(view).to receive(:user_signed_in?).and_return(true)

I suggest to use this functions : https://gist.github.com/989413. Your tests will be more isolated. In your can, you can just stub like this : helper.stub(:user_signed_in?) {false}. The function user_signed_in? should return true or false as you want.

There is a similare question here : Testing helpers in Rails 3 with Rspec 2 and Devise

Edit for Test::Unit

It think you should redefine a method to mock with Test::Unit. Something like this :

module Devise
  module Controllers
    module Helpers    
      def user_signed_in?
        true #Return false if you want
      end
    end
  end
end
