Forum: RSpec Rails3 subdomain constraints with Cucumber and RSpec2

How do I spec rails3 routing constraints?
My Cucumber features pass whatever subdomain I pass in.  Not sure where
or how to spec the subdomain.  Any help would be appreciated.

I have something like the following:

#features/create_account.feature
Scenario:
  Given I visit subdomain "www"
  And I go to the new account page

#accounts_controller_spec.rb
describe AccountsController do
  describe "GET new" do
    before(:each) do
      get :new
    end

    it "should render new.html.haml" do
      response.should render_template(:new)
    end
  end
end

#routes.rb
constraints Promotional do
  resource :account, :only => :new
end

#lib/promotional.rb
class Promotional
    def self.matches?(request)
      request.subdomain.empty? || request.subdomain == "www"
    end
end

There was a commit to rails [1] that got in a day or two before the rc2 
release that lets you pass a full URL to routing assertions. This means 
you can do this in RSpec:

{ :get => "http://www.example.com/accounts/new" }.should 
route_to(:controller => "accounts", :action => "new")

{ :get => "http://foo.example.com/accounts/new" }.should_not be_routable

You need rails-3.0.0.rc2. Not sure what version of rspec-rails you need, 
but you may as well grab rspec-rails-2.0.0.beta.20 (the latest).

I updated to rc2 and RSpec beta.20 but still get an error:

Failure/Error: { :get => "http://foo.example.com/account/new" 
}.should_not be_routable
     expected {:get=>"http://foo.example.com/account/new"} not to be 
routable, but it routes to {:controller=>"accounts", :action=>"new"}

Is this a bug? Any advice?

Many thanks
