routes - Rails 4.0 Engine and nested Routing testing with Rspec 3 -

i have written engine:

module mercatormpay24   class admin::paymentscontroller < ::admin::adminsitecontroller     def check_confirmation       @payment = payment.find(params[:id])     end   end end 

and defined route:

mercatormpay24::engine.routes.draw   namespace :admin     'payments/:id/check_confirmation' => 'payments#check_confirmation',          :as => 'check_confirmation'   end end 

that works fine , can called, responds, ...

now want unit test that:

require 'spec_helper' describe mercatormpay24::admin::paymentscontroller, :type => :controller   describe "get #check_confirmation"     "finds payment"       @payment = create(:payment)       :check_confirmation, id: @payment.id       expect(assigns(:payment)).to eql @payment     end   end end 

but gives me error:

no route matches {:action=>"check_confirmation", :controller=>"mercator_mpay24/admin/payments", :id=>"1"} 

while rake routes | grep check_confirmation gives me:

admin_check_confirmation  /admin/payments/:id/check_confirmation(.:format)  mercator_mpay24/admin/payments#check_confirmation 

i guess, i'm doing wrong namespaces here, have no clue, ....

i missing:

routes { mercatormpay24::engine.routes } 

in controller spec.
