How to test Controllers under different namespaces and why this test fails? - ruby-on-rails

Question

Dear fellow Overflowers,
I am using Rails 2.3 and I have created a polymorphic Controller which is accessed by Views belonging to different namespaces. Here is the story and thanks for reading it in advance:
I have these routes:
rake routes | grep appointment
new_patient_appointments GET /patients/:patient_id/appointments/new(.:format) {:controller=>"appointments", :action=>"new"}
edit_patient_appointments GET /patients/:patient_id/appointments/edit(.:format) {:controller=>"appointments", :action=>"edit"}
patient_appointments GET /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"show"}
PUT /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"update"}
DELETE /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"destroy"}
POST /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"create"}
new_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/new(.:format) {:controller=>"admin/appointments", :action=>"new"}
edit_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/edit(.:format){:controller=>"admin/appointments", :action=>"edit"}
admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"show"}
PUT /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"update"}
DELETE /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"destroy"}
POST /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"create"}
...these controllers:
Controllers/Admin/doctors_controller.rb
class Admin::DoctorsController < AuthorisedController
end
Controllers/appointments_controller.rb
class AppointmentsController < ApplicationController
end
Controllers/patients_controller.rb
class PatientsController < ApplicationController
end
...and these tests:
The relevant part in the tests:
test/functional/appointments_conrtroller_test.rb
require 'test_helper'
class AppointmentsControllerTest < ActionController::TestCase
fixtures :patients, :appointments, :doctors, :users
# The following passes:
def setup
login_as :admin
end
test "should show patient appointment" do
get :show, :id => patients(:one).to_param, :appointment_id => appointments(:app_one).id
assert_response :success
end
# The following fails, giving the error after the code block:
test "should show doctor appointment" do
get :show, :id => doctors(:one).to_param, :appointment_id => appointments(:app_one).id
assert_response :success
end
end
Error:
4) Error:
test_should_show_doctor_appointment(AppointmentsControllerTest):
ActionController::RoutingError: No route matches {:controller=>"appointments", :id=>"281110143", :action=>"show", :doctor_id=>2}
test/functional/appointments_controller_test.rb:55:in `test_should_show_doctor_appointment'
the test is under the base namespace, so as a next step, I created a test under Admin.
test/functional/admin/appointments_controller_test.rb
class Admin::AppointmentsControllerTest < ActionController::TestCase
fixtures :patients, :appointments, :doctors, :users
# The following passes:
def setup
login_as :admin
end
test "should show doctor appointment" do
get :show, :id => doctors(:one).to_param, :appointment_id => appointments(:app_one).id
assert_response :success
end
end
...and now I get this error:
1) Error:
test_should_show_doctor_appointment(Admin::AppointmentsControllerTest):
RuntimeError: #controller is nil: make sure you set it in your test's setup method.
test/functional/admin/appointments_controller_test.rb:13:in `test_should_show_doctor_appointment'
At this point, I added #controller = AppointmentsController.new under the setup method, only to get the very familiar:
1) Error:
test_should_show_doctor_appointments(Admin::AppointmentsControllerTest):
ActionController::RoutingError: No route matches {:action=>"show", :controller=>"appointments", :doctor_id=>2, :id=>"281110143"}
test/functional/admin/appointments_controller_test.rb:14:in `test_should_show_doctor_appointments'
It seems like a vicious circle to me.
Thanks anyways...

You should probably be doing this instead:
#controller = Admin::AppointmentsController.new
Otherwise you're referencing the controller inside the main namespace and not the Admin namespace.
