How to write controller tests when you override devise registration controller?

Question

I wish to override the Devise::RegistrationsController to implement some custom functionalality. To do this, I've created a new RegistrationsController like so:

# /app/controllers/registrations_controller.rb class RegistrationsController < Devise::RegistrationsController   def new     super   end end 

and set up my routes like this:

devise_for :users, :controllers => { :registrations => "registrations" } 

and tried to test it like this:

describe RegistrationsController do   describe "GET 'new'" do     it "should be successful" do       get :new       response.should be_success     end   end end 

but that gives me an error:

 1) RegistrationsController GET 'new' should be successful  Failure/Error: get :new  AbstractController::ActionNotFound:    Could not find devise mapping for path "/users/sign_up".    Maybe you forgot to wrap your route inside the scope block? For example:         devise_scope :user do          match "/some/route" => "some_devise_controller"        end  # ./spec/controllers/registrations_controller_spec.rb:13:in `block (3 levels) in <top (required)>' 

So what am I doing wrong?

Answer 1

The problem is that Devise is unable to map routes from the test back to the original controller. That means that while your app actually works fine if you open it in the browser, your controller tests will still fail.

The solution is to add the devise mapping to the request before each test like so:

before :each do   request.env['devise.mapping'] = Devise.mappings[:user] end
