RSpec Test of Custom Devise Session Controller Fails with AbstractController::ActionNotFound

Question

I am currently trying to test a custom Devise session controller with rspec. My controller looks like this:

class SessionsController < Devise::SessionsCon         


        

Answer 1

I finally fixed my problem by doing including the devise test helpers, calling the method setup_controller_for_warden in my test AND doing request.env["devise.mapping"] = Devise.mappings[:user]. Like so:

require 'test_helper'

class SessionsControllerTest < ActionController::TestCase
    include Devise::TestHelpers

    test "should reject invalid captcha" do
       setup_controller_for_warden
       request.env["devise.mapping"] = Devise.mappings[:user]

       get :new

       assert_response :success
   end
end

Not sure about your double render problem though, are you sure your supposed to call post :create then render? i'm not sure how rspec is supposed to work.
