Devise Controller Test - ActionController::UrlGenerationError

Question

I'm using OmniAuth through Devise in my Rails app. I'm trying to test that my callback method is being called properly and functions correctly. I am currently receiving an error when running my spec.

The error:

Failure/Error: get user_omniauth_authorize_path(:facebook)
ActionController::UrlGenerationError:
    No route matches {:action=>"/users/auth/facebook", :controller=>"users/omniauth_callbacks"} missing required keys: [:action]

My spec:

#spec/controllers/users/omniauth_callbacks_controller_spec.rb
require 'rails_helper'

RSpec.describe Users::OmniauthCallbacksController, :type => :controller do
  context 'get facebook' do
    before do
      request.env["devise.mapping"] = Devise.mappings[:user] # If using Devise
      request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:facebook]
    end
    it 'should create user, redirect to homepage, and create session' do
      get user_omniauth_authorize_path(:facebook)
      expect(response).to redirect_to(user_omniauth_callback_path)
    end
  end
end

Support file:

#spec/support/omniauth.rb
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new({
                                                              :provider => 'facebook',
                                                              :uid => '123545',
                                                              :email => '[email protected]'
                                                          })

Controller:

#app/controllers/users/omniauth_callbacks_controller.rb
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    @user = User.from_omniauth(request.env['omniauth.auth'])

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => 'Facebook') if is_navigational_format? #todo what is this doing
    else
      session['devise.facebook_data'] = request.env['omniauth.auth']
      redirect_to new_user_registration_url
    end
  end
end

Routes:

devise_for :users, :controllers => { :omniauth_callbacks => 'users/omniauth_callbacks' }

I think the issue is in how it's getting routed. I think action should just be 'facebook' not '/users/auth/facebook', but I don't know the right way to resolve this.

Did you ever solve it? I'm facing the same issue and the spec is right and works in older projects. Maybe happens only with newest versions of devise — Fabio

In case anyone stumbles on this looking for answers like I did. I had this problem when adding a second Omniauth strategy. Turns out the problem was I'd forgotton to include the strategy in my model declaration

eg I was already authorising with google

# app/models/user.rb
devise :rememberable, :trackable, :omniauthable, :omniauth_providers => [:google]

but then wanted to add a second provider (eg facebook). I forgot to add facebook to the list of omniauth providers and so was getting that error when my spec ran. I fixed it by changing to

# app/models/user.rb
devise :rememberable, :trackable, :omniauthable, :omniauth_providers => [:google,:facebook]
