Ruby on Rails functional test with Devise authentication

Question

I'm searching for a solution for a weird problem. I have a controller, that needs authentication (with the devise gem). I added the Devise TestHelpers but i can't get it working.

require 'test_helper'

class KeysControllerTest < ActionController::TestCase  
   include Devise::TestHelpers  
   fixtures :keys

   def setup
      @user = User.create!(
        :email => '[email protected]',
        :password => 'MyTestingPassword',
        :password_confirmation => 'MyTestingPassword'
      )
      sign_in @user
      @key = keys(:one)
   end

   test "should get index" do
      get :index    
      assert_response :success
      assert_not_nil assigns(:keys)
   end

   test "should get new" do
      get :new
      assert_response :success
   end

   test "should create key" do
      assert_difference('Key.count') do
         post :create, :key => @key.attributes
      end

      assert_redirected_to key_path(assigns(:key))
   end

   test "should destroy key" do
      assert_difference('Key.count', -1) do
         delete :destroy, :id => @key.to_param
      end

      assert_redirected_to keys_path
   end

end

And i get the following output in my "rake test" window:

29) Failure:
test_should_create_key(KeysControllerTest) [/test/functional/keys_controller_test.rb:29]:
"Key.count" didn't change by 1.
<3> expected but was
<2>.

 30) Failure:
test_should_destroy_key(KeysControllerTest) [/test/functional/keys_controller_test.rb:37]:
"Key.count" didn't change by -1.
<1> expected but was
<2>.

 31) Failure:
test_should_get_index(KeysControllerTest) [/test/functional/keys_controller_test.rb:19]:
Expected response to be a <:success>, but was <302>

 32) Failure:
test_should_get_new(KeysControllerTest) [/test/functional/keys_controller_test.rb:25]:
Expected response to be a <:success>, but was <302>

Can someone tell my, why devise doesn't authenticate? I'm using the exact same procedure for an AdminController and it works perfect.

Answer 1

Are you using Devise with confirmable? In this case, create is not enough and you need to confirm the user with @user.confirm!

Second, why do you create the user in the functional test? Declare your users in the fixture like this (confirmed_at if you require confirmation only):

test/fixtures/users.yml:

user1: 
id: 1
email: [email protected]
encrypted_password: abcdef1
password_salt:  efvfvffdv
confirmed_at: <%= Time.now %>

and sign them in in your functional tests with:

sign_in users(:user1)

Edit: I just saw, that in my app the Devise-Testhelpers are declared in test/test-helpers.rb and I don't know if this makes a difference, maybe you want to try:

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

class ActionController::TestCase
  include Devise::TestHelpers
end

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.(yml|csv) for all tests in alphabetical order.
  #
  # Note: You'll currently still have to declare fixtures explicitly in integration tests
  # -- they do not yet inherit this setting
  fixtures :all

  # Add more helper methods to be used by all tests here...
end
