使用 Devise 身份验证进行 Ruby on Rails 功能测试

我正在寻找一个奇怪问题的解决方案。我有一个控制器，需要身份验证（使用 devise gem）。我添加了 Devise TestHelpers 但无法让它工作。

require 'test_helper'

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

   def setup
      @user = User.create!(
        :email => '[email protected] /cdn-cgi/l/email-protection',
        :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

我在“rake test”窗口中得到以下输出：

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>

有人可以告诉我，为什么设计无法验证？我对 AdminController 使用完全相同的过程，并且效果完美。

您是否正在使用带有可确认功能的 Devise？在这种情况下，创建是不够的，您需要使用以下命令来确认用户@user.confirm!

其次，为什么在功能测试中创建用户？在夹具中声明您的用户，如下所示（如果您只需要确认，则为confirmed_at）：

测试/装置/user.yml：

user1: 
id: 1
email: [email protected] /cdn-cgi/l/email-protection
encrypted_password: abcdef1
password_salt:  efvfvffdv
confirmed_at: <%= Time.now %>

并使用以下命令在功能测试中登录它们：

sign_in users(:user1)

编辑：我刚刚看到，在我的应用程序中，Devise-Testhelpers 在 test/test-helpers.rb 中声明，我不知道这是否有影响，也许你想尝试：

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
