为什么我的 RSpec 没有加载 Devise::Test::ControllerHelpers？

Question

我正在使用 Rails 5 和 Devise 3.5.1。

阅读一本关于 creating/testing 和 API 的好（旧）书，它使用 Devise 身份验证。写在Rails5之前，所以选择不用新的api-only版本。

这是我的测试...

#/spec/controllers/api/v1/users_controller_spec.rb    

require 'rails_helper'

describe Api::V1::UsersController, :type => :controller do
    before(:each) { request.headers['Accept'] = "application/vnd.marketplace.v1" }
    describe "GET #show" do
        before(:each) do
            @user = FactoryGirl.create :user
            get :show, params: {id: @user.id}, format: :json
        end
        it "returns the information about a reporter on a hash" do
            user_response = JSON.parse(response.body, symbolize_names: true)
            expect(user_response[:email]).to eql @user.email
        end
        it { should respond_with 200 }
    end
end

这是一个完全出乎意料的 RSpec 错误

Devise::MissingWarden:
       Devise could not find the `Warden::Proxy` instance on your request environment.
       Make sure that your application is loading Devise and Warden as expected and that the `Warden::Manager` middleware is present in your middleware stack.
       If you are seeing this on one of your tests, ensure that your tests are either executing the Rails middleware stack or that your tests are using the `Devise::Test::ControllerHelpers` module to inject the `request.env['warden']` object for you.

所以我去这里 - http://www.rubydoc.info/gems/devise/Devise/Test/ControllerHelpers

并尝试了这个 -> include Devise::Test::ControllerHelpers

这没有帮助，因为文件 controller_helpers.rb 在我的项目中不存在

我错过了什么？

谢谢

Answer 1

您可以将以下内容添加到您的rails_helper：

RSpec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :controller
end

这将在所有 :controller 规范中包含 Devise::Test::ControllerHelpers 模块。

Answer 2

在spec_helper.rb中添加：

config.include Devise::Test::ControllerHelpers, :type => :controller

Answer 3

迷你测试，Rails 4

这适用于原版 Rails 4 MiniTest

test\controllers\users_controller_test.rb

require 'test_helper'

class UsersControllerTest < ActionController::TestCase
  include Warden::Test::Helpers
  include Devise::Test::ControllerHelpers

  setup do
    # https://github.com/plataformatec/devise/wiki/How-To:-Test-with-Capybara
    # @user = users(:admin)
    # sign_in @user
  end

  teardown do
    Warden.test_reset!
  end

  test "login as admin" do
    @user = users :admin
    sign_in @user
    get :dashboard
    assert_redirected_to admin_dashboard_path
  end

end
