如何使用RSpec测试Devise Sessions Controller

Question

我在自己的控制器中重写了SessionsController，并尝试使用RSpec进行测试。 拳头，我用

@request.env["devise.mapping"] = Devise.mappings[:user]

我的规格：

require 'rails_helper'

需要'authentication_helper'

RSpec.describe Users :: SessionsController，类型：：controller包含AuthenticationHelper

描述“创建新会话”

before(:each) do
  setup_auth
end

let(:user) {FactoryGirl.create(:user, username: 'john', email: 'john@gmail.com', password: 'pwd1234')}

it 'should return 200 with valid username and password' do
  post :create, user: {login: 'john', password: 'pwd1234'}

  expect(response).to have_http_status 200
  expect(controller.current_user.id).to eq(user.id)
end

结束

我的SessionsController只是返回http 401或http200。运行规范时，出现此错误：

我究竟做错了什么？

Answer 1

您知道Devise为控制器规格提供了RSpec测试助手。 但是，在请求规范中，它们将不起作用。

这是根据Devise Wiki改编的针对请求规范的解决方案。 我们将只使用Warden的测试助手-您可能已经将它们加载到Cucumber测试中。

首先，我们定义sign_in和sign_out方法。 它们的行为就像您从控制器规格中了解到的那样：

module DeviseRequestSpecHelpers

include Warden::Test::Helpers

def sign_in(resource_or_scope, resource = nil)
  resource ||= resource_or_scope
  scope = Devise::Mapping.find_scope!(resource_or_scope)
  login_as(resource, scope: scope)
end

def sign_out(resource_or_scope)
  scope = Devise::Mapping.find_scope!(resource_or_scope)
  logout(scope)
end
end

最后，加载该模块以获取请求规范：

RSpec.configure do |config|
    config.include DeviseRequestSpecHelpers, type: :request
end

完成。 您现在可以编写这样的请求规范：

sign_in create(:user, name: 'John Doe')
visit root_path
expect(page).to include('John Doe')

Answer 2

您必须存根warden.authenticate!进行warden.authenticate! 调用，而不仅仅是current_user方法。

对于登录成功测试用例：

before(:each) do
  # assuming `user` is defined and returns a User instance
  allow(request.env['warden']).to receive(:authenticate!).and_return(user)
  allow(controller).to receive(:current_user).and_return(user)
end

对于失败情况：

before(:each) do
  allow(request.env['warden']).to receive(:authenticate!).and_throw(:warden, scope: :user)
  allow(controller).to receive(:current_user).and_return(nil)
end

这在设计4.x中对我有用。 在https://github.com/plataformatec/devise/wiki/How-To:-Stub-authentication-in-controller-specs中找到了

例如，您应该有一个帮助登录的人

module AuthenticationHelpers
     module Controller
        def sign_in(user)
           controller.stub(:current_user).and_return(user)
           controller.stub(:user_id).and_return(user.id)
        end
    end

  module Feature
      def sign_in(user, options={})
          visit "/users/sign_in"
          fill_in "Email", with: user.email
          fill_in "Password", with: options[:password]
          click_button "Log in"
      end
  end
end
