如何使用 RSpec 测试设计会话控制器

Question

我在自己的控制器中覆盖 SessionsController 并尝试使用 RSpec 进行测试。拳头，我设置设计与

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

我的规格：

require 'rails_helper'

需要'authentication_helper'

RSpec.describe Users::SessionsController, type: :controller do 包括 AuthenticationHelper

描述'创建新会话'做

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 结束

我的 SessionsController 只返回 http 401 或 http 200。 当我运行我的规范时，我收到了这个错误：

无方法错误： 未定义的方法authenticate?' for nil:NilClass # /usr/local/bundle/gems/devise-3.5.6/app/controllers/devise_controller.rb:103:inrequire_no_authentication' # ./spec/controllers/users/sessions_controller_spec.rb:16:in block (3 levels) in <top (required)>' # ./spec/rails_helper.rb:45:inblock (3 级) in ' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/generic/base.rb:16:in cleaning' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/base.rb:98:incleaning' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb:86:in block (2 levels) in cleaning' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb:87:incall' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb:87:in cleaning' # ./spec/rails_helper.rb:44:inblock (2 levels) in '

我做错了什么？

Answer 1

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

这是一个请求规范的解决方案，改编自 Devise wiki。我们将简单地使用 Warden 的测试助手——您可能已经为您的 Cucumber 测试加载了它们。

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范中知道的那样：

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，为请求规范加载该模块：

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

完成。您现在可以像这样编写请求规范：

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

您必须删除 warden.authenticate! 调用，而不仅仅是 current_user 方法。

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

对于失败案例：

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 中适用于我。在https://github.com/plataformatec/devise/wiki/How-To:-Stub-authentication-in-controller-specs找到这个

你应该有一个登录助手，例如

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
