Ruby on rails designe在rspec特性测试中的应用

ruby-on-rails testing rspec

Ruby on rails designe在rspec特性测试中的应用,ruby-on-rails,testing,rspec,devise,Ruby On Rails,Testing,Rspec,Devise,我编写了以下rspec特性测试规范： require "rails_helper" RSpec.describe "Team management", type: :feature do user_sign_in describe "User creates a new team" do ... expect(page).to have_link("#{team_name}") end end user\u sign\u in方法在myrails\u h

我编写了以下rspec特性测试规范：

require "rails_helper"

RSpec.describe "Team management", type: :feature do
  user_sign_in

  describe "User creates a new team" do
    ...    
    expect(page).to have_link("#{team_name}")
  end
end

user\u sign\u in
方法在my
rails\u helper.rb
中定义：

ENV['RAILS_ENV'] ||= 'test'
require 'spec_helper'
require File.expand_path('../../config/environment', __FILE__)
require 'rspec/rails'
require 'capybara/rails'

...

module UserSignInHelpers
  def user_sign_in
    before(:each) do
      @request.env['devise.mapping'] = Devise.mappings[:user]

      @current_user = FactoryGirl.create(:user)
      @current_user.confirm

      sign_in :user, @current_user
    end
  end
end

RSpec.configure do |config|
  ...
  # The different available types are documented in the features, such as in
  # https://relishapp.com/rspec/rspec-rails/docs
  config.infer_spec_type_from_file_location!

  config.extend UserSignInHelpers,    type: :controller
  config.extend UserSignInHelpers,    type: :feature
  config.include Devise::TestHelpers, type: :controller
  config.include Devise::TestHelpers, type: :feature
end

user\u sign\u in
方法适用于我的所有控制器规格，但当我运行我的功能规格时，它会失败，原因是：

Team management
  User creates a new team
    example at ./spec/features/user_creates_a_new_team_spec.rb:19 (FAILED - 1)

Failures:

  1) Team management User creates a new team
     Failure/Error: Unable to find matching line from backtrace
     NoMethodError:
       undefined method `env' for nil:NilClass
     # /Users/xxxx/.rvm/gems/ruby-2.2.1/gems/devise-3.5.1/lib/devise/test_helpers.rb:24:in `setup_controller_for_warden'
我不明白为什么这在控制器测试中有效，而在功能测试中无效。在特性测试中，我可以做些什么来实现这一点吗

你尝试做的事情有一个基本问题。（
设计
在
典狱长
之上工作）
典狱长
是 
Rack
中间件，但
RSpec
控制器规格甚至不包括
Rack
， 因为这些类型的规范并不意味着要运行完整的应用程序 堆栈，但只有控制器代码

我有一个简单的支持助手，允许我登录和注销用户：

module Auth
  def create_user!
    @user = User.create(email: 'foo@bar.com', password: '11111111')
  end

  def sign_in_user!
    setup_devise_mapping!
    sign_in @user
  end

  def sign_out_user!
    setup_devise_mapping!
    sign_out @user
  end

  def setup_devise_mapping!
    @request.env["devise.mapping"] = Devise.mappings[:user]
  end

  def login_with_warden!
    login_as(@user, scope: :user)
  end

  def logout_with_warden!
    logout(:user)
  end

  def login_and_logout_with_devise
    sign_in_user!
    yield
    sign_out_user!
  end

  def login_and_logout_with_warden
    Warden.test_mode!
    login_with_warden!
    yield
    logout_with_warden!
    Warden.test_reset!
  end
end
在功能中：

RSpec.describe "Team management", type: :feature do
  describe "User creates a new team" do
     login_and_logout_with_warden do
       # tests goes here
     end
  end
end
在控制器中：

RSpec.describe "Team management", type: :controller do
  describe "User creates a new team" do
    login_and_logout_with_devise do
      # tests goes here
    end
  end
end
您是否将Auth放在spec/support/Auth.rb中？如果是，我如何将其包括在内，以使其可用于我的控制器和身份验证规范？我将
config.extend-Auth，type:：controller
和
config.extend-Auth，type:：feature
添加到
rails\u-helper.rb
。下面是当我尝试使用Auth运行测试时发生的情况：我认为您应该使用
include
而不是
extend
，这是不同的事情
include
和
extend
。如果我想在我的规范中访问@user变量，我应该使用
include
？include用于添加方法（
login\u和带有
