#Rspec :: Core - Rails教程第9章的未定义方法'patch'

Question

我收到以下错误,无法弄清楚如何解决它.Stack Overflow上还有一些其他页面可以解决类似的问题,但这些似乎并不适用,或者至少我不够精明,无法解决这个问题.

当我运行authentication_pages_spec时,问题似乎是使用"patch",导致下面的失败.请注意,我已经尝试用"put"替换"patch"并获得相同的结果.

Failures:

1) Authentication authorization for non-signed-in users in the Users controller submitting to the update action

注意:根据Stack Overflow的讨论和这里引用的博客,我选择将我的spec/requests文件夹更改为spec/features,因为这似乎是Capybara在2.0版之后所要求的.

这是我的Gemfile:源' https : //rubygems.org'ruby'2.0.0'#ruby-gemset = railstutorial_rails_4_0

我修改了我的Guardfile以使用spec/features文件夹而不是spec/requests文件夹:

    require 'active_support/inflector'

guard 'spork',  :cucumber_env => { 'RAILS_ENV' => 'test' },
                :rspec_env    => { 'RAILS_ENV' => 'test' } do

  watch('config/application.rb')
  watch('config/environment.rb')
  watch('config/environments/test.rb')
  watch(%r{^config/initializers/.+\.rb$})
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('spec/spec_helper.rb') { :rspec }
  watch('test/test_helper.rb') { :test_unit }
  watch(%r{features/support/}) { :cucumber }
end

guard 'rspec', all_after_pass: false, cli: '--drb' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml)$})                 { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Capybara features specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml)$})          { |m| "spec/features/#{m[1]}_spec.rb" }

  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }

  # Custom Rails Tutorial specs
  watch(%r{^app/controllers/(.+)_(controller)\.rb$}) do |m|
    ["spec/routing/#{m[1]}_routing_spec.rb",
    "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb",
    "spec/acceptance/#{m[1]}_spec.rb",
    (m[1][/_pages/] ? "spec/features/#{m[1]}_spec.rb" :
                      "spec/features/#{m[1].singularize}_pages_spec.rb")]
  end
  watch(%r{^app/controllers/sessions_controller\.rb$}) do |m|
    "spec/features/authentication_pages_spec.rb"
  end
end

用户控制器:

class UsersController < ApplicationController
    attr_accessor :name, :email
  before_action :signed_in_user, only: [:edit, :update]

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      sign_in @user
        flash[:success] = "Welcome to the Sample App!"
        redirect_to @user
    else
        flash[:error] = "Oops!"
        render 'new'
    end
  end

  def edit
    @user = User.find(params[:id])
  end

  def update
    @user = User.find(params[:id])
    if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      sign_in @user
      redirect_to @user
    else
      render 'edit'
    end
  end

  private

    def user_params
        params.require(:user).permit(:name, 
                        :email, :password, :password_confirmation)
    end

    # Before filters

    def signed_in_user
      redirect_to signin_url, notice: "Please sign in." unless signed_in?
    end
end

Spec helper文件在这里:

require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'


Spork.prefork do
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'

  Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
  ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

  RSpec.configure do |config|

    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    config.use_transactional_fixtures = true

    config.infer_base_class_for_anonymous_controllers = false

    config.order = "random"

    config.include Capybara::DSL

    # Added below myself, troubleshooting an 'undefined method 'patch'' message
    config.include Rails.application.routes.url_helpers   
  end
end

Spork.each_run do
  # This code will be run each time you run your specs.

end

最后,为了更好地衡量,config/routes.rb文件在这里:

SampleApp::Application.routes.draw do
  resources :users
  resources :sessions, only: [:new, :create, :destroy]

  root 'static_pages#home'

  match '/signup',    to: 'users#new',             via: 'get'
  match '/signin',    to: 'sessions#new',          via: 'get'
  match '/signout',   to: 'sessions#destroy',      via: 'delete'
  match '/help',      to: 'static_pages#help',     via: 'get'
  match '/about',     to: 'static_pages#about',    via: 'get'
  match '/contact',   to: 'static_pages#contact',  via: 'get'

有堆栈溢出类似的讨论在这里,但该职位的答案是,从移动到./spec/requests的./spec/features测试-我已经完成了.

这里有另一个相关的讨论,答案是require 'spec_helper'在功能文件的顶部使用...我已经拥有了.

最后一个观察:似乎很多关于这个主题的讨论表明问题是Capybara需要在spec/features文件夹中进行测试才能访问URL帮助程序 - 但我的authentication_pages_spec.rb文件似乎没有问题与'访问'.

欣赏任何见解!Rails 4.0的Rails教程处于测试阶段,一直试图弄清楚这是不是一个bug.

*更新*

在实施彼得的建议后,一切都变成了绿色.以下是authentication_pages_spec文件中的修订代码(部分,只是"授权"部分):

  describe "authorization", type: :request do

    .
    .
    .

    describe "as wrong user" do
      let(:user) { FactoryGirl.create(:user) }
      let(:wrong_user) {FactoryGirl.create(:user, email: "wrong@example.com") }
      before { sign_in user, no_capybara: true }

      describe "visiting Users#edit page" do
        before { visit edit_user_path(wrong_user) }
        it { should_not have_title(full_title('Edit user')) }
      end

      describe "submitting a PATCH request to the Users#update action" do
        before { patch user_path(wrong_user) }
        #  NOTE:  Rails Tutorial uses root_url below not root_path
        specify { expect(response).to redirect_to(root_path) }
      end
    end
  end
end

Answer 1

get,put,patch,等只能用于定义:controller和:request规范,而不是一个:feature规范,该规范你authentication_pages_spec.rb,当你改变了它的位置,测试隐含成了.如果你包括type: :request在你的顶级describe,它应该工作.
