我收到以下错误，不知道如何修复它。Stack Overflow 上还有一些其他页面解决了类似的问题，但这些似乎并不适用，或者至少我不够精明，无法解决。
当我运行 authentication_pages_spec 时，问题似乎与使用“补丁”有关，导致以下失败。请注意，我已经尝试用“put”替换“patch”并得到相同的结果。
Failures:
1) Authentication authorization for non-signed-in users in the Users controller submitting to the update action

注意：根据此处关于Stack Overflow 的讨论以及此处引用的博客，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 版之后所需要的。
这是我的 Gemfile：source ' 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{^spec/support/(.+)\.rb$}) { "spec" }
watch('config/routes.rb') { "spec/routing" }
watch('app/controllers/application_controller.rb') { "spec/controllers" }

watch(%r{^app/controllers/(.+)_(controller)\.rb$}) do |m|

end
watch(%r{^app/controllers/sessions_controller\.rb$}) do |m|

end
用户控制器在这里：
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
规范帮助文件在这里：
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'
这里有关于 Stack Overflow 的类似讨论，但该帖子的答案是将测试从 ./spec/requests 移动到 ./spec/features - 我已经完成了。
此处的另一个相关讨论，答案是require 'spec_helper'在功能文件的顶部使用......我已经有了。
最后一个观察：似乎关于这个主题的大部分讨论表明问题在于 Capybara 需要位于 spec/features 文件夹中的测试才能访问 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，一直试图找出这是否是一个错误。
* 更新 *
执行彼得的建议后，一切顺利。以下是 authentication_pages_spec 文件中的修改代码（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
