rspec - 未定义的局部变量或方法 `root_path'(Rspec Spork Guard)

Question

我有一个新手问题:-)

我正在“创建”一个应用程序，我使用 M. Hartl 的教程来做这件事。但是自从我决定更改routes.rb 以来，我遇到了一些问题。
我知道问题已经发布了，但答案对我不起作用，所以我想我应该问一个新的...

以下是代码:

配置/路由.rb

  root to: 'static_pages#home'
  match '/help', to: 'static_pages#help'
  match '/contact', to: 'static_pages#contact'
  match '/about', to: 'static_pages#about'

规范/请求/static_pages.rb

require 'spec_helper'

describe "Static pages" do

  let(:base_title) { "Vidons" }

  describe "Home page" do
    visit root_path
    it "should have the h1 'Vidons'" do
      page.should have_selector('h1', :text => 'Vidons')
    end
    it "should have the base title" do
      page.should have_selector('title', :text => "#{base_title}")
    end
  end

  describe "Help page" do
    visit help_path
    it "should have the h1 'Aide'" do
      page.should have_selector('h1', :text => 'Aide')
    end
    it "should have the title 'Aide'" do
      page.should have_selector('title', :text => "#{base_title} | Aide")
    end
  end

  describe "About page" do
    visit about_path
    it "should have the h1 'A propos'" do
      page.should have_selector('h1', :text => 'A propos')
    end
    it "should have the title 'A propos'" do
      page.should have_selector('title', :text => "#{base_title} | A propos")
    end
  end

  describe "Contact page" do
    visit contact_path
    it "should have the h1 'Contact'" do
      page.should have_selector('h1', :text => 'Contact')
    end
    it "should have the title 'Contact'" do
      page.should have_selector('title', :text => "#{base_title} | Contact")
    end
  end
end

规范/spec_helper.rb

(我删除了 Rspec.configure 块之一，并保留了 spork prerun 块内的那个)

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

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However,
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'

  # Requires supporting ruby files with custom matchers and macros, etc,
  # in spec/support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    # == Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr
    config.mock_with :rspec

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, remove the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    # If true, the base class of anonymous controllers will be inferred
    # automatically. This will be the default behavior in future versions of
    # rspec-rails.
    config.infer_base_class_for_anonymous_controllers = false
  end
end

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

end

这是 rspec-guard 的响应:

由于弃用警告，我查看了我的 Gemfile，并删除了版本号，以便使用我感兴趣的最后一个 gem:

group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails'
  gem 'guard-rspec'
  gem 'guard-spork'
  gem 'spork'
end

这给了我:

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.

而且它没有改变任何东西......
目前我不太明白，但我希望你们中的一个能给我带来光明;-)

你只需要visit root_path在 before 块内:before { visit root_path }
