Rails教程5.3.0 TDD錯誤：「未定義方法訪問」

在線學習Hartl教程後，似乎無法找到第5章第3.0節的解決方案。在本教程的這一點，我似乎應該通過在「spec/support/utilities.rb」中定義full_title然後編輯「spec/requests/static_pages_spec.rb」文件來讓我的rspec代碼更加簡潔。Rails教程5.3.0 TDD錯誤：「未定義方法訪問」

這裏是我的「投機/支持/ utilities.rb」：

def full_title(page_title) 
    base_title = "Ruby on Rails Tutorial Sample App" 
    if page_title.empty? 
    base_title 
    else 
    "#{base_title} | #{page_title}" 
    end 
end

和我的「投機/請求/ static_pages_spec.rb」：

require 'spec_helper' 

describe "Static pages" do 

subject { page } 

    describe "Home page" do 
    before { visit root_path } 

    it { should have_content('Sample App') } 
    it { should have_title(full_title('')) } 
    it { should_not have_title('| Home') } 
    end 

    describe "Help page" do 
    before { vist root_path } 

    it { should have_content('Help') } 
    it { should have_title(full_title('Help')) } 
    end 

    describe "About page" do 
    before { visit root_path} 

    it { should have_content('About') } 
    it { should have_title(full_title('About')) } 
    end 

    describe "Contact page" do 
    before { visit contact_path } 

    it { should have_content('Contact') } 
    it { should have_title(full_title('Contact')) } 
    end 
end

和我的「spec_helper.rb」：

require 'rubygems' 
require 'spork' 

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

    # 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} 

    # Checks for pending migrations before tests are run. 
    # If you are not using ActiveRecord, you can remove this line. 
    ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration) 

    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 

    # 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 

    # Run specs in random order to surface order dependencies. If you find an 
    # order dependency and want to debug it, you can fix the order by providing 
    # the seed, which is printed after each run. 
    #  --seed 1234 
    config.order = "random" 
    config.include Capybara::DSL 
    end 
end 

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

end

當我運行：

$ bundle exec rspec spec/requests/static_pages_spec.rb

我得到：

我已經看到了其他職位，這種錯誤可能是由於缺乏「水豚」，因爲「訪問」是一個水豚方法。我檢查了我的寶石文件，並將其顯示水豚：

我不知道什麼是需要做visit用於測試的有效方法是什麼？

您實際上已經拼錯了單詞，請訪問：

before { vist root_path }

，並在測試通過，您需要將關於和幫助測試的路徑更改爲各自的路徑。

例如，如果正在測試的幫助頁面，但不是逛help_path，您正在訪問的root_path

describe "Help page" do before { visit root_path }

也是一樣的About page。

Thanks！我在「describe」幫助頁面「do」下更正了「visit」。但是，我不確定你的意思是將_About_和_Help_測試的路徑更改爲各自的路徑。對不起，我對編程很陌生。 – kyu1012

@ kyu1012我剛剛編輯了我的答案。 – PericlesTheo

啊我現在明白了。我會盡快進行更改，並讓您知道發生了什麼。謝謝！ – kyu1012

我有同樣的情況，但我的路的是好和測試失敗

解決了！也許它可以幫助某人所有關於水豚2.x的這些錯誤，只是像星號一樣的變化，並且您的測試將通過;）

require 'spec_helper' 

describe "Static pages" do 

    subject { page } 

    describe "Home page" do 
    before { visit root_path } 

    it { should have_content('some App') } 
    it { should have_title(full_title('')) } 
    it { should_not have_title('| Home') } 
    end 

    describe "Help page" do 
    before { visit help_path } 


**it { page.should have_content('Help') } 
    it { page.has_title?(full_title('Help')) }** 
    end 

    describe "About page" do 
    before { visit about_path } 

    **it { page.should have_content('About') } 
    it { page.has_title?(full_title('About Us')) }**
