未定义的方法“访问”（使用 rspec 和水豚）

Question

在尝试运行规范文件进行集成测试时，我看到：

undefined method `visit' for #<Class:0xab9a140> (NoMethodError)

我搜索了这个网站并找到了几个解决我问题的方法，这些是我已经尝试过的解决方案（没有成功）：

• 在规范/功能而不是规范/请求下添加了文件（它们一直存在）

• 在我的规范文件中添加include Capybara::DSL - 这很有趣。当我添加这个时，我不再出现上述错误并开始出现另一个错误消息：

  • undefined method 'expect' for #<Class:0x9d2a088> (NoMethodError)
• 在规范测试中将describe 替换为feature。 （没有变化）

尝试运行包含visit 方法的规范的结果：

我的 Gemfile：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'

group :development,:test do
  gem 'rspec-rails'
  gem 'pg','0.15.1'
  gem 'watchr'
  gem 'selenium-webdriver'
  gem 'capybara'
  gem 'spork-rails'
  gem 'guard-spork'
  gem 'childprocess'
end

gem 'sass-rails', '~> 4.0.1'

gem 'uglifier', '>= 2.1.0'

gem 'coffee-rails', '~> 4.0.1'

gem 'jquery-rails','3.0.4'

gem 'turbolinks','1.1.1'

gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

我的 spec_helper.rb 文件

require 'rubygems'
require 'spork'

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"
    # Disable the old-style object.should syntax.
    config.expect_with :rspec do |c|
       c.syntax = :expect
    end
  end
end

Spork.each_run do

end

实际测试（是的，在spec/features文件夹下）

require 'spec_helper'

describe "Projects" do
  describe "Projects index" do

    it "should show the string 'Projetos'" do

      visit '/projects'
      expect(page).to have_content('Projetos')

    end
  end

  describe 'Add and delete a project' do

    visit '/projects/new'

    expect(page).to have_content('Novo')

  end 

end

我正在寻找有关我的问题的建议和指示。

P.S.：我正在运行rails (4.0.1)、capybara (2.2.0)、rspec-core (2.14.7)rspec-rails (2.14.0)

我找到了问题....我在第二次调用 visit 时错过了 it ... do ... end 块...对此感到抱歉，感谢所有帮助过我的人。
