ruby-on-rails – 为什么我的规范/支持文件没有被rspec选中？

规格/支持/ utilities.rb

include ApplicationHelper


def sign_in(user)
  visit new_user_session_path
  fill_in "Email",with: user.email
  fill_in "Password",with: user.password
  click_button "Sign in"
end

我的守护文件：

require 'active_support/core_ext'


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

guard 'rspec',:version => 2,: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 request specs
  watch(%r{^app/views/(.+)/.*.(erb|haml)$})          { |m| "spec/requests/#{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' }

  watch(%r{^app/controllers/(.+)_(controller).rb$})  do |m|
    ["spec/routing/#{m[1]}_routing_spec.rb","spec/acceptance/#{m[1]}_spec.rb",(m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
                       "spec/requests/#{m[1].singularize}_pages_spec.rb")]
  end
  watch(%r{^app/views/(.+)/}) do |m|
    (m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
                       "spec/requests/#{m[1].singularize}_pages_spec.rb")
  end

end

在我的集成测试requests / link_pages_spec.rb中,我尝试做这样的事情,但它给了我一个错误

require 'spec_helper'

describe "Link pages" do

  subject { page }

  describe 'creating a link' do

    before do
      sign_in FactoryGirl.create(:user)
      visit new_link_path
    end

    describe "with invalid information" do
      it "should not create a link" do
        expect { click_button 'Create Link' }.not_to change(Link,:count)
      end
    end

  end

end

错误：

Failure/Error: sign_in FactoryGirl.create(:user)
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x007f8ebb563e10>
     # ./spec/support/utilities.rb:5:in `sign_in'
     # ./spec/requests/link_pages_spec.rb:10:in `block (3 levels) in <top (required)>'

奇怪的是,如果我删除链接页面规范中的describe块,则没有错误..
