Question

我正在关注Michael Hartl的Rails截屏的旧版本（针对Rails 3）。但是，我正在使用Ruby 2和Rails 4（rspec-rails 3.0.1），通过Google搜索在课程和练习之间进行插值。

我遇到了一个可能错误的匹配器。这是我失败的规范：

RSpec.describe PagesController do
  render_views

    it "has the correct page title" do
      get 'home'
      expect(response).to have_selector('title')
    end
  end

end

以下是错误消息：

Failures:

  1) PagesController GET 'home' has the correct page title
     Failure/Error: expect(response).to have_selector('title')
       expected #<ActionController::TestResponse:0x9e1202c> to respond to `has_selector?`
     # ./spec/controllers/pages_controller_spec.rb:13:in `block (3 levels) in <top (required)>'
     # -e:1:in `<main>'

似乎rspec-rails3中没有像have_selector这样的匹配器。我在their Github page上查了一下，似乎没有提到这个匹配器。

Gemfile：

source 'https://rubygems.org' 
ruby '2.0.0'

gem 'rails', '4.0.0'
gem 'sqlite3'
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder'

group :doc do
  gem 'sdoc', require: false
end

group :development do
  gem 'spring-commands-rspec'
end

group :development, :test do
  gem 'rspec'
  gem 'rspec-rails'
end

Answer 1

have_selector匹配器由Capybara提供。将其添加到您的Gemfile。

ActionController :: TestResponse不响应方法has_selector？
