在学习 Ruby on Rails 5.2 上的示例教程时，我对 Rspec 感到沮丧。

我目前正在尝试使用 rspec 测试我的路由，即使我尽我所知正确地遵循了教程中的步骤并且通过手动检查和测试路由来验证路由是否有效，测试总是以失败的形式返回我。

例如，layout_links_spec.rb 如下所示：

require 'spec_helper'

describe "LayoutLinks" do

    it "should have a Home page at '/'" do
        get '/'
        response.should have_selector('title', :content => "Home")
    end

    it "should have a Contact page at '/contact'" do
        get '/contact'
        response.should have_selector('title', :content => "Contact")
    end

    it "should have an About page at '/about'" do
        get '/about'
        response.should have_selector('title', :content => "About")
    end

    it "should have a Help Page at '/help'" do
        get '/help'
        reponse.should have_selector('title', :content => "Help")
    end

end

我的路线看起来像：

SampleApp::Application.routes.draw do
  match '/contact', :to => 'pages#contact'
  match '/about', :to => 'pages#about'
  match '/help', :to => 'pages#help'
  get "pages/home"
  get "pages/contact"
  get "pages/about"
  get "pages/help"

  root :to => 'pages#home'
end

Rspec 返回此失败：

  5) LayoutLinks should have a Home page at '/'
     Failure/Error: get '/'
     ActionController::RoutingError:
       No route matches [GET] "/"
     # ./spec/requests/layout_links_spec.rb:6:in `block (2 levels) in <top (required)>'

  6) LayoutLinks should have a Contact page at '/contact'
     Failure/Error: get '/contact'
     ActionController::RoutingError:
       No route matches [GET] "/contact"
     # ./spec/requests/layout_links_spec.rb:11:in `block (2 levels) in <top (required)>'

  7) LayoutLinks should have an About page at '/about'
     Failure/Error: get '/about'
     ActionController::RoutingError:
       No route matches [GET] "/about"
     # ./spec/requests/layout_links_spec.rb:16:in `block (2 levels) in <top (required)>'

  8) LayoutLinks should have a Help Page at '/help'
     Failure/Error: get '/help'
     ActionController::RoutingError:
       No route matches [GET] "/help"
     # ./spec/requests/layout_links_spec.rb:21:in `block (2 levels) in <top (required)>'

我的 pages_controller_spec.rb 测试也出现类似错误

  describe "GET 'home'" do
    it "should be successful" do
      get 'home'
      response.should be_success
    end

得到这个 rspec 错误：

  1) PagesController GET 'home' should be successful
     Failure/Error: get 'home'
     ActionView::Template::Error:
       undefined local variable or method `root_path' for #<#<Class:0x00000103e8b210>:0x00000103e87de0>
     # ./app/views/layouts/_header.html.erb:3:in `_app_views_layouts__header_html_erb__1560745193027372362_2179584160'
     # ./app/views/layouts/application.html.erb:10:in `_app_views_layouts_application_html_erb__2627526215404316040_2176993080'
     # ./spec/controllers/pages_controller_spec.rb:15:in `block (3 levels) in <top (required)>'

我用教程检查了我的代码，它看起来正确。如果我输入 url localhost:3000/home 或 /about 等，我会进入正确的页面，表明它必须正确路由。我可以继续学习本教程，但我想学习如何做 TDD 并在实践中使用 rspec，但我觉得我不能依赖 rspec 来做到这一点......

我遇到了完全相同的问题，并且快要扔东西了。
