ruby-on-rails – Rspec可靠性与路由. (Rails示例RoR教程)

我目前正在尝试使用rspec测试我的路由,并且即使我已经正确地遵循了教程中的步骤并且已经通过手动检查和测试路由来验证路由工作,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测试也出现了类似的错误

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

获取此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,看起来是正确的.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,但我想学习如何在实践中使用TDD并使用rspec,但我觉得我不能依赖于rspec这样做…
