Question

My Rails项目的'spec'文件夹包含以下内容：

1）'controllers'子文件夹： a）'pages_controller'规范文件（带有相应的“描述PagesController do”语句）：

require 'spec_helper'

describe PagesController do
  render_views

  before(:each) do
    @base_title = "Ruby on Rails Tutorial Sample App | "
  end

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

    it "should have the right title" do
      get 'home'
      response.should have_selector("title", content: @base_title+"Home")
    end
  end

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

    it "should have the right title" do
      get 'contact'
      response.should have_selector("title", content: @base_title+"Contact")
    end
  end

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

    it "should have the right title" do
      get 'about'
      response.should have_selector("title", content: @base_title+"About")
    end
  end

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

    it "should contain the right title" do
      get 'help'
      response.should have_selector("title", content: @base_title+"Help")
    end
  end

end

b）'users_controller'规范文件（带有相应的“describe UsersController do”语句）：

require 'spec_helper'

describe UsersController do
  render_views

  describe "GET '/new'" do

    it "should be successful" do
      get 'new'
      response.should be_success
    end

    it "should have the right title" do
      get 'new'
      response.should have_selector("title", content: "Sign up")
    end

  end

end

2）'requests'子文件夹包含以下'layout_links'规范文件：

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 '/content'" 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'
    response.should have_selector('title', content: 'Help')
  end

  it "should have a signup page at '/signup'" do
    get '/signup'
    response.should have_selector("title", content: "Sign up")
  end

end

我最初将以下代码添加到我的“users_controller”文件中：

it "should have a signup page at '/signup'" do
  get '/signup'
  response.should have_selector("title", content: "Sign up")
end

我运行时测试失败了，但是当我将它添加到'layout_links'规范文件中时，它就通过了。这告诉我，我遗漏了RSpec和/或集成测试的一些基本方面。如果有必要，我很乐意重新提出这个问题，使其更具普遍性。

Answer 1

你的预感是正确的，这里有一些关于配置的约定。

控制器测试将在指定的控制器上运行。因此，PagesController测试将会有效......好吧，PagesController。因此，get 'home'行将尝试在home控制器中获取Pages操作，Pages控制器将承担所有这些测试。除非您的Pages控制器执行signup操作，否则会出错。

requests类型测试用于集成测试，不承担控制器。

为什么这个RSpec在一个文件中传递而在另一个文件中失败？
