Question

嘿，我是Rails和Rspec的新手，我只是阅读Michael Hartls Tutorial。我坚持运行static_pages_spec.rb

C:/Rails/sample_app/spec/requests/static_pages_spec.rb:48:in `block (2 levels) i
n <top (required)>': undefined local variable or method `root_path' for #<Class:
0x55795b0> (NameError)

static_pages_spec.rb：

require 'spec_helper'

describe "Static pages" do

  subject { page }

  shared_examples_for "all static pages" do
    it { should have_selector('h1', text: heading) }
    it { should have_title(full_title(page_title)) }
  end

  describe "Home page" do
    before { visit root_path }
    let(:heading)    { 'Sample App' }
    let(:page_title) { '' }

    it_should_behave_like "all static pages"
    it { should_not have_title('| Home') }
  end

  describe "Help page" do
    before { visit help_path }

    let(:heading)    { 'Help' }
    let(:page_title) { 'Help' }

    it_should_behave_like "all static pages"
  end

  describe "About page" do
    before { visit about_path }

    let(:heading)   { 'About' }
    let(:page_title){ 'About' }

    it_should_behave_like "all static pages"
  end

  describe "Contact page" do
    before { visit contact_path }

    let(:heading)   { 'Contact' }
    let(:page_title){ 'Contact' }

    it_should_behave_like "all static pages"
  end 
  describe "should have the right links on the layout" do
    visit root_path
    click_link "About"
    expect(page).to have_title(full_title('About Us'))
    click_link "Help"
    expect(page).to have_title(full_title('Help'))
    click_link "Contact"
    expect(page).to have_title(full_title('Contact'))
    click_link "Home"
    click_link "Sign up now!"
    expect(page).to have_title(full_title('Sign up'))
    click_link "sample app"
    expect(page).to have_title(full_title('Sample App'))
  end
end

我不知道出了什么问题。我使用了这个测试〜20次，其中包含“root_path”，但它之前从未出现过麻烦。如果它有用，请点击这里我的routes.rb：

SampleApp::Application.routes.draw do
    root  'static_pages#home'
    match '/help',    to: 'static_pages#help',    via: 'get'
    match '/about',   to: 'static_pages#about',   via: 'get'
    match '/contact', to: 'static_pages#contact', via: 'get'
        match '/signup',  to: 'users#new',            via: 'get'
    get "users/new"
end

我只是照看了我在过去20分钟内编辑的所有文件，但没有看到任何可以解释这一点的文件。

＆＃34;您无法在spec类中调用路径方法。它应该在它的块中。＆＃34; 看看这个：Rspec undefined local variable or method root_path

Rails URL Helpers NameError
