我按照第 7 章 Ruby on Rails 教程中的所有说明进行操作，当我最终运行 $ Bundle exec rspec spec/ 时，会显示一系列错误。我仔细检查了我的代码是否有任何拼写错误或遗漏了任何符号。一切似乎都很好。您能否解释一下错误并告诉我哪里出错了？？？谢谢

USER_PAGES_SPEC.RB

require 'spec_helper'

describe "User pages" do

  subject { page }

  describe "signup page" do
  before {visit signup_path}

    it { should have_selector('h1',    text: 'Sign ') }
    it { should have_selector('title', text: full_title('Sign up')) }
  end

 describe "profile page" do
    let(:user) { FactoryGirl.create(:user) }

    before { visit user_path(user) }

    it { should have_selector('h1',    text: user.name) }
    it { should have_selector('title', text: user.name) }
  end

   describe "signup" do

    before { visit signup_path }

    let(:submit) { "Create my account" }

    describe "with invalid information" do
      it "should not create a user" do
        expect { click_button submit }.not_to change(User, :count)
      end
    end

    describe "with valid information" do
      before do
        fill_in "Name",         with: "Example User"
        fill_in "Email",        with: "user@example.com"
        fill_in "Password",     with: "foobar"
        fill_in "Confirmation", with: "foobar"
      end

      it "should create a user" do
        expect { click_button submit }.to change(User, :count).by(1)
      end

      describe "after saving a user" do
        before {click_button submit}

        let (:user) {user.find_by_email("user@example.com")}

        it {should have_selector('title', text:user.name)}
    end
  end
end
end

USER_CONTROLLER.RB

class UsersController < ApplicationController

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])

    if @user.save

    sign_in @user

    flash[:success] = "Welcome to the Sample App!"

    redirect_to @user

    else

     render 'new'
    end
  end
end

命令行上显示的错误

1) 未定义的方法 full_title

你定义了吗？

2) 期望带有文本“Michael Hartl”的css“title”返回一些东西

你还没有<title>Michael Hartl</title>输出html。

3, 4) 未定义的方法sign_in

你在哪里定义的？

更正您的代码，所有测试都将通过。
