Testing Hartl RoR第9.3.1章规范测试失败

我似乎到处都遇到了失败。。。我检查了我的代码，所有的东西都定义好了，拼写检查也在检查中。。。以下是我的失败…：

这里怎么了？？有什么建议吗？

您需要清单7.29中的代码。它是用来编辑Gavatar的

清单7.29。为对象定义可选的：size参数 gravatar_作为助手

app/helpers/users\u helper.rb

module SessionsHelper

  def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
  end

  def signed_in?
    !current_user.nil?
  end

  def current_user=(user)
    @current_user = user
  end

  def current_user
    @current_user ||= User.find_by_remember_token(cookies[:remember_token])
  end

  def current_user?(user)
    user == current_user
  end

  def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
  end

  def redirect_back_or(default)
    redirect_to(session[:return_to] || default)
    session.delete(:return_to)
  end

  def store_location
    session[:return_to] = request.url
  end

您的用户页面规格有以下不匹配的行

describe "index" do
    before do
      sign_in FactoryGirl.create(:user)
      FactoryGirl.create(:user, name: "Bob", email: "bob@example.com")
      FactoryGirl.create(:user, name: "Ben", email: "ben@example.com")
      visit users_path
    end

第9.3章没有Bob电子邮件等，您的用户页面规范中有这些不匹配的行

describe "index" do
    before do
      sign_in FactoryGirl.create(:user)
      FactoryGirl.create(:user, name: "Bob", email: "bob@example.com")
      FactoryGirl.create(:user, name: "Ben", email: "ben@example.com")
      visit users_path
    end

第9.3章没有鲍勃的电子邮件等
