我正在研究 michael hartl rails 教程。目前在第 6 章。编辑 user_spec.rb 文件后，我尝试运行测试，但我遇到了巨大的失败：

这是我的 User_spec.rb 文件：

 require 'spec_helper'

 describe User do

before  do
    @user = User.new(name: "Example User", email: "user@example.com",
                     password: "foobar",  
    passsword_confirmation: "foobar") 
end

subject { @user }

it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should respond_to(:password) }
it { should respond_to(:password_confirmation) }

it { should be_valid }

    it "should be invalid" do
        addresses = %w[user@foo,com user_at_foo.org example.user@foo.   
                        foo@bar_baz.com foo@bar+baz.com]
        addresses.each do |invalid_address|
            @user.email = invalid_address
            @user.should_not be_valid
        end
    end
end

            @user.should be_valid
        end
    end
end

    before do
        user_with_same_email = @user.dup
        user_with_same_email.email = @user.email.upcase

end

    let(:found_user) { User.find_by_email(@user.email) }

    describe "with valid password" do
        it { should == found_user.authenticate(@user.password) }
    end

    describe "with invalid password" do
        let(:user_for_invalid_password) {   
 found_user.authenticate("invalid") }

        it { should_not == user_for_invalid_password }
        specify { user_for_invalid_password.should be_false }
    end
end

describe "with a password that's too short" do
    before { @user.password = @user.password_confirmation = "a" * 5 }
    it { should be_valid }
end

describe "return value of authenticate method" do
    before { @user.save }
    let(:found_user) { User.find_by_email(@user.email) }    

    describe "with valid password" do
        it { should == found_user.authenticate(@user.email) }
    end

    describe "with invalid password" do
        let(:user_for_invalid_password) { 
found_user.authenticate("invalid") }

        it { should_not == user_for_invalid_password }
        specify { user_for_invalid_password.should be_false }
    end
end
end

这是我的问题：

首先也是最明显的：

我应该怎么做才能通过这个测试？错误消息没有给我任何线索。

第二

当我这样创建新用户时：

irb(main):002:0> user = User.create(name: "Example user", email: "User@example>
  ←[1m←[36m (0.0ms)←[0m  ←[1mbegin transaction←[0m
  ←[1m←[35mUser Exists (0.0ms)←[0m  SELECT 1 AS one FROM "users" WHERE LOWER("us
 ers"."email") = LOWER('User@example.com') LIMIT 1
  ←[1m←[36m (0.0ms)←[0m  ←[1mrollback transaction←[0m
=> #<User id: nil, name: "Example user", email: "User@example.com", created_at:
nil, updated_at: nil, password_digest: nil>

然后我尝试保存这个用户，我得到“错误”的响应：

irb(main):004:0> user.save
  ←[1m←[35m (0.0ms)←[0m  begin transaction
  ←[1m←[36mUser Exists (1.0ms)←[0m  ←[1mSELECT 1 AS one FROM "users" WHERE LOWER
  ("users"."email") = LOWER('User@example.com') LIMIT 1←[0m
  ←[1m←[35m (0.0ms)←[0m  rollback transaction
  => false

这个问题与开头提到的测试失败有关吗？

最后一个问题：什么意思？

BUDDY：注意下面的代码（这是你的代码）。它来自 user_spec.rb。您连续两次复制/粘贴“无效密码”。其他一切都很好，您只是在规范文件中打错了字。

 describe "with invalid password" do
        let(:user_for_invalid_password) {   
 found_user.authenticate("invalid") }

        it { should_not == user_for_invalid_password }
        specify { user_for_invalid_password.should be_false }
    end
end

describe "with a password that's too short" do
    before { @user.password = @user.password_confirmation = "a" * 5 }
    it { should be_valid }
end

describe "return value of authenticate method" do
    before { @user.save }
    let(:found_user) { User.find_by_email(@user.email) }    

    describe "with valid password" do
        it { should == found_user.authenticate(@user.email) }
    end

    describe "with invalid password" do
        let(:user_for_invalid_password) { 
found_user.authenticate("invalid") }

        it { should_not == user_for_invalid_password }
        specify { user_for_invalid_password.should be_false }
    end
end
end

你的意思是user.rb？

 class User < ActiveRecord::Base
   attr_accessible :email, :name, :password, :password_confirmation
   has_secure_password

    before_save { |user| user.email = email.downcase }

    validates :name,  presence: true, length: { maximum: 50 }
    VALID_EMAIL_REGEX = /\A[w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
    validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
               uniqueness: { case_sensitive: false }
    validates :password, presence: true, length: { minimum: 6 }
    validates :password_confirmation, presence: true

 end
