Question

我正在关注Michael Hartl的Ruby on Rails教程。我的测试全部通过，直到我迁移数据库并添加了最后2个测试。有些东西搞砸了，因为即使我删除了最后2个测试，所有测试现在都失败了。我不确定我是否在迁移或其他方面犯了一些错误。

这就是我使用的：

$ bundle exec rake db:migrate
$ bundle exec rake db:test:prepare
$ bundle exec rspec spec/

这是完全失败的user_spec文件：

require 'spec_helper'

describe User do
  before do
   @user = User.new(name: "Example User", email: "user@example.com", password: "foobar", password_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 }

  describe "when name is not present" do
  before { @user.name = " " }
  it { should_not be_valid }
  end

  describe "when email is not present" do
    before { @user.email = " "}
    it { should_not be_valid }

  end

  describe "when name is too long" do
    before { @user.name = "a"*51 }
    it { should_not be_valid }
  end

  describe "when email format is invalid" do
    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

    describe "when email format is valid" do
        it "should be valid" do
            addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn]
                addresses.each do |valid_address|
                    @user.email = valid_address
                    @user.should be_valid
                end
            end
        end

    describe "when email address is already taken" do
        before do
            user_with_same_email = @user.dup
            user_with_same_email.email = @user.email.upcase
            user_with_same_email.save
        end

        it { should_not be_valid }
    end


    describe "when password is not present" do
      before { @user.password = @user.password_confirmation = " " }
      it { should_not be_valid }
    end 

    describe "when password doesn't match confirmation" do
      before { @user.password_confirmation = "mismatch" }
      it { should_not be_valid }
    end

    describe "when password confirmation is nil" do
      before { @user.password_confirmation = nil }
      it { should_not be_valid }
    end
end

这是迁移文件：

class AddPassswordDigestToUsers < ActiveRecord::Migration
  def change
    add_column :users, :password_digest, :string
  end
end

EDIT2 - 我刚刚从规范的第一行删除password: "foobar", password_confirmation: "foobar"，现在我只得到5个错误（这与密码相关的错误是正确的）

EDIT1 - 这是失败的测试

Answer 1

从书中可以看出：

将所有内容放在一起会产生代码清单6.28中的（失败）测试。我们将让他们通过第6.3.4节。

测试应该失败。一旦密码实现完成，它们将在稍后的教程中通过。

现在，解释为什么他们失败了：

在您创建用户的行（您的before块）上，您将password属性传递给构造函数，但该属性尚不存在，因此您的模型会抱怨你看到的错误。在教程中，此属性稍后创建。

RSpec：所有测试都失败了
