Question

我正在尝试编写一个验证电子邮件地址唯一性的测试。

这是用于在Rails 4.0.0中创建新用户帐户并使用has_secure_password。

我收到此错误：

User should require case sensitive unique value for email
     Failure/Error: it { should validate_uniqueness_of(:email) }
     RuntimeError:
       Password digest missing on new record
     # ./spec/models/user_spec.rb:8:in `block (2 levels) in <top (required)>'

user_spec.rb：

require "spec_helper"

describe User do
  it { should validate_presence_of(:email) }
  it { should validate_presence_of(:full_name) }
  it { should validate_presence_of(:password_digest) }
  it { should validate_uniqueness_of(:email) }
end

以下是用户模型：

class User < ActiveRecord::Base
  has_secure_password

  validates :email, presence: true, uniqueness: true
  validates :full_name, presence: true
  validates :password_digest, presence: true
end

错误消息的含义是什么？我做错了什么？

Answer 1

问题解决了。我在每次测试之前添加了一行来创建一个User对象，现在错误就消失了。

describe User do        
  # this before section solved the problem
  before(:each) do
    User.create(
      full_name: "Bob",
      email: "bob@bob.com",
      password: "bob",
      password_confirmation: "bob"
    )
  end

  it { should validate_presence_of(:email) }
  it { should validate_presence_of(:full_name) }
  it { should validate_presence_of(:password_digest) }

  it { should validate_uniqueness_of(:email) }
end

回答你的问题：https://github.com/thoughtbot/shoulda-matchers/issues/371

似乎当前的解决方案是在测试唯一性之前创建新记录。简而言之，这是潜在的问题：

似乎has_secure_password的Rails 4版本增加了一个 before_create以确保填写password_digest;然而， Rails 3版本没有这个检查。

Ruby On Rails应该测试错误：新记录上缺少密码摘要
