我的 Rails 模型验证测试有问题。验证正常运行（它拒绝格式不正确的电子邮件），但测试失败。

这是我的 user.rb 模型中的重要信息

class User < ActiveRecord::Base

  attr_accessible :first_name, :middle_name, :last_name, :email, :password, :address, :city, :state, :zip_code, :phone_home, :phone_cell, :phone_work, :status_id, :password_confirmation, :is_test, :parent_paramed_id, :company, :logo, :is_agent, :is_paramed, :additional_emails

  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

  validate :validates_single_email_format
  validates_presence_of :email
  validates_uniqueness_of :email

  def validates_single_email_format
    User.validates_single_email_format(self.email)
  end

  def self.validates_single_email_format(email)
    email =~ VALID_EMAIL_REGEX
  end

这是我的 user_spec.rb

describe User do
  context "validate email address on create" do
    before { User.delete_all }

    context "fails" do
      let(:user) { FactoryGirl.build(:user, :email => 'blah') }
      before { user.save; binding.pry }
      specify { user.should_not be_valid }
    end

    context "succeeds" do
      let(:user) { FactoryGirl.build(:user, :email => 'matt@google.com' ) }
      before { user.save; binding.pry }
      specify { user.should be_valid }
    end

  end
end

这是此测试的输出，因为它在每次保存后使用 binding.pry 执行，以查看调用保存后用户对象的样子：

Failures:

  1) User validate email address on create fails
     Failure/Error: specify { user.should_not be_valid }
       expected valid? to return false, got true
     # ./spec/models/user_spec.rb:97:in `block (4 levels) in <top (required)>'

Finished in 16.9 seconds
2 examples, 1 failure

Failed examples:

rspec ./spec/models/user_spec.rb:97 # User validate email address on create fails

出于某种原因，失败的测试返回 true，即使它认为电子邮件值为“blah”。如果我在对象上运行验证方法，它会通过说不匹配来响应。但由于某种原因，“预期有效？” 测试返回真。我不确定为什么会发生这种情况。

任何帮助将不胜感激。我可以在现有问题中找到任何类似的问题。

两件事情。您的validates_single_email_format方法不仅需要 return false，还必须调用errors.add(:email, "Email is in wrong format!")才能产生效果。

该valid?方法不仅运行验证，还将错误消息添加到最后errors并errors为空，则认为模型有效。

无论如何，您可以使用：

validates_format_of :email, with: VALID_EMAIL_REGEX

验证的语法不正确。在两行中尝试这个正确的一个。

EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, presence: true, uniqueness: true, format: {with: EMAIL_REGEX}
