模型驗證失敗FactoryGirl Rspec，驗證似乎被忽略

Question

我有我的Rails模型驗證測試的問題。驗證功能正常（拒絕格式不正確的電子郵件），但測試失敗。

這是我從我的user.rb模型

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 

重要信息，這是我的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 

，因爲它是一個結合執行這是本次測試的輸出。在每次保存之後撬動以查看在保存被調用後用戶對象的樣子：

    91: context "validate email address on create" do 
    92:  before { User.delete_all }

    97:  specify { user.should_not be_valid } 
    98:  end

    101:  let(:user) { FactoryGirl.build(:user, :email => 'matt@google.com') }

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 

對於某些即使它認爲電子郵件的值爲「無效」，但失敗的測試返回true。如果我在對象上運行驗證方法，它會迴應說沒有匹配。但由於某種原因，「預計有效？」測試返回true。我不確定爲什麼會發生這種情況。

任何幫助將不勝感激。我可以在現有的問題中找到任何類似的問題。

Answer 1

兩件事。您的validates_single_email_format方法不僅需要返回false，還必須呼叫errors.add(:email, "Email is in wrong format!")纔會產生一些效果。

的valid?方法不只是運行驗證，這也增加了錯誤消息errors和errors是空到底，那麼該模型被認爲是有效的。

不管怎麼說，你可以使用：

validates_format_of :email, with: VALID_EMAIL_REGEX 

Answer 2

驗證的語法不正確。只用兩行試試這個正確的。

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