Rails的模型失敗的測試斷言

這裏是我的型號代碼：Rails的模型失敗的測試斷言

class User < ActiveRecord::Base 

    validates :email, :presence => true, 
        :uniqueness => true, 
        :format => { 
        :with => %r{^([0-9a-zA-Z]([-\.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$}, 
        :message => "You must enter a valid email address." 
        } 

    validates :password, :presence => true, 
         :confirmation => true, 
         :length => { :in => 6..20 } 

    validates :password_confirmation, :presence => true 

    validates :firstname, :presence => true 

    validates :lastname, :presence => true 

end

而且我的測試：

require 'test_helper' 

class UserTest < ActiveSupport::TestCase 

    test "user email must not be empty" do 
    user = User.new 
    assert user.invalid? 
    assert user.errors[:email].any? 
    end 

    test "user password must be between 6 and 20 characters" do 
    user = User.new(:email => "[email protected]", 
        :firstname => "sergio", 
        :lastname => "tapia") 

    user.password = "123" 
    assert user.invalid? 

    user.password = "" 
    assert user.invalid? 

    #6 characters. 
    user.password = "123456" 
    assert user.valid? 

    #20 characters. 
    user.password = "123456789" 
    assert user.valid? 

    #21 characters. 
    user.password = "123456789" 
    assert user.invalid? 

    end 

end

而測試的結果：

[email protected]:~/code/ManjarDeOro$ rake test:units 
Run options: 

# Running tests: 

.F 

Finished tests in 0.105599s, 18.9395 tests/s, 47.3488 assertions/s. 

    1) Failure: 
test_user_password_must_be_between_6_and_20_characters(UserTest) [/home/sergio/code/ManjarDeOro/test/unit/user_test.rb:24]: 
Failed assertion, no message given. 

2 tests, 5 assertions, 1 failures, 0 errors, 0 skips

因此斷言失敗上此位：

#6 characters. 
user.password = "123456" 
assert user.valid?

那麼發生了什麼？我對斷言的條件是否有誤？我認爲一個6字符的密碼會將我的「用戶」對象變成.valid。

我是新來的Rails。

您忘記添加'password_confirmation =「123456」'使用戶有效 – yoavmatchulsky 2012-02-03 16:26:25

謝謝，我錯過了。 – 2012-02-03 16:33:20

@yoavmatchulsky應該添加作爲答案。 – tadman 2012-02-03 16:36:37

您的用戶未驗證，因爲您錯過了用戶的password_confirmation部分。

user.password = "123456" 
user.password_confirmation = "123456" 
assert user.valid?
