Ruby on Rails用户测试失败

Question

做Ruby on Rails教程和运行测试时出现奇怪的错误消息。 我user_test.rb：

require 'test_helper' 

class UserTest < ActiveSupport::TestCase 
    def setup 
    @user = User.new(name: "Example User", email: "user@example.com", password: "wordpass", password_confirmation: "wordpass") 
    end 
    test "should be valid" do 
    assert @user.valid? 
    end 

    test "name should be present" do 
    @user.name="  " 
    assert_not @user.valid? 
    end 

    test "email should be present" do 
    @user.email= "  " 
    assert_not @user.valid? 
    end 
    test "name should not be too long" do 
    @user.name= "a" * 51 
    assert_not @user.valid? 
    end 

    test "email should not be too long" do 
    @user.email= "a" * 256 
    assert_not @user.valid? 
    end 
    test "email validation should accept valid addresses" do 
    valid_addresses = %w[user@example.com USER@foo.COM A_US-ER@foo.bar.org 
         first.last@foo.jp alice+bob@baz.cn] 
    valid_addresses.each do |valid_address| 
     @user.email = valid_address 
     assert @user.valid? , "#{valid_address.inspect} should be valid" 
    end 
    end 

    test "email validation should reject invalid addresses" do 
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example. 
          foo@bar_baz.com foo@bar+baz.com] 
    invalid_addresses.each do |invalid_address| 
     @user.email = invalid_address 
     assert_not @user.valid?, "#{invalid_address.inspect} should be invalid" 
    end 
    end 
    test "email addresses should be unique" do 
    duplicate_user = @user.dup 
    duplicate_user.email = @user.email.upcase 
    @user.save 
    assert_not duplicate_user.valid? 
    end 
    test "password should be a minimum length" do 
    @user.password = @user.password_confirmation = "a" * 5 
    assert_not @user.valid? 
    end 

end 

的user.rb：

class User < ActiveRecord::Base 

    attr_accessor :name, :email , :password, :password_confirmation 
    before_save { self.email = email.downcase } 
    validates :name, presence: true, length: { maximum: 50 } 
    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, 
      uniqueness: { case_sensitive: false } 
    has_secure_password 
    validates :password, length: { minimum: 6 } 
end 

一个错误似乎是由用户定义，但我无法找到错误的根源。是否与user.rb文件中的“验证”相关？任何帮助都感激不尽 ！！

在此先感谢您的帮助！

Answer 1

你是对的，其中一个错误是由于@user在第一个测试中无效。执行以下操作中轨控制台，这应该对用户模型打印出的错误：

@user = User.new(name: "Example User", email: "user@example.com", password: "wordpass", password_confirmation: "wordpass") 
@user.valid? 
pp @user.errors 

Answer 2

在user.rb尝试不同的正则表达式

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

Answer 3

也一切正常。只需运行命令

rake db:test:prepare 

，如果这不工作或者再

$rake db:delete 
rake db:create 
rake db:migrate
