урок ruby ​​on rails, глава 6, ошибка при проверке электронной почты

Question

Я нахожусь в главе 6, перечисляя 6.21, добавляя REGEX для правильной проверки электронной почты и дважды проверил user.rb и user_test.rb и не могу понять, как я получаю следующую ошибку.

FAIL["test_should_be_valid", UserTest, 6.092359365000448]
 test_should_be_valid#UserTest (6.09s)
        Expected false to be truthy.
        test/models/user_test.rb:10:in `block in <class:UserTest>'

вот мой user.rb

class User < ApplicationRecord
  validates :name, presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
  format: { with: VALID_EMAIL_REGEX }
end

а вот мой user_test.rb

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  def setup
    @user = User.new(name: "Example User", email: "user@example,com")
  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" * 244 + "@example.com"
    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
end

Answer 1

def setup
  @user = User.new(name: "Example User", email: "user@example,com")
end
