Hartl Rails教程，第6章，清单6.17测试失败

Question

在我达到6.17之前，我的测试一直在变绿。有人能帮我看看是怎么回事吗？

以下是错误和失败：

ERROR["test_layout_links", SiteLayoutTest, 0.011797307059168816]

这是我的user.rb文件：

class User < ApplicationRecord
  validates :name, presence: true, length: { maximum: 50 }
  validates :email, presence: true, length: { maxmium: 255 }
end

这是我的user_test.rb文件：

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
end

这是我的site_layout_test.rb文件，因为它是以某种方式涉及到的：

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

 test "layout links" do
   get root_path
   assert_template 'static_pages/home'
   assert_select "a[href=?]", root_path, count: 2
   assert_select "a[href=?]", help_path
   assert_select "a[href=?]", about_path
   assert_select "a[href=?]", contact_path
   get contact_path
   assert_select "title", full_title("Contact")
   get signup_path
   assert_select "title", full_title("Sign Up")
 end
end

我已经对这些文件进行了排印，似乎找不到正在发生的事情。谢谢你能提供的任何帮助。

Answer 1

对user.rb文件进行拼写检查。您错选了maximum for for

代码应该是

 class User < ApplicationRecord
      validates :name, presence: true, length: { maximum: 50 }
      validates :email, presence: true, length: { maximum: 255 }
 end
