Ruby on rails Rails教程-调试bundle exec rake测试

我是新用户，所以请不要杀我。我一直在学习MichaelHartl的Rails教程第9章，并取得了一些成功。在运行“bundle exec rake test”命令时，我遇到了3个错误。这些不会影响测试的状态，因此根据Hartl先生的规范，我的测试仍然是红色或绿色的，但我的网页在web上的外观存在一些问题，我担心错误可能会滚雪球

有人知道这里发生了什么吗？我已经尽我所能在Cloud9IDE中手动键入了他的代码块，因此语法应该是100%正确的。我的背景是Java和C#，这让我想起了编译器错误

1）错误：

需要“测试助手”
类UsersLoginTest

错误1：您需要提供更多详细信息。但是错误跟踪表明，当您第二次使用delete方法调用logout_路径时，出现了一些错误。你能提供你的

sessions\u helper.rb

文件吗

错误2似乎来自

index.html.erb

模板。你能把密码寄出去吗

错误#3:您正试图以

@user

身份登录，但未定义此实例变量。将行

登录为（@user）

更改为：

登录为（@admin）

另外，请注意您的测试

“记住登录”

是错误的，应该是：

test "login with remembering" do
  log_in_as(@user, remember_me: '1')
  assert_not_nil cookies['remember_token']
end
