在我对 Hartl 教程的第 9.2 节中的rspec 测试进行最后一次更改之前，所有测试都运行良好。那时我的 user_pages_spec.rb 和 application_pages_spec.rb 中的所有相关测试都失败了。
不过，我已经检查了该站点，并且故障并没有出现在现实生活中——所以我认为这是测试套件试图模拟用户的方式的问题——这是有道理的，因为这就是我所做的改变。
需要注意的一件事 - 我已经对 Hartl 教程进行了一些调整，但大多数都是装饰性的或次要的 - 这里唯一可能重要的是我使用用户名而不是电子邮件进行登录和查找。
完整文件如下 - 非常感谢任何帮助，因为我已经把头撞在墙上几个小时了，而且它变得非常令人沮丧。
