我在第 9.3.1 章的末尾并在 Hartl 教程中运行 exec 测试，并收到以下失败/错误：

Failures:

     Failure/Error: it { should have_selector('title', text: 'Sign in') }

这是我的代码，我将不胜感激任何建议。

有什么问题？？

您需要更改 users_controller.rb 中的 before_filter 以包含索引：

  before_filter :signed_in_user, only: [:index, :edit, :update]

使用您的代码，您无需登录即可查看索引页面，这就是您的测试在标题中看不到“登录”文本的原因。
