Rails教程3第9.1章: Rspec测试失败时应该通过

Question

我是一个rails新手，并且一直在研究Michael的令人敬畏的Rails 3教程，并取得了巨大的成功。到目前为止，我所有的测试都在他们应该做的时候起作用(根据书)。然而，我在第9章开头，并且正在通过rspec测试--也就是说，浏览器中的功能是完美的。

我检查了所有的东西，甚至查看了示例应用程序的github回购，但仍然无法找到如何治愈我的rspec问题。任何帮助都是非常感谢的。

解决了更新！

谢谢各位的评论。最后，我做了几件事情，让考试通过了：

• 重新启动的轨道
• 继续跟踪这本书，直到9.2.1年底

做完这两件事之后，测试套件如预期的那样变成了绿色。希望这能帮助那些陷入同样困境的人。
