用户注册测试在M.Hartl的Rails教程中失败

我一直在关注M. Hartl的Rails教程，我遇到了一个问题。 当我从第10章开始，所有代码都正常工作，我的测试套件正在通过。 在第11章中，我到目前为止所做的就是创建一个新的分支。 我的文件都没有被修改过。 但不知何故，我的测试套件现在失败了。 更奇怪的是，它不会100％失败。 有时它会通过，但大部分时间都会失败（如果我一次又一次地运行它而不更改任何代码）。 相关代码和错误消息如下。 任何帮助将非常感激。 谢谢

错误：

Answer 1

您的代码缺少清单10.29中定义的setup方法。

Answer 2

在挂钩处理ActionMailer的所有规范之前，尝试添加以下内容

 before { ActionMailer::Base.deliveries = [] } 

它看起来像其他规格也发送电子邮件。 结果因规格的任意顺序而异。
