测试突然出错。任何人看到这个错误？

Question

Ruby 1.8.6，Rails 2.2.2，OS X老虎

我的测试::单元测试开始返回下面的错误。相关行似乎是：

`load_missing_constant': 
    Expected /Users/ethan/project/mtc/webcalendars/app/models/calendar.rb 
    to define Calendar (LoadError) 

提到的文件，calendar.rb看起来不错。我找不到任何错误。我尝试删除日历模型的单元和功能测试文件，但这对错误没有影响。

在浏览器中，应用程序似乎正常工作。

任何见解？任何人都可以提出一种方法来隔离问题吗？

更长的摘录：

Answer 1

阮经天， 我已经看到了这个唯一的一次，当我在一个文件中定义多个类。我不会自己使用test：unit，但是在定义Calendar之前可能定义了另一个类？

希望有所帮助。
