几年前，我在一个没有单元测试可言的大型代码库中工作。

代码中隐藏了一个执行一些日历计算的方法。它有点坏了，由于一些不幸的情况，不得不以一种非常笨拙的方式处理夏令时。

我们不得不修了几次，每一次，我们都会在几个月后发现一些东西坏了。

在花了一整天的时间修复和分析之后，我把代码放到了源代码控制中，并附上了这样的评论:

// this code was written after a version trying to do {this} failed because of {reason},
// previously we were doing {this} which failed because of {reason}. This is 
// now written {this} way so that {lots of reasons here}. If you want to touch
// this code, please make sure that it produces the right answers when tested with:
//
// {some sort of unit test}

最终，我的团队被外包了。有时我想知道这段代码发生了什么:)

    /* Mark: If there's one thing you learn from this code, it is this...
   Never, ever fly Air France.  Their customer service is absolutely
   the worst.  I've never heard the words "That's not my problem" as 
   many times as I have from their staff -- It should, without doubt
   be their corporate motto if it isn't already.  Don't bother giving 
   them business because you're just a pain in their side and they
   will be sure to let you know the first time you speak to them.

   If you ever want to make me happy just tell me that you, too, will
   never fly Air France again either (in spite of their excellent
   cuisine). 

   Update by oej: The merger with KLM has transferred this
   behaviour to KLM as well. 
   Don't bother giving them business either...

   Only if you want to travel randomly without luggage, you
   might pick either of them.
