结论
调试不容易，但这是我们的过错，因为是我们制造了
bug
。对所有程序员来说，高效调试
都是必不可少的技能。
思考题
1.
评估你在调试代码上花的时间。这里面应该包括所有没有编写新代码的活动。
2.
你是花更多的时间调试新编写的代码，还是对现有代码进行调整？
3.
单元测试的存在是否会改变你花在调试上的时间或调试方式？
4.
以编写不含
bug
的软件为目标现实吗？这是可以实现的吗？什么时候需要不包含
bug
的
软件？是什么决定了产品中可以接受的
bug
数量？

立刻行动
下次遇到
bug
时，尝试用一种更有条理的方法来进行分析。如何使用捕获、二分法和
更强大的工具来更有效地跟踪错误？
（调）bug
如果调试程序是移
除bug的过程……
那么编写程序就是把
bug放进来的过程

我不是在找bug
比那更糟
代码里的bug比螃蟹都大
