Get more out of your legacy systems: more performance, functionality, reliability, and manageability
Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts.
In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control.
The topics covered include
Understanding the mechanics of software change: adding features, fixing bugs, improving design, optimizing performance
Getting legacy code into a test harness
Writing tests that protect you against introducing new problems
Techniques that can be used with any language or platform—with examples in Java, C++, C, and C#
Accurately identifying where code changes need to be made
Coping with legacy systems that aren't object-oriented
Handling applications that don't seem to have any structure
This book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes.

读后感
作为一个程序员，获取知识是让我不断前进的动力，而读书是我获取知识的一条重要途径。在这个“经典”、“必读”过剩的年代里，大多数的书都仅仅扮演着传播知识的角色，真正改变自己对某些问题看法的书其实少之有少。限于读书时的眼界和能力，在我列表中，让我拍案惊奇的书只有...
评分当软件系统的规模随着时间不断增长时，我们怎么构建和维护它？面对别人写好的大量的代码基，如何进行后续的可持续开发？TDD，单元测试，重构，设计模式这些看上去很美的技术，是如何应用的？ 毫无疑问，这本书里不可能提供上诉问题的所有答案，但是它至...
评分Java重构的必读书，非常实用，但有的时候我想，Java代码的重构如此复杂，是否说明面向对象的设计思路在很多场合并不适用呢？比如很多服务端的逻辑本身是典型的函数转换，如果使用FP范型开发会简单的多。 推而广之，如果一种技术在大多数程序员手里都越用越复杂，以至于需要专家...
评分很好的实战经验，快来取道。在最近的开发项目中经常想起本书讲解的一些技术，受益匪浅。虽然我并不是 working on legacy code ，但是项目代码从无到有到完善也是经历几个阶段的，在不断演化，不断修正。另一方面，一边写单元测试，也参考了本书。 以前以为测试只是为了保...

绝对好书。适合岁数大的人。年轻人好冲动，动不动就重构，推到重来。岁数大了没那精力了，改吧改吧能凑和就行了。。。此规则同样适合 正文氵台 现象。
评分不只是TDD测试而已，设计的理念也在点滴中渗透，不知不觉就从头看到尾了，都是我们经常工作中遇到的问题。 作者行文流畅，偶尔还写上一两句非常quotable的俏皮话。例如讲到decorator时，他说“Navigating through code that contains decorators that decorate other decorators is a lot like peeling away the layers of an onion. It is necessary work, but it does make your eyes water.” :)
评分被逼的，淫僧啊。。。
评分难得的好书，谁读谁知道
评分介绍了很有用的`characterization tests` and `Link seams`
