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.

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...

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...

这本书看的时间非常长, 断断续续有3个星期了吧, 不错的书, 至少对我来说是这样, 因为我现在就碰到了书中列出的种种问题:对已有的没有完善的单元测试的核心系统进行重构.为了保证少出乱子, 不出乱子, 我必须小心的对超大类, 巨型方法采用各种重构手段进行修改, 没有单元测试作保...

TDD, 短小精湛，好读

介绍了很有用的`characterization tests` and `Link seams`

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.” :)
