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

评分☆☆☆☆☆

一两个月前看到了这本书，那时候正对编写高质量的代码很感兴趣，于是借来读。这一个月断断续续的读完，实际上读书的时间仅有10天左右的业余时间。读的很浅，但也有小小的收获。这本书讲解如何在不漂亮的旧代码下写漂亮的新代码，依照先有测试后有功能的思想，作者全书都围绕...

《修改代码的艺术》看完了这本书很薄，但是看起来还是很吃力，里面介绍了很多重构的知识，而且有很多c++的内容，有的地方也是似懂非懂的，如果了解设计模式和重构，就会轻松很多，可能艺术这东西，本身就不容易懂吧。里面对单元测试的依赖性很强，其实还是一本不错的书，你完...

14h:05 in 6 days。我的“重构三部曲”之三，（另外两本是《重构》，《从重构到模式》，这三本书让我对代码的理解有重生之感。大部分书都是教你怎么从0开始写好代码，但是现实是经常从接手已有的项目开始，所以这三本就很有价值。）这本书压箱底8，9年了，前些年有次囫囵吞枣看...

如果你想重构,重要的前提就是有强力的测试.哪怕你有自动化重构工具在手. 如果你想对既有代码进行测试,你就必须先重构,因为代码根本就没有办法在测试工具中实例化. …… 新写的代码大多是可以先进行测试,然后再挂接到原有代码中.而对付遗留的代码,我们则需要一点点地把代码抠出...

TDD, 短小精湛，好读

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.” :)
