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.

讀後感

評分

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...  

評分

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...  

評分

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...  

評分

买这本书的原因一是这本书确实是一本关于修改老代码的经典,二来翻译者是中国地区 InfoQ 的主编。 但是入手看了大概到100多页之后实在是忍不住要上来吐槽一下。 首先是翻译的通畅性,应该说是比较烂的水准<del>只能说是将将达到合格的水准,</del>这个可能是个人的偏见。但是...  

評分

我发现很多网页里卓越的报价常常比当当的高,可是实际情况是点击链接后卓越比当当低! 比如这本书实际报价:卓越是46.5,当当是46.6 不知道是不是最近卓越大范围调整了价格?! 顺便说一下,在csdn读书频道上也有类似情况。

絕對好書。適閤歲數大的人。年輕人好衝動,動不動就重構,推到重來。歲數大瞭沒那精力瞭,改吧改吧能湊和就行瞭。。。此規則同樣適閤 正文氵颱 現象。
