Feathers Michael Working Effectively with Legacy Code

Feathers (Object Mentor) presents his approach to making sense out of legacy code, and describes techniques for getting it under test, refactoring it, and adding features. He discusses instantiating a class in a test harness, adding behavior to existing classes, reasoning forward about effects, controlling the size of classes, and several dependencThe 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 structureThis book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes.
