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 dependency-breaking techniques. The short code examples are written in Java, C++, and C. Annotation 穢2004 Book News, Inc., Portland, OR (booknews.com)
