Solid Foundation For Software Refactoring (Score 3, Insightful)

To get to know refactoring, I can refer to http://www.refactoring.com (by Martin Fowler).

For those interested in the value of refactoring (whether it's merely a buzzword), I can refer to a research project of ours, at http://win-www.uia.ac.be/u/lore/refactoringProject

By the way: since the article does not go into behaviour-preserving restructuring of JUnit, they shouldn't mention 'refactoring' in the title.
