Exploring Extreme Programming
Working Effectively with Legacy Code, Michael Feathers. Prentice Hall, 2004. Michael has distilled a lot of knowledge about how to safely improve code when you lack the safety net of tests. For example, there are places where you’ll take smaller Continue reading Review – Working Effectively with Legacy Code
Sven Gorts has introduced Refactoring Thumbnails to summarize refactorings. Continue reading Refactoring Thumbnails
Refactorings are often described as transformations that preserve semantics, but they still may require new tests. Continue reading Refactorings Require New Tests
Sometimes it pays to do things twice. Continue reading Scratch Refactoring
When refactorings change the design of a system, they update the tests just enough to accommodate the revision. This keeps the tests working, but tests have other roles. To continue to support these roles, you often need to further modify the tests and add new ones. Continue reading The Impact of Refactoring on Tests
“Amazing” is a maze generation program from the book BASIC Computer Games, by David Ahl. (The maze program was created by Jack Hauber). The code is used with permission of David Ahl, www.SwapMeetDave.com. Alan Hensel mentioned using this program as inspiration for Continue reading Refactoring Challenge – The Amazing Maze
Programming in the world of “What If?” Continue reading Subjunctive Programming
The refactoring grid is a toy designed to give you a feel for what refactoring is like, by working in a simple, non-code domain. [Michael Wainer has made game pieces available here: http://www.cs.siu.edu/~wainer/Pieces4RefGame/pieces4RefGame.html ] The Domain There is a grid Continue reading Refactoring Grid
Refactoring: Improving the Design of Existing Code, Martin Fowler et al. Addison-Wesley, 1999. The best printed source on refactoring. Uses Java for the examples. See also the Refactoring home site. (Reviewed Nov., ’02)
Extreme Programming Explored, by William C. Wake. Addison-Wesley, 2001. Foreword by Dave Thomas (The Pragmatic Programmer). This book grew out of the XPlorations series of articles. I wrote them as I was learning XP, and relating it to my own Continue reading Extreme Programming Explored
