Nice web slides navigation (and useful information!)



Workflows of Refactoring  by Martin Fowler


TDD "red-green-refactor cycle"

• Red: Add a Test
• Green: Make it work: 
• Refactor: Make it Clean

The metaphor of Two Hats ("You can only wear one hat at a time")

• Adding code
• Refactoring

Litter-Pickup Refactoring

This is often referred to as the boy-scout rule.
Always leave the code better than when you found it.

Comprehension Refactoring

clear code, like clear writing, is hard to do



"People should be always on the look-out for substandard code. Often as a team learns, code written a few months ago can now seem lacking, and should be fixed."

Preparatory Refactoring

A common analogy for this is prep work before painting.

Planned Refactoring

schedule refactoring as part of their planned work,

Long-Term Refactoring

large-scale restructuring
