Extreme programming

Extreme Programming (XP) is a new method? in or approach to software engineering, formulated by Kent Beck, who wrote the first book on the topic, "Extreme Programming Explained. Embrace Change" (ISBN 0201616416 (amazon.com, search)).

Fundamental for the method are:

• short incremental programming steps
• continuous, often repeated automated regression testing. See JUnit.
• pair programming
• user interaction in the programming team
• fixing all known bugs before adding functionality
• refactoring
