Testing focus boosts XP
The abysmal quality of software has led to Extreme Programming (XP), a discipline for developing software that requires test-driven design, continuous testing and acceptance of constant change. As one application services provider (ASP) delivering complex demand chain management solutions has found, XP has enabled rapid development of quality software. The XP movement, which Kent Beck kicked off with a paper on Smalltalk programming, emphasizes testing that helps to bring new developers up to speed rapidly. It also aids developers when they refactor, or change, code. Every programmer writing code has to refactor existing code to streamline it, and continuous testing gives developers confidence that their refactoring works.
