Test Driven Development

There are a couple of interesting articles on Test Driven Development at Informit. They are http://www.informit.com/articles/article.asp?p=462520 and http://www.informit.com/articles/article.asp?p=463938&rl=1

To get a flavour the intro to Part one is:

"If you’re a professional software tester, or you work in quality assurance, I consider you to be (like me) a "conventional software tester." Conventional software testers are often asked for opinions and expertise on a myriad of testing-related questions. One new area of thought in software development is test-driven development (TDD). Because it contains the word test, TDD is a topic on which conventional software testers are increasingly asked to weigh in. But since TDD is a programmer-testing activity, conventional software testers often find that they’re inadequately prepared to deal with TDD.

As a curious software tester, I wanted to learn more about test-driven development first-hand. I began learning about TDD through my typical process of inquiry:

1. Read literature about the subject to gain an overall understanding.
2. Explore by working closely with practitioners to gain more comprehension.
3. Immerse myself in the subject by learning from an expert and through practicing on my own.
4. Spend time reflecting on my experiences.

This series of articles describes some highlights from this process. In this article, I share my experience learning test-driven development from an expert programmer. In part 2, I share my experience, applying what I learned by practicing test-driven development myself. In part 3, I share some of my reflective thoughts on what I learned."
