Over the years I have come to describe Test Driven Development in terms of three simple rules. They are:
1. You are not allowed to write any production code unless it is to make a failing unit test pass.
2. You are not allowed to write any more of a unit test than is sufficient to fail; and compilation failures are failures.
3. You are not allowed to write any more production code than is sufficient to pass the one failing unit test.
You must begin by writing a unit test for the functionality …

The thing I like about the pattern form is that it gives you a way to talk about the motivation for what you are doing. So there is a lot of Java style books, and good ones, out there people with lots of experience, people who’ve thought carefully about how to program, but when I read them what I hear is a set of commandments, “Name variables like this, arrange your code like that, etc” and all those are good things to do in certain circumstances, but what doesn’t ever …

I have been distraught at the level of dogmatism, bigotry, contempt, or just plain ignorance that I witness in the agile world. I am not blaming the topnotch agilistas, though they sometimes, and just for effect in writings and presentations, reduce their messages to their essential bones, to the slogan level, and they omit the context—both source and applicability.
As agility is crossing the chasm, however—as you can see if you attend any big software synod such as SD East or West or OOPSLA (Object-Oriented Programming, Systems, Languages, and Applications)—many more …

Excerpt from: Stanley Bing, “The 0% Solution”, Fortune, Europe Edition, December 18, 2006
News comes from the Department of Labor that productivity growth in nonfarm business in the U.S. hit a critical number in the third quarter. That number was zero, as in naught, as in nothing, no growth at all, not even something you could round up to a minuscule decimal of some kind. [...]
Let’s look at what forces are coming together to suppress productivity growth, to see if we can augment them in some way. [...]
Second, I’m thinking that …
