I was listening to another good Hanselminuets podcast - Understanding BDD and NSpec with Matt Florence and Amir Rajan.

There is a huge number of books about TDD. Those books usually
concentrate on using test for units of work. Units of work are
understood in many different ways, usually it means a class. So the
books say: write a lot of tests, make code in such a way the...

Imagine an ant working at the top of a mountain. Next to it, there’s a
sluice of melt water running and, at that moment, the ant removes a tiny

I’ve found this question while going over my old StackOverflow answers:I'm
using reflection to loop through a Type's properties and set certain
types to their default. Now, I could do a switch on the type and set the
default(Type) explicitly, but I'd...

I’ve been teaching and practicing agile for several years and there
is definitely a problem with TDD: People find it very difficult to use.

Last week I conducted yet another code review. While looking at the code I’ve noticed a lot of lines similar to If(x != null) and if(y < 0) all
over the code. These lines were not “business related” but were put in
the code to make sure that proper...

To achieve an impeccable system design, write a failing test first, a simple implementation to pass the test, refactor and repeat. Sounds easy, right? Then why is it not so easy to get developers to adopt this technique on a regular, or better yet,...
