Recently I had the pleasure of giving a talk at the Canberra Java Users Group on the topic 'Real Developers Don't Need Unit Tests':

"Unit testing, and Test-Driven Development in particular, is a vital but neglected art. Proper TDD don't just test code: your tests are executable requirements that tell the story of your application, clarify your design, document your code and help track your progress. They help you find bugs fast, and fix them with confidence. If Real programmers don't need unit tests, they sure make life easier for the rest of us!"

I've posed the slides for this presentation in this article.
