Cyber Dojo for teaching TDD

Posted on June 10, 2014 by Eric Lefevre-Ardant

I’ve been teaching “Agile Projects” (yes, the title does feel a bit strange) to undergraduate students for a few years, and I’ve always took that opportunity to spend half a day on TDD. That meant me demo’ing a test-first implementation … Continue reading →

Why aren’t there more Agile luminaries developing and selling software?

Posted on September 10, 2010 by Eric Lefevre-Ardant

Posted on June 4, 2010 by Eric Lefevre-Ardant

Robert “Uncle Bob” Martin has just blogged on the differences in TDD styles using Clojure, as compared to more traditional languages such as Java. Though I am a Clojure-newbie, I mostly disagree with his conclusions. His main point is that, … Continue reading →
