According to Wikipedia, Calisthenics are a form of exercise consisting of a variety of simple, often rhythmical, movements, generally without using equipment or apparatus. Since programming without Visual Studio is going to be a bit challenging you can define Object Calisthenics as a programming exercise that uses simple rules to motivate you to take an object-oriented approach to programming. As an experienced developer practicing Test Driven Development I was a bit sceptical of whether I really needed those rules to be a better programmer. But to my surprise those little rules really reinforced my beliefs about building high-quality software using the principles of object-orientation, SOLID and Clean Code. So what are those rules? I won’t tell you…yet. Just come to my session and I’ll let you in on my secrets….
