Introduction Programmers are typically taught to think of the type system in languages (particularly object-oriented languages) as being a way to express

“Specification by Example” is a particular implementation strategy of Behavior-Driven Development. The central justification, as far as I can tell, is expressed

Introduction What is “agile” software development? Well, more than anything, it’s definitely not waterfall. At least in the case in this age

When you first get introduced to the idea of test driven development, it may seem strange that tests become such a central
