A Behavior Perspective on Development

I like to try multiple different approaches to solving a problem to see how they compare.  I might learn something from one approach that I could apply to another.   As an example, I created an alternative approach to calculations with fractions.  The fraction idea comes from J.B. Rainsberger’s class on Test Driven Development. It is a great demonstration of TDD.  

In this example, I’m going to use Gherkin as the specification language for the customer facing behavior For applications where the external behavior and its component parts are specified by the customer and/or stakeholders, having examples in Gherkin can dramatically decrease the communication impedance between the customer and the developer.   PDF is here.
