The subject of this article is the String Calculator proposed by Roy Osherove. The Kata is done in C# uses Visual Studio 2012, JetBrains Resharper 7 and NCrunch.
But what is a TDD Kata? It is an implementation exercise starting with unit tests and leveraging refactoring that you practice daily for around 15 to 30 minutes.
The goal of this video is to present one of those session I did recently of this practice that I really find interesting.
The video was also published on Tech Head Brothers, my french portal about .NET.
