TDD – From the Inside Out or the Outside In?

Often the hardest part of programming is knowing where to start. With test-driven development the right place to begin is with a test, but when faced with a blank page, it can be daunting. Is it best to start with the detail of what you are building, and let the architecture form organically using an… Continue reading TDD – From the Inside Out or the Outside In?

Vertical vs Horizontal Approaches

In the light of delivering outcomes, we should consider the respective merits of horizontal and vertical approaches.  The more common (and not necessarily incorrect) approach is to slice a problem horizontally and build layers to a stack based on objectives with clear left and right parameters.  This not meant to imply that there is a… Continue reading Vertical vs Horizontal Approaches

Software developers often make fun of this our tendency to suffix everything with “DD”. I have three points to make about this:… Continue reading xDD: An Overview

If you are unsure of their exact meanings, why wouldn’t you believe that TDD is in opposition to BDD and DDD? I mean, they all mean “Hmmhmm Driven Design/Development”. How many things can… Continue reading Combining TDD/BDD with DDD

Summary of The Mythical Man-month

Chapter 1 “The Tar Pit” Pg. 4 In software development, no one thing seems to cause the difficulty, but the accumulation of simultaneous and interacting factors brings slower and slower motion. Pg. 5 Developing a professional system is 9 times the cost and time of an amateur development of the same system. Pg. 7-9 Joys… Continue reading Summary of The Mythical Man-month


The Solution to Technical Debt

From By Henrik Kniberg (related article: Good and Bad Technical Debt – and how TDD helps) (Translations: Russian) Are you in a software development team, trying to be agile? Next time the team gets together, ask: How do we feel about the quality of our code? Everyone rates it on a scale of 1-5, where 5… Continue reading The Solution to Technical Debt
