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?

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

How many things can… Continue reading Combining TDD/BDD with DDD

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
