First International Test Driven Development took place on July 10th.

In this series, I will include every talk together with my notes and further reading.

Hopefully, a lot of readers will watch and rewatch the talks, as they are worth several reviews.

Let's continue...

Want More Value Faster? Take Many More Much Smaller Steps - GeePaw Hill

Bio

We all know and love GeePaw and his inimitable style of "Helping Geeks Produce for Over 40 Years."

TL;DR: Baby steps are the best way to go from one place to the next one.

Talk

My Personal notes

• TDD is like cooking. We use too much rice and too little garlic.
• Take many more (and) smaller steps to change faster.
• Old demonstrations are ridiculous tiny compared with today's.
• Single threaded construction
• Target didn't change.
• Today, we work on gigantic apps with changing requirements.
• We should divide and conquer (decompose) more.
• Take baby steps between activated states.
• We should fix maximum duration to keep steps "baby" (< 1 hour).
• The most efficient path is the one with smaller steps.
• Even if some steps don't produce user value or diverge.
• They just can't get worse.
• The Walking Skeleton is the working app.
• Software isn't plain geometry.
• Changeability costs less than rework avoidance.
• We seldom can go from one point to other in a straight line.
• Problems in software are not polynomial. They get NP Hard.
• During baby steps, we should not be interrupted. (or we will need to start over)
• Programming is thinking. It is not related to typing.
• on TDD we have automated consequence detection, fast context switching and executable documentation.
• The worse bugs in the world are the ones you had no idea you just shipped.
• We should maximize knowledge sharing to increase changeability.
• The only requirement is for steps to be as small as possible.
• TDD is not as simple as Red, Green, Refactor. It takes time to master.
• We need to collaborate by mobbing, pairing and swarming.
• They are not natural skills.

We live in a world of misconceptions of thinking knowing syntax is at the heart of the problems. Lots of people believe there's a technical solution to every problem and that it would be best for all of us to sit in dark rooms working quietly by ourselves.
