TDD Conference 2021 - Want More Value Faster? Take Many More Much Smaller Steps - GeePaw Hill

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


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.


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.
