TDD Conference 2021 - TDD All The Things - Liz Keogh

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...

TL;DR: Amplify your possitiveness!


My Personal notes

  • BDD suggests we should start methods with 'should' instead of 'test'.
  • Nowadays we have annotations on tests.
  • BDD forces us to think about behaviour.
  • TDD cycle as behaviour: Test = Describe Behaviour, Pass = Change Behaviour, Refactor = Amplify the positives
  • The sandwich methodology: Say something good, then something bad, and after that something good again.
  • The sandwich done well: describe what you want and don't let people write their own code.
  • Try to find psychological safety.
  • Novice people can write tests by copying existing ones.
  • Experienced Beginners can get TDD working from scratch.
  • Practitioners write tests before the code.
  • Knowledgeable Practitioners teach TDD to others.
  • When refactoring, aim for better, not perfect.
  • When refactoring people, we should play to our strengths and be forgiving.
  • In complexity, tests and descriptions of behaviour are just examples of what might happen.
