When you’re working in TDD you’d like your cycles to be short and fairly regular. Let’s look at that today.
Ask participants: What are three things you already know about TDD? Tell them to the person sitting next to you. Bonus: also tell them one thing you want to learn about TDD.
Bring up an example cyber-dojo screenshot with some traffic lights. Show a TDD cycle. Explain you would like them to be short and fairly regular.
Pick an exercise, one that is not too complicated and you can fit several TDD cycles into 35 minutes. For example Closest to Zero. Ask them to work on it using TDD.
If you’ve previously done a ‘test list’ learning hour on this kata you could remind them of it and distribute the list you made that time. Otherwise, remind them to make their own test list.
Review the code and TDD cycles. A tool like cyber-dojo makes test cycles visible, but you can also use the local history in your IDE, or git history.
