#EvolutionaryDesign or #DesignUpfront? I believe it’s a bit of both as I always bring in my past experience and have some design in mind before I start to #tdd. I also evolve the design as I learn more about the domain and listen to what my tests are telling me.
Here’s a 2007 discussion between Jim Coplien and Uncle Bob that prompted me to write this: https://youtu.be/KtHQGs3zFAM

Further to my recent discussion about #TestDoubles/ #MockObjects in design, I remember asking this question at a SoCraTes event in Rochegude, France:

"Are method/function expectations an #OOP disease?"

(Or something similar.)

The short answer seemed to be this: it's quite OO, but maybe not a disease. In FP we sometimes contort ourselves to turn complicated custom workflows into straightforward function composition, and it's not always worth the effort.

Further to this idea, whose videos on "evolutionary design without #TestDoubles / #MockObjects" would you endorse? I mean you really like them. You found them compelling and convincing. They don't have to be free.

Our December presenter for the Jersey City Java User Group: @jbrains on how you can acquire #EvolutionaryDesign skills and apply them to your lasting benefit. Discussion will probably ensue. https://www.meetup.com/Jersey-City-Java-User-Group-JC-JUG/events/275046368/ #refactoring #tdd

This is tomorrow (!). You have < 30 hours to RSVP: https://www.meetup.com/Jersey-City-Java-User-Group-JC-JUG/events/274098904/
