My notes on the video series "London vs Chicago TDD styles" by Uncle Bob And Sandro Mancuso

The git repo of the kata is here: https://github.com/sandromancuso/cleancoders_openchat/

The "starting-point" branch is where both implementations began: https://github.com/sandromancuso/cleancoders_openchat/tree/starting-point

• The 🇬🇧 "openchat-outside-in" branch captures the tomato by tomato history of the London approach.
• The 🇺🇸 "openchat-unclebob" branch captures the tomato by tomato history of the Chicago approach.

What I like about Sandro's style 👍

Takeaways from TDD and Software Design

video

• TDD by its own CANNOT leads to good design, obviously
• TDD as a mechanism to help us to learn more about good design
• Software is "Soft" just because it can be changed, it is not meant to be settled in the stone
• Test-first programming can help the team to reduce defects but it will not lead to good design

Code qualities
