From my series on developing the online version of JitterTed's TDD Game (see https://tdd.cards for the physical game).
Tech Stack: Java with Spring Boot, Spring MVC and (eventually HTMX), JUnit testing via TDD, and architected according to Testable (Hexagonal) Architecture principles.
This is Episode #1, where I try and resuscitate the years-old code, and then start over with a new codebase, planning on scavenging old code as needed.
You can find the code on GitHub at: https://github.com/jitterted/tdd-game and look through the commits to see the progress made in the videos. You can also find me on Twitter: @jitterted / jitterted
These videos are from my live coding that you can find on Twitch: https://JitterTed.Stream
