Testing Java Lox with jUnit

If you are going through a book like Crafting Interpreters and just input the code from the book and run it, maybe you don’t need tests. I would also argue you are probably not going to learn the material very well. Writing tests on its own will help build your understanding of the code the book is explaining to you, but the real point of adding unit tests is to support doing the exercises. I am not going to bother explaining the value of unit tests in general or test driven development, but I think it’s worth highlighting that the value of unit tests is particularly clear when you are refactoring and extending an existing codebase (which is basically what you are doing when you implement the features from the exercises).

“Everything starts with a class in Java. Stick that in a text file, and go get your IDE or Makefile or whatever set up. I’ll be right here when you’re ready. Good? OK!” - Crafting Interpreters, 4.1 - The Interpreter Framework

“Or Whatever Setup”

Ok so we’re reading Crafting Interpreters, and the book wants to write its examples in Java. There are a lot of ways you could go about building and executing a Java project. Since I am a masochist who refuses to let an IDE set up my project for me, I’ll need to choose that setup for myself.
