This is my playground project for implementing an interpreter for the Monkey language. I'm following the Writing an interpreter in Go book, where the Monkey language comes from.
For launching the tests, you can run cargo test as usual.
Personally, I use cargo-nextest as it's faster and provides a shorter output. The command with it is cargo nextest run.
Moreover, as the command is long to write, I use just to easily launch it. With just, simply launch just test.
