Last month Jetbrains released an early access preview of their new AI tool Junie. Junie is an agent. This means that we can give it a goal, it will devise a plan, and then execute tasks autonomously. It can even change its behaviour based on how things are going.

In this first look at Junie I’m going to tell it the rules of Test Driven Development and see how well it can follow the process. As in the last episode, I will write the tests, and ask Junie to write the implementation code.

This one is really, really interesting.
