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.<p>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.<p>This one is really, really interesting.
