ArchUnit - Unit Testing Architecture and Design

Most projects probably have some kind of documentation of the architecture and code conventions. It's just a question of Where? And are these documentations up to date? Does the code really adhere to these standards? In the field, documentation is all too often "write-only" and bears an only faint resemblance to reality.

Wouldn't it be nice if your architectural and coding rules were checked automatically, as part of your continuous integration build? And if architecture wasn't just an occupation of some distant architect, but rather a team sport for all developers, like in an agile, cross-functional team?

With "ArchUnit" it's possible to code your architectural decisions as plain Java (or Kotlin) rules, using an easy to read fluent API. These rules can check for layered architectures, vertical slices, hexagonal (onion style) architectures, acyclic package dependencies, and for coding conventions like namings, containment of classes in packages and the use of annotations and exceptions. The rules can be checked by any unit testing framework, as for instance JUnit.

You'll see the basics of ArchUnit along with practical tips and tricks, including how to write custom rules. There will be some slides but mostly live coding.

As a technical agile coach and software developer, Thomas Much helps numerous teams to master their methodical and technical challenges. He’s working in projects from enterprise monoliths to e-commerce microservices, most of the time using the Java stack.

He is enthusiastic about people and teams that are eager to learn – learn new things, learn from mistakes that inevitably happen, and learn from each other.
