ArchUnit
Java architecture test library for asserting packaging, layering, cyclic-dependency and naming rules in plain JUnit tests.
Our Verdict
The cleanest way to turn architecture decisions into executable guardrails on the JVM.
Pros
- Enforces layering and package rules as real JUnit tests
- Catches cyclic dependencies before they rot the codebase
- Readable fluent DSL, reviewable alongside code
- No runtime overhead, pure static bytecode analysis
Cons
- Java/JVM only, no Kotlin-specific idioms
- Rules can get verbose for nuanced architectures
- Steep ramp for teams new to architecture testing
- Slow on very large monorepos without filtering
When to Use ArchUnit
Good fit if you need
- Enforce layer dependencies in hexagonal architecture
- Prevent cyclic package dependencies in Java monorepo
- Assert naming conventions for services and repositories
- Fail CI builds when architecture rules are violated
