You can enforce module dependency rules in a multi-module Gradle project by applying ArchUnit tests to validate module boundaries and package isolation. This ensures modules only depend on allowed packages and prevents structural drift.

ArchUnit architecture testing in multi-module projects is used to enforce architectural boundaries, validate domain purity, and detect dependency violations early. It communicates architectural intent through standardized test conventions across modules.

Yes, you need Gradle to set up ArchUnit tests for module isolation. The setup requires configuring Gradle with ArchUnit and the DoNotIncludeTests option to properly validate module dependencies and package structure across modules.

You should run ArchUnit tests to validate package structure when adding new modules, reorganizing packages, or modifying module structure. This ensures changes align with defined architecture and maintains domain purity.

Yes, you can validate domain purity across modules using ArchUnit. The tests enforce package isolation and dependency rules to ensure domain layers remain clean and free from unwanted cross-module dependencies.

The best way to prevent architectural boundary violations is to implement ArchUnit tests that enforce dependency rules and package isolation across modules. This provides a standard ArchitectureTest skeleton to catch violations early.
