# Kotlin Architecture Tests with Konture: Practical Guide How to create structural rules that enforce module boundaries in Kotlin projects - **Source:** [ProAndroidDev - Medium](https://brifing.si/source/d9553fa9-7b72-4b9b-bc73-c6bf9a40dd5f) - **Published:** 2026-07-17 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/41314e29-2cf3-454b-a3fa-f9270d4807c8 ## Importance of Architecture Tests Architecture tests are crucial for maintaining modular structure in Kotlin projects. The Konture library automatically verifies dependency rules between project modules, helping preserve clean architecture. It's particularly valuable for growing projects that need clear boundaries. ## Test Module Setup Creating a dedicated architecture-test module is a best practice. This approach provides project-wide visibility without adding test dependencies to production code. You can easily configure the konture-test module using Gradle Kotlin DSL. ## Basic Dependency Rule Preventing horizontal dependencies between feature modules is a fundamental architectural rule. For example, a feature implementation module shouldn't depend on another feature implementation module. Konture makes it simple to define such rules. ## Cycle Detection Circular dependencies in module graphs increase build times and weaken boundaries. Konture's assertNoCycles() method helps proactively detect this issue. It's an essential check for multi-module projects. ## Domain Layer Protection You can define specific rules to keep the domain layer clean. For instance, ensuring domain classes only depend on domain packages and standard libraries helps maintain architectural integrity. ## Framework Import Restrictions Konture allows creating rules to prevent framework dependencies (like Spring or Android) from leaking into the domain layer. These specific controls help maintain clear architectural layers. ## Repository Contracts Ensuring repositories in the domain layer remain interfaces is important for layered architecture. Konture can automatically verify whether repository classes are properly defined as interfaces. ## Package-Based Rules Konture's advanced package matching features let you create rules for specific package prefixes. This is particularly useful for KMP projects with different policies for commonMain, androidMain, and iosMain. ## Custom Assertions The scopeFromPackage method enables custom validations for specific packages, allowing fine-grained architectural rules tailored to your project's unique needs. ## CI Integration Architecture tests can be easily integrated into your CI/CD pipeline. Using a separate module allows running these tests with a single Gradle task, making them part of your build process. ## Rule Development Strategy Start with simple rules already agreed upon by the team, then add more specific checks as the project grows. Each rule should serve a concrete purpose in maintaining your architecture. ## Benefits of Architecture Tests Konture-powered architecture tests prevent complexity as projects scale. By enforcing clear boundaries, they reduce maintenance costs and ensure team adherence to architectural decisions. It's a critical investment for long-term project health. ## Sources covering this story - https://proandroiddev.com/kotlin-architecture-tests-with-konture-a-practical-guide-part-3-3-1f36ebe685db?source=rss----c72404660798---4 — --- _Summary written by Brifing from the original reporting.
