What this system is

Behavioural changes

Migrate event bus from Guava to Spring's event system

The application's event bus implementation has been replaced. The previous Guava-based \DomainEventBus\ and \GuavaConfiguration\ have been removed and replaced with a new \EventBus\ interface and a \SpringEventBus\ implementation that leverages Spring's \ApplicationEventPublisher\. This change also introduces a custom \@CommandListener\ annotation to replace Guava's \@Subscribe\ annotation, updating all command handlers across the product, search, shop, and CDN services to use the new Spring-based event handling mechanism.

Test coverage

Added tests for product domain, services, and infrastructure

Added new test coverage for the product module, including acceptance tests for the product aggregate, unit tests for the domain entity and product number, and unit tests for the CDN, search index, and shop services. Additionally, tests were added for the Spring command bus, event bus, and Spring context startup.

Dependencies

Upgrade Spring Boot and Kotlin dependencies

The project's build configuration has been updated to use Spring Boot version 2.0.3.RELEASE and Kotlin version 1.2.51. Additionally, the Guava library has been removed from the dependencies, and the Spring Boot test starter has been added for testing purposes.

Score

  • CAI 61 → 54 (-6.5)
  • Rubric changed (rubric-2026.08.18 → rubric-2026.09.15) — scores are not directly comparable.

Resolved (8)

  • Coverage not included — suite not readable by the collector
  • Dependency hygiene not measured — dependency manifest found but not parsed for hygiene
  • No exposed public API
  • Test reliability not included
  • early-stage repository — too few commits for a meaningful bus factor
  • early-stage repository — too little history to judge knowledge freshness
  • git history depth insufficient
  • git history depth insufficient

New (5)

  • Dependency hygiene PARTLY measured — Maven/Gradle declarations read, no dependency graph resolved
  • Documentation: no installation or build instructions (README.md)
  • Documentation: no usage examples (README.md)
  • High interface indirection
  • No dependency advisory monitoring

Survey your own repository

bringmeister/ddd-with-kotlin was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.

About this page

  • The score is its most recent published measurement, taken on 21 September 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit e1765b0c3cc871f63aea99677f33c90221952319 — the exact code this score is about.
  • Scored under rubric-2026.09.15 — the same rubric and the same method as every other entry in this index.
  • Measured by watchdog.canine.dev using codehealth-analyzer preprod-28e75b8e3254.
