dc3-common-test is the shared test-support module of the IoT DC3 platform. It provides reusable contract tests, test harnesses, and Testcontainers definitions so individual modules can write integration tests without re-deriving the same fixtures.

Module Information

Group ID: io.github.pnoker
Artifact ID: dc3-common-test
Version: 2026.5.22

Key Components

Area	Components
Contract tests	`SecretFieldContractTest`, `EnumContractTest`
Test support	`RabbitTestHarness`, `JsonAssertions`, `FixedClockConfig`, `GrpcInProcessExtension`
Testcontainers	`PgTimescaleContainer`, `RabbitContainer`, `MqttContainer`

Dependencies

spring-boot-starter-test, reactor-test, spring-rabbit-test, grpc-testing

Usage

Add as a test-scoped dependency. Integration tests requiring real infrastructure use the Testcontainers helpers (PostgreSQL + TimescaleDB, RabbitMQ, MQTT), which need a running container runtime (podman).

Build Instructions

mvn -s ../../.mvn/settings.xml clean package

dc3-e2e — backend end-to-end suite built on these helpers
