DC3 Common Test

Overview

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

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 Docker-compatible container runtime.

Build Instructions

mvn -s .mvn/settings.xml -pl dc3-common/dc3-common-test -am package

Testing

This module currently has no module-specific automated tests. Verify generated or production sources by compiling the affected reactor from the repository root:

mvn -s .mvn/settings.xml -q -pl dc3-common/dc3-common-test -am -DskipTests compile
