Spring Boot application that showcases the component-test-framework for component testing.
The framework is available on Maven Central. View usage here:
https://github.com/lydtechconsulting/component-test-framework
This example application uses Kafka as the broker, Postgres as the database, and uses the Transactional Outbox pattern with Debezium (Kafka Connect) for Change Data Capture (CDC) to publish outbound events.
The service calls out to a third party service via REST. This is represented by a standalone wiremock in the component tests.
The Debezium Postgres source connector configuration is defined in resources/connector/outbox-connector.json.
It includes a Single Message Transform (SMT) that routes the outbox event to the value of the destination field in the outbox event database table.
The component tests treat the application as a black box performing end-to-end testing and proving the deployment and configuration in a local environment.
