Introduction

This is a sample application showing how to use Testcontainers and Redpanda for writing integration tests in a Spring Boot Kafka application.

It uses Redpanda Testcontainers module which enables straightforward integration and provides additional developer experience enhancements for better integration tests. For more information please check out the article about this sample application.

Run the tests

Clone the project and run Maven tests:

./mvnw test

A bit more details

The environment for the integration tests is created by Testcontainers, and to create a Redpanda instance for your application to work with all you need is to instantiate and start a Testcontainers Redpanda class:

RedpandaContainer kafka = new RedpandaContainer("docker.redpanda.com/vectorized/redpanda:v22.2.1");
kafka.start();

You can see how it's implemented and how the configuration about Redpanda location (host/port) is passed to the Spring Boot app in the code.
