Quarkus - Integration Tests

(1) Background

This Quarkus project uses Testcontainers with the Docker Compose Module for setting up an integration-test environment which contains:

Postgres DB
Kafka Broker
Kafka Zookeeper
Quarkus application

I'm using Mavens integration-test and verify phase to run my integration-tests against the docker-compose environment started by testcontainers. The test-classes are normal JUnit5 tests without the Quarkus annotations @QuarkusTest and @NativeImageTest.

This mechanism addresses an integration-test scenario where all real world components (postgres, kafka, etc. but no mocks or H2 dbs) and the application itself are in place for being tested from outside via REST calls. Without the need to deploy the whole stuff to your target cloud environment.

(2) run locally

(2.1) run integration-tests in JVM mode

Change inside docker-compose.yml the dockerfile property of the app service to Dockerfile.jvm and use the jvm command
Maven verfiy
```
mvn verify
```

(2.2) run integration-tests in native mode

Change inside docker-compose.yml the dockerfile property of the app service to Dockerfile.native and use the native command
Maven verfiy
```
mvn verify -Pnative
```

(3) run on Jenkins

mvn verify can be used at any CI build-pipeline too.

(4) other stuff

I'm using the shell-script wait-for-it.sh (https://github.com/jlordiales/wait-for-it) to wait with the Quarkus application start until all dependent services are up and running.
