Testing in Quarkus

This project applies a complete test strategy to a Quarkus application.

Dev Mode

In dev mode, database container is started automatically, so no manual setup is required.

mvn compile quarkus:dev

Packaging & running

Preparation

For all packages, DB settings must be specified as environment variables before starting the application.

export QUARKUS_DATASOURCE_JDBC_URL=jdbc:postgresql://localhost:5432/todo
export QUARKUS_DATASOURCE_USERNAME=postgres
export QUARKUS_DATASOURCE_PASSWORD=postgres

To start a local database server, the following can be used:

cd src/main/docker/local-setup
docker compose up postgres

Package & run as JAR

mvn package

java -jar target/quarkus-app/quarkus-run.jar

Package & run as über-JAR

mvn package -Dquarkus.package.type=uber-jar

java -jar target/*-runner.jar

Package & run as native image

mvn package -Pnative -Dquarkus.native.container-build=true

./target/quarkus-maven-kotlin-1.0.0-SNAPSHOT-runner 

Package & run native build in Docker container

In src/main/docker/local-setup/docker-compose.yml a Docker Compose file is provided to run the native build in a container.

This also starts a Postgres container. The native image must be build beforehand via Maven.

mvn package -Pnative -Dquarkus.native.container-build=true

docker compose -f src/main/docker/local-setup/docker-compose.yml build
docker compose -f src/main/docker/local-setup/docker-compose.yml up
