Test with various databases

MySQL

The simplest way to test with MySQL is to use the official MySQL docker image.

Start MySQL:

docker run --name mysql -e MYSQL_DATABASE=keycloak -e MYSQL_USER=keycloak -e MYSQL_PASSWORD=keycloak -e MYSQL_ROOT_PASSWORD=keycloak -d mysql

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:mysql://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' mysql`/keycloak -Dkeycloak.connectionsJpa.driver=com.mysql.jdbc.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop MySQl:

docker rm -f mysql

PostgreSQL

The simplest way to test with PostgreSQL is to use the official PostgreSQL docker image.

Start PostgreSQL:

docker run --name postgres -e POSTGRES_DATABASE=keycloak -e POSTGRES_USER=keycloak -e POSTGRES_PASSWORD=keycloak -e POSTGRES_ROOT_PASSWORD=keycloak -d postgres

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:postgresql://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' postgres`:5432/keycloak -Dkeycloak.connectionsJpa.driver=org.postgresql.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop PostgreSQL:

docker rm -f postgres

MariaDB

The simplest way to test with MariaDB is to use the official MariaDB docker image.

Start MariaDB:

docker run --name mariadb -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=keycloak -e MYSQL_USER=keycloak -e MYSQL_PASSWORD=keycloak -d mariadb:10.1

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:mariadb://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' mariadb`/keycloak -Dkeycloak.connectionsJpa.driver=org.mariadb.jdbc.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop MySQl:

docker rm -f mariadb

Using built-in profiles to run database tests using docker containers

The project provides specific profiles to run database tests using containers. Below is a just a sample of implemented profiles. In order to get a full list, please invoke (mvn help:all-profiles -pl testsuite/integration-arquillian | grep -- db- | grep -v allocator):

• db-mysql
• db-postgres

As an example, to run tests using a MySQL docker container on Undertow auth-server:

mvn -f testsuite/integration-arquillian clean verify -Pdb-mysql

If you want to run tests using a pre-configured Keycloak distribution (instead of Undertow):

mvn -f testsuite/integration-arquillian clean verify -Pdb-mysql,jpa,auth-server-quarkus

Note that you must always activate the jpa profile when using auth-server-quarkus.

If the mvn command fails for any reason, it may also fail to remove the container which must be then removed manually.

For Oracle databases, the images are not publicly available due to licensing restrictions.

Build the Docker image per instructions at https://github.com/oracle/docker-images/tree/main/OracleDatabase. Update the property docker.database.image if you used a different name or tag for the image.

Note that Docker containers may occupy some space even after termination, and especially with databases that might be easily a gigabyte. It is thus advisable to run docker system prune occasionally to reclaim that space.

Using DB Allocator Service

The testsuite can use the DB Allocator Service to allocate and release desired database automatically. Since some of the database properties (such as JDBC URL, Username or Password) need to be used when building the Auth Server, the allocation and deallocation need to happen when building the integration-arquillian project (instead of tests/base as it happens in other cases).

In order to use the DB Allocator Service, you must use the jpa profile with one of the db-allocator-*. Here's a full example to run JPA with Auth Server Quarkus and MSSQL 2016:

mvn -f testsuite/integration-arquillian/pom.xml clean verify \
    -Pjpa,auth-server-quarkus,db-allocator-db-mssql2016 \
    -Ddballocator.uri=<<db-allocator-servlet-url>> \
    -Ddballocator.user=<<db-allocator-user>> \
    -Dmaven.test.failure.ignore=true

Using -Dmaven.test.failure.ignore=true is not strictly required but highly recommended. After running the tests, the DB Allocator Plugin should release the allocated database.

NOTE: If you killed the maven surefire test preliminary (for example with CTRL-C or kill -9 command), it will be good to manually release the allocated database. Please check dballocator.uri and add ?operation=report to the end of the URL. Find your DB in the GUI and release it manually.

Below is a just a sample of implemented profiles. In order to get a full list, please invoke (mvn help:all-profiles -pl testsuite/integration-arquillian | grep -- db-allocator-db-):

• db-allocator-db-postgres - for testing with Postgres 9.6.x
• db-allocator-db-mysql - for testing with MySQL 5.7
