I am often unit-testing from IDEA with MySQL or PostgreSQL. This might help with table locks. You need to set system properties like (see keycloak-server.json): -Dkeycloak.connectionsJpa.url=jdbc:mysql://localhost/keycloak -Dkeycloak.connectionsJpa.driver=com.mysql.jdbc.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak Also you need to put MySQL dependency to testsuite/integration/pom.xml : <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> or: <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>${postgresql.version}</version> </dependency> This is not needed if you start test from command line with maven, as maven will use the "mysql" or "postgresql" profile and will use dependency by default.
