Jan Jedlicka contributed to the quarkus-qe/quarkus-test-framework repository by engineering robust backend and CI/CD solutions that improved test reliability and deployment consistency. He modernized integration with Keycloak and Kafka, migrated cluster configurations to KRaft mode, and enhanced test coverage for Kubernetes and OpenShift environments. Using Java, YAML, and Docker, Jan streamlined environment configuration, automated build processes, and standardized property naming for cross-platform compatibility. His work addressed cross-database schema migrations, stabilized session-based tests, and reduced CI flakiness. Through careful refactoring and targeted bug fixes, Jan delivered maintainable, production-ready infrastructure that supports scalable testing and secure, future-proofed development workflows.

May 2025: Delivered migration of Kafka clusters to KRaft mode in quarkus-qe/quarkus-test-framework, replacing ZooKeeper-based configuration with KRaft-enabled settings and modernizing the cluster setup for better scalability and maintenance. The work removes ZooKeeper-specific configurations, enables KRaft in the Kafka resource, and introduces node pools and KRaft annotations to prepare for future upgrades and operational simplicity. This aligns with long-term Kafka modernization goals and reduces operational complexity while improving reliability.

April 2025: Stabilized and modernized the quarkus-test-framework to ensure reliable cross-version testing of Keycloak with Quarkus. Key deliveries include aligning the test infrastructure to Keycloak 26.1, restoring full TLS CLI integration test coverage by removing outdated version restrictions, and updating the Keycloak image to 26.1 to match Quarkus 26.1.3. These changes reduce flakiness, improve feedback loops, and preserve test coverage across supported versions.

March 2025 — quarkus-test-framework: Reliability fixes and configurability improvements to accelerate testing and reduce flakiness in CI. Key work delivered three targeted changes: (1) resource path correction when copying files to Docker containers to remove a stray '|' and prevent path resolution errors; (2) build-time properties for init-task Flyway container image and pull policy to improve test scaffolding; (3) removal of withKraft() in ExtendedStrimziKafkaContainer to align with Strimzi ZooKeeper deprecation, reducing maintenance burden. Result: more stable test runs, easier test customization, and up-to-date container interop.

January 2025 monthly summary for the quarkus-test-framework: delivered key test-environment enhancements and CI hardening. Upgraded Keycloak to version 26.0 in the test environment and aligned realm import naming with Keycloak conventions, ensuring templates and container services operate with compatible settings. Modernized admin credentials handling by migrating to KC_BOOTSTRAP_ADMIN_USERNAME and KC_BOOTSTRAP_ADMIN_PASSWORD, while maintaining backward compatibility and planning removal of legacy variables. Improved CI workflow by removing an unnecessary Maven setting in Jacoco and expanding release checks to fetch more releases for accurate identification of older stable versions. These changes reduce upgrade friction, improve testing reliability, and strengthen security and governance around credentials.
