Worked on enhancing the testing infrastructure for the apache/nifi repository by upgrading the Testcontainers library from version 1.21.0 to 1.21.1. This update focused on improving test stability and reducing flaky tests, thereby increasing the reliability of continuous integration pipelines and supporting smoother release cycles. The approach centered on dependency management and rigorous testing practices, ensuring that the test environment could better surface issues before deployment. By documenting the changes and integrating them into the existing Java-based codebase, the work contributed to a more robust foundation for future development and release readiness within the Apache NiFi project.
