Worked on the apache/ignite-3 repository to enhance the reliability of partition recovery validation in distributed systems. Focused on restoring comprehensive test coverage by re-enabling previously disabled JUnit tests, ensuring that partition reset scenarios are now thoroughly validated during continuous integration runs. This approach reduced the risk of undetected regressions and improved the accuracy of partition assignment handling after resets. Leveraged Java and testing frameworks to deliver a targeted bug fix, directly addressing issues outlined in IGNITE-25285. The work contributed to more stable CI pipelines and provided faster feedback on recovery logic, supporting ongoing development and production stability.
