Worked on enhancing test reliability in the snowpark-java-scala repository by addressing flakiness in Self-Join tests within the Java API. Focused on making these tests order-independent, the solution involved updating test assertions to avoid reliance on result-set ordering, thereby reducing false negatives in continuous integration runs. Utilized Java and Scala for both implementation and unit testing, applying API testing best practices to strengthen the overall test suite. This change improved the determinism of CI pipelines and reduced maintenance overhead associated with flaky tests, contributing to more robust cross-language testing and laying a stronger foundation for future development in the repository.
