During September 2025, Bee Chen focused on enhancing test stability for the mybatis-dynamic-sql repository by addressing flakiness in JoinMapper-related tests. Using Kotlin and leveraging skills in test automation and unit testing, Bee replaced order-dependent assertions with order-insensitive ones, ensuring that test outcomes no longer varied with row ordering. This technical adjustment eliminated intermittent failures in DeprecatedJoinMapperTest and JoinMapperNewSyntaxTest, leading to more deterministic and reliable CI feedback. Although no new features were added, Bee’s targeted bug fix improved the overall robustness of the test suite, streamlining the development workflow and maintaining consistent production behavior without introducing regressions.
