March 2025 monthly summary for apache/incubator-seata focused on strengthening test infrastructure for the SQL parser across multiple dialects (DM, Kingbase, Oscar). Key delivery was a reorganization and refactor of SQL parser tests, consolidated under a new sqlparser/seata-sqlparser-druid module to improve maintainability and testability. This work is supported by the commit 886874e26eb5ade85f45c65c147c056b7baeb08a (test: add UT for DM/kingbase/oscar sqlparser (#7203)). There were no major bug fixes this month; the emphasis was on quality gains through better test coverage and maintainability. The overall impact is higher confidence in parser correctness, faster iteration on parser changes, and reduced regression risk for multi-dialect support. Technologies/skills demonstrated include Java/Gradle-based project structure, test-driven development, refactoring for maintainability, cross-dialect test coverage, and CI-readiness of the test suite.
