Contributed to the GreenCityMVP21 repository by enhancing backend reliability and test coverage for EcoNews features using Java, Mockito, and JUnit. Focused on robust language validation and DTO/VO mapping, migrating tests from PowerMock to Mockito to reduce fragility and streamline maintenance. Expanded unit tests to cover edge cases and improved test feedback loops, supporting safer refactoring. Delivered clear API error handling and response documentation, tightening access control to prevent unauthorized deletions. Refactored test classes to align with Java conventions, improving code maintainability. These efforts strengthened API reliability, security, and code quality, enabling faster iteration and clearer validation across core backend flows.

Jun 1, 2025June 2025 performance summary for GreenCityMVP21: Strengthened test quality and reliability, focusing on language validation and EcoNews DTO/VO mappings. Migrated testing from PowerMock to Mockito to reduce fragility and improve maintenance. Expanded unit tests for LanguageValidator (valid/invalid language codes, null/empty inputs) and added edge-case validations. Implemented comprehensive EcoNews unit tests for DTO/VO mappers (authors, comments) and the main EcoNews entity, plus cleanup to streamline tests. This work reduced defect risk, improved test feedback loops, and laid groundwork for safer refactors in core data validation and mapping logic. Key stakeholders can expect faster feedback during CI, safer refactors, and clearer test coverage signals across validation and data-maçhing flows.
