Contributed to the GreenCityMVP21 repository by enhancing backend test coverage and improving code quality for shopping list and habit management features. Focused on developing comprehensive unit tests for the CustomShoppingListItemController and habit mappers, using Java, JUnit, and Mockito to ensure robust validation of retrieval, saving, updating, and bulk operations. Applied the builder pattern and refactored test suites to standardize test data, extract shared constants, and reduce duplication, resulting in more maintainable and reliable tests. These efforts led to faster defect detection, reduced regression risk, and improved CI stability, demonstrating a methodical approach to backend development and test automation.
