PROFILE
Stefan_bohdan Shcherba
During July 2025, Bohdan Stefan contributed to the GreenCityMVP21 repository by developing comprehensive unit test suites for core data filtering specifications in Java. Focusing on the HabitFactSpecification and ShoppingListItemSpecification components, he applied test-driven development practices using JPA Criteria API and Mockito to validate complex filtering logic, including ID and content-based queries, related entity joins, null handling, and multi-criteria scenarios. His work included detailed test documentation, clarifying implementation details such as Path<Long> usage. These efforts enhanced the reliability and maintainability of backend workflows for habit tracking and shopping lists, reducing regression risk and supporting safer, faster feature development.
