Worked on the SME-NovoSGP repository to expand and consolidate unit test coverage for scheduling-related scenarios, particularly focusing on Diario de Bordo and knowledge area flows. Emphasized test correctness and code cleanliness by removing unused directives and refining test references, which improved maintainability and test reliability. Utilized C#, MediatR, and Xunit to validate mediator and query handler logic for class scheduling and attendance management, ensuring robust testability and alignment with CI feedback loops. The work enhanced the readability and maintainability of the test suite, supporting faster feedback cycles and contributing to the long-term reliability of core scheduling features.
