Worked on the COSC381-2024Fall/Todo-List-CLI repository, focusing on enhancing the reliability of the TodoList.get_total_tasks method through comprehensive unit testing. Applied test-driven development practices in Python to deliver targeted test coverage, ensuring accurate task counting across various list states from zero to four tasks. Anchored tests to a specific commit for traceability, supporting maintainable and reviewable code changes. No major bugs were identified or fixed during this period, reflecting a focus on proactive quality assurance. The work established a robust foundation for future feature expansion and contributed to the overall maintainability and confidence in the codebase.
