During November 2024, ubuntu@ip-172-31-94-199.ec2.internal developed comprehensive unit tests for the TodoList.list_tasks method in the COSC381-2024Fall/Todo-List-CLI repository. Focusing on test-driven development and unit testing best practices, they designed tests to validate behavior across empty lists, typical task lists, and large lists containing up to 1000 items. This approach ensured correctness and performance under various conditions, reducing the risk of regressions and enabling faster continuous integration feedback. Working primarily in Python, they emphasized edge-case coverage and regression testing, contributing depth and reliability to the project’s core functionality while laying groundwork for future feature stability.
