Thanhthuy Dao focused on improving code quality and test coverage for the UQcsse3200/2024-studio-2 repository during August 2025. She addressed two inventory-related bugs by refining Javadoc formatting and aligning documentation with Jacoco code coverage requirements. Working primarily in Java, she emphasized code cleanup and coverage accuracy, ensuring that Jacoco reports now reflect the true extent of tested code. Her approach enhanced maintainability and provided more reliable metrics for future releases. Through clear commit practices and attention to documentation, Thanhthuy contributed to a more robust development workflow, supporting better decision-making and reducing risk in the release process.
