Khine Zar Hein developed end-to-end tests for the overridden grades banner in the Submitty/Submitty repository, focusing on both student and grader views to enhance UI regression safety. Leveraging Cypress and JavaScript, Khine extended the grade_override.spec.js suite and introduced stable selectors in Twig templates to ensure reliable test automation. The tests were designed to run headlessly in continuous integration environments, aligning with the project’s broader testing strategy and accelerating validation for future grading UI changes. This work addressed a specific workflow, providing clear traceability and a faster feedback loop, and demonstrated depth in automated front end testing and collaboration.
