Worked on the hpi-schul-cloud/e2e-system-tests repository to enhance end-to-end test reliability for kebab (three-dot) menu interactions. Focused on standardizing interaction patterns by introducing a generic action selector and updating test steps to align with the current UI, which improved both consistency and maintainability across the test suite. Leveraged Cypress and JavaScript to reduce flaky tests and support faster, safer UI changes. Demonstrated attention to version control hygiene and robust test data patterns, ensuring that automated tests accurately reflected room and board management features. The work enabled more efficient QA processes and facilitated ongoing UI development with greater confidence.
