Worked on the kubernetes-sigs/headlamp repository to enhance the testability of Kubernetes StatefulSet components in the frontend. Introduced a mock for the labelSelectorToQuery function, which improved the reliability and coverage of tests for features dependent on StatefulSets. This approach reduced the risk of regressions in cluster-management workflows and enabled faster, safer releases. The work was implemented using React and TypeScript, with a focus on front end development and testing best practices. No major bugs were addressed during this period, but the contribution strengthened the overall quality and maintainability of Kubernetes-backed features within the project’s frontend architecture.
