PROFILE
Chris
Chris Chien developed and maintained automated testing infrastructure for the longhorn/longhorn-tests repository, focusing on backup, upgrade, and disaster recovery validation for Kubernetes storage systems. He expanded end-to-end and integration test coverage for V2 volumes, backup stores, and AppCo deployments, using Python, Robot Framework, and Shell scripting to implement robust CI/CD pipelines and cross-environment test automation. His work included automating upgrade and air-gapped deployment tests, enhancing reliability through custom error handling, and improving documentation for onboarding and test setup. By addressing cross-architecture compatibility and test flakiness, Chris delivered deep, maintainable solutions that improved release confidence and operational resilience.

Aug 1, 2025In August 2025, the longhorn-tests team delivered significant CI/CD and test automation enhancements, expanded end-to-end coverage, and improved upgrade reliability, all focused on increasing deployment safety, diagnostics, and disaster readiness. Highlights include: (1) CI/CD pipeline enhancements for Helm integration and air-gap support, enabling Helm login for upgrade tests, air-gap installations, persistent support bundle retrieval, and IPv4-only dependency installation to improve reliability and diagnostics; (2) End-to-end tests for backing image volumes eviction and CSI snapshot handling when an invalid backup target is specified; (3) Disaster Recovery backup system test introducing DR-volume backup validation with assertions on attachment duration and policy compatibility; (4) Upgrade test reliability improvements through test-step refactoring, removal of an unused keyword, and ensuring a consistent backing image manager state post-upgrade. These efforts collectively reduce upgrade risk, improve feedback loops, and strengthen DR readiness while showcasing strong competencies in CI/CD, Helm, E2E testing, and test stabilization.
