Roger Yao engineered robust test automation and infrastructure enhancements for the longhorn/longhorn-tests repository, focusing on disaster recovery, encrypted volume workflows, and end-to-end data integrity validation. He modernized test environments by upgrading Kubernetes, OS images, and Talos Linux, and streamlined CI/CD pipelines using Python, Terraform, and Robot Framework. Roger consolidated manual and automated tests, expanded coverage for node reboot and volume expansion scenarios, and improved test reliability through code refactoring and targeted bug fixes. His work enabled reproducible, maintainable test suites that accelerated feedback cycles, reduced flakiness, and strengthened validation for distributed storage systems across diverse cloud-native environments.
October 2025 monthly summary focusing on key accomplishments in longhorn-tests: automated volume testing enhancements and node-down resilience coverage. Consolidated manual tests into automated suites, tightened prerequisites, and added randomized suffixes to orphaned replica volume names to stabilize automated runs. Added resilience test for multi-node failure scenarios to validate backing images and volumes, and refactored test keywords for accurate state verification and data integrity under failure conditions. These improvements reduced test flakiness, shortened feedback loops, and increased confidence in release quality for storage features.

September 2025 monthly summary focusing on key accomplishments in DR testing and infrastructure automation for the longhorn-tests repository.
This month focused on expanding encrypted volume test coverage and improving test documentation to reduce encryption-related risk and accelerate validation in production. In the longhorn-tests repository, we delivered enhanced test coverage for encrypted volumes, including online expansion of encrypted RWO volumes, stability during node reboots for encrypted RWO/RWX, and negative testing for instance-manager crashes with encrypted volumes. We also updated test documentation and tagging for DR volume negative tests to clarify procedures and link related issues. These efforts increase reliability, enable faster regression detection, and provide clearer guidance for future work across encryption scenarios.
