Liubov Ulitina developed a new 5-link DUT-ATE test topology for the openconfig/featureprofiles repository, enabling more realistic and standardized network testing scenarios. She updated topology configurations, protocol buffer definitions, and testbed files to support complex multi-link validations, reducing manual setup and encouraging higher fidelity in automated test cycles. Her work involved scripting in Shell and editing protobuf files to standardize topology representation for future test automation. Over the course of the month, Liubov focused on network configuration and test automation, delivering a well-integrated feature that enhances the repository’s ability to support advanced, multi-link device validation without introducing new bugs.
