PROFILE
Anat Wax
Over six months, contributed to RedHatQE/openshift-virtualization-tests by building and refining virtualization test frameworks and network automation features. Developed enhancements for Windows VM RDP access, enforced explicit client parameters for resource instantiation, and expanded performance testing scenarios for VM migration using PodAffinity and L2 bridge configurations. Applied Python, Kubernetes, and pytest to refactor test suites, improve CI reliability, and streamline test coverage. Addressed test flakiness by introducing dynamic test marking, robust cleanup routines, and modular shared libraries. The work emphasized maintainability, security, and measurement accuracy, supporting faster validation cycles and more predictable performance across complex virtualization and networking environments.

May 1, 2026May 2026 performance-focused monthly summary for RedHatQE/openshift-virtualization-tests. Delivered features to enable VM migration testing with PodAffinity co-location, and refactored the Stuntime framework for modularity and reuse. Introduced an L2 bridge migration scenario to establish a baseline for cross-network performance testing, and simplified the public Stuntime API to improve usability and future extensibility. Overall, these changes enhance test coverage, measurement reliability, and API consistency, supporting faster validation of migration performance and scalability across environments.

Mar 1, 2026March 2026 monthly summary for RedHatQE/openshift-virtualization-tests focusing on OVN Localnet Migration stuntime scenario delivery. Delivered baseline performance testing scaffold including podAffinity-enabled VM co-location and dynamic affinity updates via set_template_affinity, with a 5-second placeholder global stuntime threshold to support initial calibration. This work establishes a repeatable, data-driven foundation for future OVN localnet migration performance improvements and expands test coverage.

Feb 1, 2026February 2026 (RedHatQE/openshift-virtualization-tests): Delivered significant test improvements for NMState integration and robust cleanup for virtctl expose, driving higher CI confidence, faster feedback, and safer cluster state. Implemented dynamic test marking for nmstate-dependent tests, refactored test collection to reduce false dependencies, and expanded coverage. Added unit tests to validate the new marking logic and trimmed test surface area by removing unused fixtures. Implemented teardown cleanup for services created by virtctl expose to prevent dangling resources, addressing upstream cleanup gaps. Technologies demonstrated include Python pytest dynamic markers, fixtures, CI-friendly test infra, and Kubernetes/OpenShift test orchestration; these changes improve reliability, maintainability, and business value through faster, safer test cycles.

Dec 1, 2025December 2025: OpenShift Virtualization tests focused on reliability, security, and test determinism. Implemented explicit client parameter enforcement across resource instantiation to remove implicit defaults, aligning with upcoming openshift-python-wrapper changes. Updated wrappers, utilities, and test fixtures to require explicit admin_client or DynamicClient usage for cluster- vs user-scoped operations. Fixed an outside-mesh traffic blocking scenario by creating the VM without sidecar injection, ensuring accurate mesh behavior. The changes reduce test flakiness, improve security modeling, and set the stage for smoother CI runs and more predictable performance in production scenarios.
