November 2025 – Focused on stabilizing the testing pipeline for RedHatQE/openshift-virtualization-tests by cleaning up Pytest configuration, improving test reporting, and tightening marker organization. Delivered a config cleanup that resolves a Pytest warning and enhances maintainability across CI environments. The commit a4875081f5513d08ac310ad9820041ac66dd4f50 documents the change, moving self_contained_html from pytest.ini to addopts and reorganizing configuration for clarity. In addition, HTML test reports were enabled with self-contained output and collapsible sections to facilitate review and sharing across teams. These changes reduce CI noise, improve reproducibility of test runs, and provide clearer test insights across clusters, hardware, and install/upgrade flows.
