os-testr

os-testr is a Python library that acts as a wrapper for the `testr` (now often `stestr`) test runner, specifically providing additional functionality and integrations tailored for OpenStack projects. It enables features like `subunit-trace` for output filtering, `subunit2html` for HTML test reports, and `generate-subunit` for single test streams. The current version is 3.0.0, and its major release cadence is infrequent, typically aligning with broader OpenStack development cycles.
