Developed and integrated conditional release-checking system tests for the containers/skopeo and containers/buildah repositories, focusing on enforcing a policy that prohibits release versions with a '-dev' suffix. Leveraged bash and yaml to implement tests that are gated by environment variables, ensuring they only run during targeted release checks and do not disrupt routine CI workflows. Enhanced the TMT test configurations to support upcoming Fedora release cycles and future release validation scenarios. This work emphasized release engineering, system testing, and test automation, providing detailed failure output when policy violations occur and improving the reliability of release processes for both projects.
