Worked on the ansys/pyspeos repository to implement cross-version testing for Speos RPC, focusing on validating compatibility across versions 251, 252, and the development branch. Enhanced the continuous integration pipeline using Docker and Python, enabling parallel test execution against multiple Speos versions to improve coverage and reduce validation time. Updated documentation in Markdown and YAML to clearly describe the new multi-version testing capabilities and marker usage, ensuring maintainability and clarity for future contributors. The work centered on strengthening CI/CD processes and testing infrastructure, delivering a robust foundation for ongoing feature validation without introducing any bug fixes during the period.
