Worked on enhancing the continuous integration and testing infrastructure for the IsaacLab repository within the Isaac Sim pipeline. Focused on improving reliability and feedback speed by introducing a dedicated pytest marker to clearly tag tests intended for CI integration. Refactored the AppLauncher component to remove pytest-related arguments from sys.argv, resulting in cleaner CI test execution and earlier detection of issues. Updated test flags to better support integration scenarios, and reorganized test suites to isolate CI-specific cases. Utilized Python, Pytest, and CI/CD practices throughout, delivering a more maintainable and robust testing workflow for Isaac Sim development and integration.
