Worked on stabilizing the test suite for the NVIDIA/recsys-examples repository, focusing on improving reliability during pull request validation and continuous integration cycles. Addressed a persistent issue by restoring the test_twin_module.sh script to the main test runner, ensuring that critical test hooks were consistently executed. Refined the optimizer test coverage by removing Adam and AdamW cases from test_twin_module.py, which reduced test flakiness and improved overall CI stability. Utilized Python and Shell scripting to implement these changes, with an emphasis on robust testing practices. The work prioritized long-term maintainability and reliability of automated testing workflows within the project.
