Developed an Automated Firewall Testing Framework for the au-ts/lionsos repository, enabling scalable and repeatable validation of firewall components within embedded systems. The work focused on creating end-to-end test scripts in C and Shell, integrating session log capture, and improving output handling to support reliable CI/CD pipelines. Refactoring efforts enhanced code clarity and maintainability, while standardized logging and timeout controls reduced test flakiness and improved reproducibility. By introducing structured autotesting and updating data management, the framework established a foundation for automated, traceable testing processes, accelerating feedback loops and supporting faster release readiness for the LionsOS project’s firewall functionality.
