Worked on enhancing the ACL testing framework within the sonic-net/sonic-mgmt repository, focusing on improving the reliability and robustness of network policy validation. Developed pre-validation checks to ensure that ACL rules are active and that the ACL table exists before initiating traffic validation, addressing common sources of flaky tests. Introduced new verification utilities to confirm both ACL table presence and rule status, enabling earlier detection of configuration issues. Leveraged Python for implementation, applying networking and testing expertise to streamline the validation process. These updates strengthened the accuracy of ACL-related tests and contributed to more dependable security policy enforcement in automated workflows.
