Edi Wibowo enhanced test reliability and deployment confidence in the sonic-net/sonic-mgmt repository by developing a robust PFC watchdog test that introduced dynamic port selection using Python and pytest. By replacing static port assignments with a dynamic fixture, Edi improved test flexibility and adaptability for real-world network configurations. Additionally, Edi addressed topology teardown stability by implementing a fallback default for VM_targets, preventing errors when VMs are not required. This work reduced flaky test runs and improved CI stability, demonstrating depth in test automation, dynamic resource management, and infrastructure as code practices using Ansible and YAML within a DevOps workflow.
