Worked on stabilizing the IOU-ZCRX self-test within the geerlingguy/linux repository, focusing on improving test reliability and consistency across environments. Addressed a missing import exception related to network interface channel configurations, ensuring smoother execution of the self-test flow. Standardized the testing procedure by flipping local and remote endpoints to match other self-tests, which helped reduce CI flakiness and enabled earlier detection of regressions. Utilized Python for scripting and testing, applying network configuration expertise to refine the test setup. The work emphasized robust automation and contributed to more predictable continuous integration outcomes, though it involved bug fixes rather than new feature development.
