Filippo Mutta enhanced the testing infrastructure for the luxonis/depthai-core repository by implementing configuration improvements targeting the RVC4 platform and USB environment. He introduced a new environment variable to enable TCP/IP protocol testing on RVC4, which expanded test coverage and improved reliability. By aligning the USB environment with the correct protocol setting, Filippo streamlined end-to-end test runs and reduced configuration drift. His work focused on Python-based test automation, updating scripts such as tests/run_tests.py to support the new configuration. Over the course of the month, Filippo concentrated on feature delivery and test reliability, demonstrating depth in Python and testing practices.
