Worked on expanding automated test coverage for the JCSDA-internal/ufo-data repository, focusing on the msonet geovals and obs rrfs components. Enhanced the ctest validation framework by adding two new NC4-format test input files, which broadened the scope of regression detection and improved the reliability of continuous integration workflows. The approach centered on systematic testing, leveraging skills in test design and CI integration to ensure earlier identification of issues. Although no bugs were fixed during this period, the work contributed to higher quality releases by strengthening the testing infrastructure and aligning validation processes with evolving data requirements in the project.
