Tristan Garwood upgraded the continuous integration test environment for the broadinstitute/sam repository by migrating its database from PostgreSQL 9.6 to PostgreSQL 15. This work focused on improving test reliability and compatibility, ensuring that automated tests accurately reflected production capabilities. Tristan used YAML to configure the CI pipeline and applied database management skills to maintain a reproducible environment. The upgrade reduced the risk of flaky tests and unexpected failures, streamlining the release process. By documenting changes and maintaining clear traceability through commit history and pull requests, Tristan demonstrated a methodical approach to CI/CD practices within a modern development workflow.
