Vive la Différence: Practical Diff Testing of Stateful Applications
Summary: A practical diff-testing framework for stateful application rollouts, comparing old/new versions under replayed client workloads. It combines PostgreSQL database branching with efficient branch diffing to expose version-interaction bugs while limiting performance overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
