We developed a Replay Testing tool to verify that idempotent APIs were migrated correctly from the GraphQL Shim to the Video API service. The Replay Testing framework leverages the @override directive available in GraphQL Federation. The Falcor API had become a logic-heavy monolith with over a decade of tech debt.
