Phase 8: Add comprehensive integration tests with real Schema Registry
Phase 8: Add comprehensive integration tests with real Schema Registry
- Add full end-to-end integration tests for Avro workflow - Test producer workflow: schematized message encoding and decoding - Test consumer workflow: RecordValue reconstruction to original format - Add multi-format support testing for Avro, JSON Schema, and Protobuf - Include cache performance testing and error handling scenarios - Add schema evolution testing with multiple schema versions - Create comprehensive mock schema registry for testing - Add performance benchmarks for schema operations - Include Kafka Gateway integration tests with schema support Note: Round-trip integrity test has known issue with envelope reconstruction.pull/7231/head
