Worked on enhancing gRPC streaming reliability in the keploy/keploy repository, focusing on improving test capture fidelity and stabilizing mock management for concurrent streams. Developed a feature in Go that introduced static deduplication to ensure unique mock-window naming, preventing collisions and redundant test case capture. Improved error handling by promoting initial headers to trailers and implementing deep-copy of header maps to avoid unintended mutations. Enhanced status code validation for gRPC by ensuring deterministic mismatches on non-numeric trailer values. These backend development efforts aligned with production-grade reliability goals, reducing false positives and accelerating feedback for gRPC workloads using HTTP/2 protocols.
