Introduction to Testing Unary gRPC Services in Go Testing unary gRPC services in Go is deceptively complex. At first glance, it mirrors HTTP testing—requests, responses, and assertions. But dig deeper, and gRPC’s unique mechanics emerge: its error model, interceptors, metadata, and the need for specialized testing tools. These elements aren’t just features; they’re system mechanisms that demand tailored testing strategies. Ignore them, and you risk inconsistent error handling, metad
