7.5🔒Q&ACover letter framinggRPC testing requires a protocol-aware approach that differs fundamentally from REST. I work with .proto files as the source of truth…
7.6🔒Q&AInterview framing"I approach gRPC testing contract-first. I start by reading the .proto file -- it tells me every method, every field, and every type before…
7.7🔒Q&AWhat not to say- "gRPC is just like REST but with different serialization." -- This misses fundamental differences: status code systems, streaming…
7.8🔒Q&AQuestion 1Prompt: Your team has a gRPC microservice that returns INTERNAL (the gRPC equivalent of 500) for every error condition -- missing…

7.11🔒URL Path Versioning (Most Common)
7.12🔒Header-Based VersioningThe most important aspect of API versioning testing: old clients must not break when new versions launch.
7.13🔒Sunset Header TestingCOMMON MISTAKE: Assuming that once v2 is released, v1 can be ignored. In practice, v1 may have hundreds of active clients. Always run…
