Building and Testing a gRPC API from Scratch: Unleash the Potential with Postman - W. Ian Douglas
summary
Postman demonstrates that it has supported gRPC since January 2022 and shows building a protobuf 3 definition, splitting messages into separate .proto files, and generating a request collection that ties to an automatic mock server which updates on save. The demo uses Postman’s UI, environment variables, JavaScript test snippets, and mentions CLI options (Newman/Postman CLI). gRPC adoption sits near ~10–11% in surveys, and streaming behavior requires the connection to close before streaming tests run after close.
