grpc-echo-server

A simple gRPC server that takes a Status Code and returns a response after the configured delay.

If the Status Code is an error (greater than 0), this will be raised as a gRPC error.

Example

OK

grpcurl --emit-defaults -plaintext -d '{"code": 0, "delay": 10}' localhost:4770 io.github.bcarter97.echo.v1.Echo/Echo

{
  "code": 0,
  "delay": "10"
}

Error

grpcurl -plaintext -d '{"code": 14, "delay": 500}' localhost:4770 io.github.bcarter97.echo.v1.Echo/Echo

ERROR:
  Code: Unavailable
  Message: UNAVAILABLE after 500 milliseconds
