Test gRPC services with gRPCurl
The gRPC functions can only be called by gRPC clients. My team just started migrating to gRPC stack, and I found gRPCCurl is a very helpful CLI tool to test and debug.

Usage
Start your gRPC service and check the service metadata. My service is running on port of 10030.
Use "-plaintext" if your service does not use TLS.
grpcurl -plaintext localhost:10030 describe
grpc.health.v1.Health is a service:
service Health {
rpc Check ( .grpc.health.v1.HealthCheckRequest ) returns ( .grpc.health.v1.HealthCheckResponse );
rpc Watch ( .grpc.health.v1.HealthCheckRequest ) returns ( stream .grpc.health.v1.HealthCheckResponse );
}
grpc.reflection.v1alpha.ServerReflection is a service:
service ServerReflection {
rpc ServerReflectionInfo ( stream .grpc.reflection.v1alpha.ServerReflectionRequest ) returns ( stream .grpc.reflection.v1alpha.ServerReflectionResponse );
