Building micro-services using Go and gRPC brings with it a lot perks, however testing gRPC API is not that trivial. Before calling any gRPC method one need to compile Protobuf messages to your language of choice. Once compiled you are left with Stubs (clients) which you use to test different scenarios. Some of you are probably familiar with Gatling and using it to test your REST APIs. Out of the box, it supports only HTTP/1, but the core engine is actually protocol agnostic. In this session I will show how it's possible to test gRPC using our soon to be open sourced Gatling "plugin".
