Use InProcessServerBuilder for testing

[asarkar]

Micronaut gRPC creates a NettyServerBuilder automatically. How do I use an InProcessServerBuilder for testing?

One way is to set grpc.server.enabled=false, and then create the Server myself.

Server server = InProcessServerBuilder.forName(uniqueName)
      .directExecutor()
      .addService(new MyService())
      .build().start();

But then, I've to start and stop it. It'd be nice to have the framework manage it on my behalf instead.

Actually I struggled with that, indeed it'd be nice if the framework manages a proper way to mock Grpc services

grpc-spring-boot-starter does this using a property.

@graemerocher I'm willing to submit PR for this, but there will have to be internal design changes. I looked at the code, and it assumes NettyServerBuilder. I'm thinking something like shown in this ticket, so that the builder can be configured using external properties.

Do you've any thoughts on this?

Seems reasonable
