How to mock out grpc status code and headers?

[scvnc]

I want to verify how my app behaves when the grpc status code is 9 and particular metadata headers (X-DETAIL-CODE) are being sent, as this is how I am tranmitting error details to my client.

It seems unclear how to do this with the json stub definition or if it's currently possible.

Thanks :)

I would also be interested in mocking status codes.
There is also this old issue on that: #21.

#144 I'm working on it
