Grpc-java - simulating disconnect from a streaming response api

[aru...@gmail.com]

Hi,

We want to force the grpc client to disconnect from a streaming response API in a test case. I could not figure out how to do that.

Maybe you could do something like this:

CancellableContext context = Context.current().withCancellation();

context.run(() -> stub.doStream(StreamRequest.getDefaultInstance(), new TestStreamObserver()));

...

context.cancel(io.grpc.Status.ABORTED.asException());

Is it client-side application or server-side service implementation you are testing?

Are you trying to simulate stream closure or connection closure?

Are you using the in-process transport?

Hi,

I am testing client side application. I am trying to close the stream and not the whole connection. No, client and server are two different process communicating over network.

You can call onCompleted on the stub to end the stream.    Is there something more you wanted to do?
