Streaming responses are not streamed

[mseremin]

I try to mock unary-stream response, but I get answer like unary. I mean that in BloomPRC my mock answered to me one time, it is not streaming. Can someone help me to know what I'm doing wrong and explain how I must configure my imposter to get stream response?

Hey @mseremin, sorry for the late response.

I'm not sure if you figured it out yet... to mock a streaming response, you can use a list in the 'value' with multiple responses. When the imposter is setup this way, it'll send back all of values.

Here's an example imposter using the protos from the src/protos directory:

{
    "protocol": "grpc",
    "port": 4545,
    "loglevel": "debug",
    "recordRequests": true,
    "services": {
        "example.ExampleService": {
            "file": "example.proto"
        }
    },
    "options": {
        "protobufjs": {
            "includeDirs": ["/home/cbrz/dev/mbtest/mountebank-grpc/src/protos"]
        }
    },
    "stubs": [{
        "predicates": [
            {
                "matches": { "path": "UnaryStream" },
                "caseSensitive": false
            }
        ],
        "responses": [
            {
                "is": {
                    "value": [
                        {
                            "id": 100,
                            "data": "mock stream response"
                        },
                        {
                            "id": 101,
                            "data": "mock stream response"
                        }
                    ]
                }
            }
        ]
    }]
}

Send a unary request calling the UnaryStream endpoint and you should see two responses.

Let me know if you have any questions/comments. Thanks!
