Start from auto-wire folder

Starts the server from the given autowire config. An example can be found in the examples folder.

grpc-server-mock start:autowire

Options:

--host     Server host.                                                       [default: "127.0.0.1"]
--port     Server port.                                                           [default: "50051"]
--folder   Path to folder with files for autowireing.                                 [default: "."]
--silent   If set, noop logger will be used                               [boolean] [default: false]
--delay    Delay in milliseconds before returning response.                           [default: "0"]
--ordered  If set, responses will be ordered instead of random.           [boolean] [default: false]
--matched  If set, received inputs will be matched to provided outputs.     [boolean][default:false]

Expected format:

|-- <autowire root folder>
|   |-- <arbitrary folder name that contains proto file and responses>
|   |   |-- <service_from_your_proto>
|   |   |   |-- <your_service_method_name1.json>
|   |   |   |-- <your_service_method_name2.json>
|   |   |-- <_otherservice_from_your_proto>
|   |   |   |-- <your_other_service_method_name1.json>
|   |   |   |-- <your_other_service_method_name2.json>
|   |   |   |-- <your_other_service_method_name3.json>
|   |   `-- <your.proto>
|   |-- <another arbitrary folder name that contains proto file and responses>
|   |   |-- <service_from_your_other_proto>
|   |   |   |-- <your_service_method_name1.json>
|   |   |   |-- <your_service_method_name2.json>
|   |   |-- <_otherservice_from_your_other_proto>
|   |   |   |-- <your_other_service_method_name1.json>
|   |   |   |-- <your_other_service_method_name2.json>
|   |   |   |-- <your_other_service_method_name3.json>
|   |   `-- <your_other.proto>
`

If your service is defined via multiple proto files, please provide the root.json file with the following format:

{
  "root":"<root_proto_name(proto where the service is defined)>.proto"
}

Service method json format for default mode:

[
  {
    "your_message_field_1": "<value>",
    "your_message_field_2": "<value>",
  },
  {
    "your_message_field_1": "<value>",
    "your_message_field_2": "<value>",
  }
]

Service method json format for --matched mode:

[
  {
    "input": {
      "your_message_field_1": "<value>"
    },
    "output": {
      "your_message_response_field_1": "<value>",
      "your_message_response_field_2": "<value>"
    }
  },
  {
    "input": {
      "your_message_field_2": "<value>",
      "your_message_field_3": "<value>"
    },
    "output": {
      "your_message_response_field_2": "<value>"
    }
  }
]

If you wish to ignore certain folders that dont contain method response files, you can do so by adding the ignoreServiceFolders array field in the aforementioned root.json.

The following example will not take the folder common into consideration, when crafting responses, but it will still load .proto files from it.

{
  "ignoreServiceFolders": ["common"]
}
