k6/net/grpc

Note

A module with streaming support exists.

The new k6/experimental/grpc module extends k6/net/grpc to support gRPC streaming. We recommend using the new module.

The k6/net/grpc module provides a gRPC client for Remote Procedure Calls (RPC) over HTTP/2.

Class/MethodDescription
ClientgRPC client used for making RPC calls to a gRPC Server.
Client.load(importPaths, …protoFiles)Loads and parses the given protocol buffer definitions to be made available for RPC requests.
Client.connect(address [,params])Connects to a given gRPC service.
Client.invoke(url, request [,params])Makes an unary RPC for the given service/method and returns a Response.
Client.close()Close the connection to the gRPC service.
ParamsRPC Request specific options.
ResponseReturned by RPC requests.
ConstantsDefine constants to distinguish between gRPC Response statuses.

gRPC metrics

k6 takes specific measurements for gRPC requests. For the complete list, refer to the Metrics reference.

Example

JavaScript 
import grpc from 'k6/net/grpc';
import { check, sleep } from 'k6';

const client = new grpc.Client();
client.load(['definitions'], 'hello.proto');

export default () => {
  client.connect('grpcbin.test.k6.io:9001', {
    // plaintext: false
  });

  const data = { greeting: 'Bert' };
  const response = client.invoke('hello.HelloService/SayHello', data);

  check(response, {
    'status is OK': (r) => r && r.status === grpc.StatusOK,
  });

  console.log(JSON.stringify(response.message));

  client.close();
  sleep(1);
};
