Constants

Define constants to distinguish between gRPC Response statuses.

Constant	Description
`StatusOK`	OK is returned on success.
`StatusCanceled`	Canceled indicates the operation was canceled (typically by the caller).
`StatusUnknown`	Unknown error.
`StatusInvalidArgument`	InvalidArgument indicates the client specified an invalid argument.
`StatusDeadlineExceeded`	DeadlineExceeded means operation expired before completion.
`StatusNotFound`	NotFound means some requested entity (e.g., file or directory) was not found.
`StatusAlreadyExists`	AlreadyExists means an attempt to create an entity failed because one already exists.
`StatusPermissionDenied`	PermissionDenied indicates the caller does not have permission to execute the specified operation.
`StatusResourceExhausted`	ResourceExhausted indicates some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
`StatusFailedPrecondition`	FailedPrecondition indicates operation was rejected because the system is not in a state required for the operation’s execution.
`StatusAborted`	Aborted indicates the operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc.
`StatusOutOfRange`	OutOfRange means operation was attempted past the valid range. E.g., seeking or reading past end of file.
`StatusUnimplemented`	Unimplemented indicates operation is not implemented or not supported/enabled in this service.
`StatusInternal`	Internal errors. Means some invariants expected by the underlying system have been broken.
`StatusUnavailable`	Unavailable indicates the service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations.
`StatusDataLoss`	DataLoss indicates unrecoverable data loss or corruption.
`StatusUnauthenticated`	Unauthenticated indicates the request does not have valid authentication credentials for the operation.

Example

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,
  });

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