Build

To build a k6 binary with this plugin, first ensure you have the prerequisites:

• Go toolchain
• Git

Then:

1. Install xk6:

go install github.com/k6io/xk6/cmd/xk6@latest

1. Build the binary:

xk6 build master \
  --with github.com/NAlexandrov/xk6-tcp

Example

import tcp from 'k6/x/tcp';
import { check } from 'k6';

const conn = tcp.connect('host:port');

export default function () {
  tcp.writeLn(conn, 'Say Hello');
  let res = String.fromCharCode(...tcp.read(conn, 1024))
  check (res, {
    'verify ag tag': (res) => res.includes('Hello')
  });
  tcp.close(conn);
}
