Go toolchain
Git

Then:

Install xk6:

$ go install go.k6.io/xk6/cmd/xk6@latest

Build the binary:

$ xk6 build --with github.com/dgzlopes/xk6-redis@latest

Example

import redis from 'k6/x/redis';

const client = redis.newClient();

export function setup() {
  redis.set(client,"snake","camel",0)
  redis.set(client,"foo",100,10)
}

export default function () {
  console.log(redis.get(client,"snake"))
  console.log(redis.get(client,"foo"))
  if (redis.do(client,"PING","bzzz") == "bzzz"){
    console.log("PONG!")
  }
}

export function teardown () {
  redis.del(client,"foo")
}

Result output:

$ ./k6 run script.js
