How to use aggregateResult?

[wsierakowski]

I have the following script:

const autocannon = require('autocannon');

const test = async () => {
  const result1 = await autocannon({
    url: 'https://google.com',
    connections: 10, //default
    pipelining: 1, // default
    duration: 10, // default
    skipAggregateResult: true
  });

  const result2 = await autocannon({
    url: 'https://microsoft.com',
    connections: 10, //default
    pipelining: 1, // default
    duration: 10, // default
    skipAggregateResult: true
  });

  autocannon.aggregateResult([result1, result2]);
};

test();

This returns:

node_modules/autocannon/lib/validate.js:88
    return new Error('url or socketPath option required')

Hello @wsierakowski,

This tool is intended for load-testing your own servers. Firing requests over to someone else's server might seem like a DDoS attempt which may result in severe consequences.

That being said, the aggregateResult function gets two parameters: one array with your autocannon instances' results(with skipAggregateResult set to true, as you have done) and an opts object with a required url field. You are missing the second param.

autocannon.aggregateResult([result1, result2], { url: 'http://some-url' });
