k6 v0.24.0 released

The latest release of k6 is...not v1.0, but an intermediate release preparing for some upcoming bigger changes that we want to get into k6 before we cut a v1.0 release. There are however some interesting additions, and bug fixes, in this release:

• CLI: You can now specify a CLI flag --console-output (or K6_CONSOLE_OUTPUT environment variable) to redirect output from the console.log() family of APIs to a file. Thanks to @cheesedosa for this feature!

• New results output: StatsD and Datadog. You can now output any metrics k6 collects to StatsD or Datadog by running k6 run --out statsd script.js or k6 run --out datadog script.js respectively. Thanks to @ivoreis for their work on this!

• k6/crypto: random bytes method. This feature adds a method to return an array with a number of cryptographically random bytes.

  import crypto from 'k6/crypto';
  
  export default function () {
    const bytes = crypto.randomBytes(42);
  }

  Copy

  Thanks to @bookmoons for their work on this!

• k6/crypto: add a binary output encoding to the crypto functions. Besides hex and base64, you can now also use binary as the encoding parameter for the k6 crypto hashing and HMAC functions.

• Error codes: we’ve unified the handling of error codes. k6 will now emit an error_code tag in the metrics output (and expose a property with the same name on http.Response) when there’s an error in making a request.
