Better default user agent for http requests

[ash211]

Version info:

Artillery: 2.0.21
Node.js:   v22.9.0
OS:        darwin

Running this command with an http request configured:

artillery run artillery-load-test.yml

I expected to see requests in my logs a request with a user agent that says something about artillery, like this: Artillery/2.0.21 Node.js/v22.9.0 darwin

Instead the default user agent is got (https://github.com/sindresorhus/got)

For reference, Apache Bench's user agent is ApacheBench/2.3

An example with an http request is the sample

That's odd. The default user-agent header is set to Artillery (https://artillery.io) here:

https://github.com/artilleryio/artillery/blob/main/packages/core/lib/engine_http.js#L441

Just verified it with:

nc -l 10111
artillery quick http://127.0.0.1:10111/

❯ nc -l 10111
GET / HTTP/1.1
user-agent: Artillery (https://artillery.io)
accept-encoding: gzip, deflate, br
Host: 127.0.0.1:10111
Connection: keep-alive

Hmm, maybe it has something to do with the default headers settings in my artillery-load-test.yml?

  defaults:
    headers:
      accept: 'application/json'
      accept-language: 'en-US,en;q=0.9'
      authorization: 'Bearer {{ $env.TOKEN }}'
      content-type: 'application/json'
      cookie: 'TOKEN={{ $env.TOKEN }}'
      origin: 'https://mydomain.com'
      priority: 'u=1, i'

Hypothesis: when you set default headers, you lose the default artillery user agent.
