Example of using processors in Artillery

my-test.yml

config:
  target: "http://localhost:8080"
  phases:
    - duration: 60
      arrivalRate: 1
  processor: "./processor.js"
scenarios:
  - name: "Load the options page"
    flow:
      - get:
          url: "/some/endpoint"
          afterResponse: "calculateResponseTimeDelta"

processor.js

'use strict';

module.exports = {
  calculateResponseTimeDelta: calculateResponseTimeDelta
};

function calculateResponseTimeDelta(requestSpec, response, context, ee) {
  // requestSpec will be the request spec for this response (currently always null)
  // response is a Request.js response object
  // context is the scenario context containing scenario variables
  // ee is an event emitter for this scenario that we can use to add custom stats to the report
  
  var responseTime = Number(response.headers['x-response-time'].split('ms')[0]);
    
  ee.emit('customStat', { stat: 'response_time', value: responseTime });
}

Is it possible to use breakpoints in the script?
