        When    I want to print the configuration config param "param1" from config.xml

// step_definitions/demo.js ---------------------------------------------------------

var xml2js = require('xml2js')

    xml2js.parseString(`<?xml version="1.0" encoding="UTF-8"?>

        });
    this.When('I want to print the configuration config param "$configParamName"', function(configParamName) {

        console.log(`param ${configParamName} = ${value}`)
    })
