Multi Request

This code example is for standalone script

Create a multiple request script

Create a file at root multi-request.js:

multi-request.js

/**
 * Scenario:
 * Generate requests towards specific domain
 **/
var trafficSimulator = require('flexbench');


function runTest() {
    trafficSimulator.debugMode(true);
    trafficSimulator.testDuration(5);//-1 for infinite run
    trafficSimulator.workers(1);
    trafficSimulator.clients(2)
    trafficSimulator.throttleRequests_bps(50000);//-1 for no throttling
    trafficSimulator.randomDelayBetweenRequests('0.5-1.1');
    trafficSimulator.setFunc('request', requestFunc);

    trafficSimulator.start();

    trafficSimulator.events.on('end', function (msg) {
        //This function will run on exit/stop, when worker has received a message to offload his stats to his master
        //Get from msg object all exposed metrics
        console.log('\nTraffic Simulator Results');
        console.log('-------------------------');

        var cArr = Object.keys(msg.counters);
        for (var i = 0; i < cArr.length; i++) {

        process.exit();
    });

    //stop test after specific period or condition\
    setTimeout(function () {
        trafficSimulator.stop();
    }, 20 * 1000);
