Generating random PESEL

This post will be useful mostly for Polish users. It’s about generating random PESEL number with a single command in Selenium IDE. The goal is to provide you with ready to use code so that you don’t have to invent a wheel again.

I go to sleep. Don’t sit up late.

So don’t sit up late just start using it. Two remarks:

1. Javascript code used to create Selenium command generating random PESEL was found by me on this website: http://itraport.pl/tools/generator-numerow-pesel/. I modified it to run it on Selenium IDE but most credits goes to guy who developed it who is, I believe, Tomasz Wesołowski.
2. To use it:
1. Create (if you don’t have already) new .js file in text editor, name it e.g. “user-extensions.js”
2. Place the code in this file.
3. Add path to the file in Selenium > Options > Options, e.g.

  

 

1. Click “OK” and re-open Selenium
2. New command “TypeRandomPesel” will be available
3. Use it like this:

 

Here’s the code:

Selenium.prototype.doTypeRandomPesel = function(locator){

var initialDate = new Date();
var curr_year = initialDate.getFullYear();
//below string - describes lower boundary of years used to generate PESEL; in this case it's minus 100 years from present year
var curr_yearMinus100 = curr_year - 100;
//below two strings - describes upper boundary of years used to generate PESEL; in this case it's minus 19 years from present year
//in first string it's "curr_year - 18" because string generating random number will add +1 so "curr_year - 18" in fact means "curr_year - 19"
var curr_yearMinus19 = curr_year - 18;
var curr_yearMinus19_2 = curr_yearMinus19 - (curr_year - 100);

var rok = Math.floor(curr_yearMinus19_2*Math.random()+curr_yearMinus100);

var miesiac = Math.floor(12*Math.random()+1);

var dzien = Math.floor(28*Math.random()+1);

/*
var rok = document.getElementById('rok');

var miesiac = document.getElementById('miesiac');

var dzien = document.getElementById('dzien');

var plec_k = document.getElementById('plec_k');
var plec_m = document.getElementById('plec_m');
var plec_l = document.getElementById('plec_l');
var pesel_gen = document.getElementById('pesel_gen');
pesel_gen.innerHTML = "";
var data_urodzenia_gen = document.getElementById('data_urodzenia_gen');
data_urodzenia_gen.innerHTML = "";
var plec_gen = document.getElementById('plec_gen');
plec_gen.innerHTML = "";
