Re: How to generate random dates
Andrey,
Thank you very much. *reference bookmarked*
I didn't know about the zero-bounded month method. That explains it.
Thanks again.

Re: How to generate random dates
Hi,
please read the reference for javascript Date object - for example here:
https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/Date
As written there, for the Date object "Months: 0 (January) to 11
(December)" - so getMonths() returns the number between 0 and 11 - and
9 corresponds to October and not September.
Javascript should not have a problem with long numbers if the date is
between 1900 and 2100. So the following script
var startMillis = new Date(1900,0,1).getTime(); //Get millis for
January 1st 1900
var endMillis = new Date(2100,0,1).getTime(); //Get millis for January 1st 2100
var randomDate = new Date(startMillis +
Math.random()*(endMillis-startMillis)); //new Date() with millis set
to random value between startMillis and endMillis
randomDate.toUTCString(); //Output UTC string for randomDate
should work fine.
Regards,
Andrey

Re: How to generate random dates
Laurent,
I think Javascript has a problem with the long numbers...
I tried your suggestion but the problem is that javascript cant handle
the longs.
My other attempt:
${__javaScript(var mydate=new Date();
mydate.setDate(mydate.getDate()-${__Random(1,14)});
mydate.getDate()+"/"+mydate.getMonth()+"/"+mydate.getFullYear();)}
also failed, since it always shows me the month of September (9) even
though we are obviously in October and the number of days subtracted
from today should be between 1 and 14
Any ideas where I'm going wrong ?
Thanks !

Re: How to generate random dates
Andrey, All,
I can't seem to get it to generate random dates that have to lie between
two date boundaries. I've tried sth like this (hack !!):
${__javaScript(
var today_date=new Date();
var old_date=new Date();
old_date.setDate(today_date.getDate()-5);
var old_date_int = old_date.getTime();
var today_date_int = today_date.getTime();
var random_date_int=old_date_int
+(Math.random()*(today_date_int-old_date_int));
random_date_int.toUTCString();)}
but when I use this it doesn't evaulate. Does anyone have anything
'out-of-the-box' that works ?
TIA

Re: How to generate random dates
Hi, the best way would be probably randomizing the Time part (the number of milliseconds since 1970/01/01) of the Date(). For example in javascript var mydate=new Date(); mydate.setTime(mydate.getTime()*Math.random()); mydate.toUTCString(); will output a date string in UTC format (like "Sat, 19 Jan 1985 06:22:28 GMT") for a date between now and 1970/01/01.

How to generate random dates
Hi team, I need to generate random dates in JMeter. I know that by merely using the random function and then 'building' the date string I can get 90% of the way there - however, in order no to risk faulty dates, I always lose out on dates after the 28th. The obvious problem here is the interdependency between the months and their respective number of days. Does anyone know of a quick and easy solution ?
