I am adding days to the current date but I am getting an invalid date in the result.

I am using BeanShellPreprocessor in Jmeter and using following code to get the current date.

import java.text.SimpleDateFormat; 
import java.util.Date; 
Date date = new Date(); 
date.setDate(date.getDate()+15); 
SimpleDateFormat df = new SimpleDateFormat("MM/DD/YYYY HH:mm a"); 
String formattedDate = df.format(date); 
vars.put("slotFirstCall",formattedDate); 

This code is adding 15 days to the current date but the value I am getting in the variable is 02/33/2018. And it is showing a different date on the calendar. Date on the calendar, where I am using it is 03/05/2018.

If I use this code in Java I get the correct result, but in Jmeter I get the invalid date.

    D (capitalised) means day-in-year. Today is 18th day of the year, so 18+15=33. You probably need "d" which means day of the month.

The code you have provided unlikely implements what you expect. If you refer to SimpleDateFormat specification you will realise that D capitalised represents day of the year but not the day of the month.

Today is 18th day of the year, so 18 + 15 = 33 which does not look surprisingly.

However putting the year day "index" along with the month does not make a lot of sense and does not correspond to any known date-representation format. This makes me think you have a bug in your code.

Change your code to

import java.text.SimpleDateFormat; 
import java.util.Date; 
Date date = new Date(); 
date.setDate(date.getDate()+15); 
SimpleDateFormat df = new SimpleDateFormat("MM/dd/YYYY HH:mm a"); 
String formattedDate = df.format(date); 
vars.put("slotFirstCall",formattedDate);  

this could help.

UPD:

P.S. - It is also worth checking other specificators in your format. Revise if you really need a at the end of your date pattern since a means AM/PM, however you are using HH which represents the time in 24H format. So AM/PM does not introduce any additional value to your timestampt.

This is really a Java-related question as opposed to a JMEter question.

That said, this link shows you how to use the Java Date classes you're using and how to manipulate the date.

The Mykong site is a great source on Java.

  • Adams, The code is working fine in case of java but when I am using the same in Jmeter, showing a different result.

Since JMeter 3.3 you have __timeShift() function which can make your life easier. The relevant function call would be something like:

${__timeShift(MM/dd/YYYY HH:mm a,,P15D,,slotFirstCall)}

Demo:

JMeter Time Shift Example


Also be aware that starting from JMeter 3.1 it is recommended Groovy for all forms of scripting (general recommendation of avoiding scripting where possible still applies)
