Jmeter is one of the most popular open source load testing tool. Jmeter itself has some of the built in functions which we need regularly while creating script like.

  • Base encoding
  • Generating time in different formats
  • Url encode
  • Url decode
  • Random String
  • Random Number
  • UUID
  • Random Date
  • File to string
  • CSV Reader
  • timeshift

In some scenarios we need to use future date to complete the flow like example when user trying to book a flight or placing food order user need to choose future time whether it may be in minutes or hour or even days

In jmeter we have a function name __timeShift  which will allow use to create future date in any format.


Go To Function Helper Dialogue option is changed in latest version of jmeter


Then select __timeShift  function like below

in  First row we need to mention which Format we need like below.

dd-MM-yyyy hh:mm:ss 

For more Patterns info

Letter for Pattern Date or Time component Examples
G Era designator AD
y Year 2019(yyyy),19(yy)
M Month in year July(MMMM), Jul(MMM), 07(MM)
w Results in week in year 30
W Results in week in month 2
D Gives the day count in the year 266
d Day of the month 09(dd), 9(d)
F Day of the week in month 4
E Day name in the week Monday, mon
u Day number of week where 1 represents Monday, 2 represents Tuesday and so on 2
a AM or PM marker AM
H Hour in the day (0-23) 12
k Hour in the day (1-24) 23
K Hour in am/pm for 12 hour format (0-11) 0
h Hour in am/pm for 12 hour format (1-12) 12
m Minute in the hour 16
s Second in the minute 20
S Millisecond in the minute 560
z Timezone Indian Standard Time; IST; GMT-05:30
Z Timezone offset in hours (RFC pattern) -0800
X Timezone offset in ISO format -08; -0800; -08:00

In second row from which date you want to change by default it will be current timestamp if we need we can give another time

In third row need to time shift duration whether it can be in minutes,  seconds, hours ,days,

Examples :

  • PT15M parses as 15 minutes( adds 15 Minutes for given time in second row )
  • PT10H parses as 10 hours(Adds 10  Hours  for given time)
  • P2D parses as 2 days(adds 2 days  for given date in Second row)
  • -P6H3M parses as -6 hours and -3 minutes(subtracts  6 hours 3 minutes from given date in second row )

H  : H stands for hours

M : M Stands for Minutes

S  : S  Stands for Seconds

D  : D Stands for Days

P  : P stands for Adding

-P : Stands for Subtracting

In Fourth row we can save the create Date into variable.

This tutorial will help you in decoding JWT token and sent by server to client.

First how to identify the string is JWT token or some other String generated by Server.

  • If the string is JWT then string should contain 3 dots (header,body,Signature).

Recently most of the applications are using JWT for adding security to their application.

lets assume generated Jwt Token is like below

Create a beanshell sampler with below code

in above bean shell sampler.

  • first getting the jwt token into bean shell sampler.
  • then splitting the string with .(dot). JWT will having 3 sections (header,body,Signature).
  • taking the first index of created array(if you want to decode the header section then change the index from 1 to zero in bean shell sampler ).
  • replacing all _ values with slash(/).
  • doing base 64 decode and adding it to jmeter variables.

executed the bean shell sampler and below is the decoded response is below

if you want to capture values from JWT token the add json path extractor to decoded variable from beanshell sampler.



how to create json web token (jwt) using java

In this tutorial we will see how we gonna create json web token using java

How to Create JWT token in java.


Create a simple maven project. add below dependency

Below is the Code to generate the JWT token

in above code we are creating the JWT token for Map object with subject as json web token. generated jwt token is using SignatureAlgorithm.HS512.  we can use the different algorithms by referring api.

below are all available algorithms

Created token will be looks like below


For Decoding the JWT Token below is the code

Jwstoken  is the token generated and sent to client.

below is the complete class for encoding and decoding of JWT



Note: For decoding JWT Token setSigningKey should be same as the Key used for encoding
