    While i different options , i found a way to do this and is as below.

     

    ${=org.apache.commons.lang.RandomStringUtils.randomNumeric(5)}

     

    Number 5 represents the length for the number.

Hi Sriraj,

 

Thank you for your post. You can use Groovy script to generate a random number or value. https://www.tutorialspoint.com/groovy/groovy_random.htmFor example, you can add the "TestRunListener.beforeStep" event for a project and use the following script to generate a random number and set the "ID" field:

 

 

import java.util.Random
Random random = new Random()
def min = 1
def max = 10
def randomValue = random.nextInt(max + 1 - min) + min;
def props = testRunner.testCase.getTestStepByName("Request 1")
if(props.hasProperty("ID")){
   props.setPropertyValue("ID", String.valueOf(randomValue) )
   log.info "ID was added: " + randomValue
}

 

 

To generate a random value from a list:

 

 

import java.util.Random 
Random random = new Random()
def min = 1
def max = 10
def list = [6,6,true,false,false,false]

def randomValue = random.nextInt(list.size())
def props = testRunner.testCase.getTestStepByName("Request 1")
if(props.hasProperty("ID")){
   props.setPropertyValue("ID", String.valueOf(list[randomValue]) )
   log.info "ID was added = " + list[randomValue]
}

Thanks for the note. I was looking for one liner code which does the job since i was intending to have that directly placed in the rest request.

 

I found the below to do the job 

 

${=org.apache.commons.lang.RandomStringUtils.randomNumeric(5)}
