Can i generate a random number without using a data source and have it passed in the rest request?

I need to generate random numbers which needs to be sent for a field call "ID" and there can be multiple occurrences of this field and thus i want to generate a random number for these tags where ever ID is present of a specified length .

 

Some thing like below is what i want to put where ever field ID is present.

 

"id": %STR(6,6,True,false,false,false),
"brand": "e-commerce",
"channel": "online", 

 

I see that it does not work when i tried and i do not want to use Data Source . Any alternate options?

random number
regular expression

    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.

    For example, to use a number between 1, and 1000 thousand, use the following as value for rest request itself. See if the below helps.
    "${= new Random.nextInt(1, 1000)}"

        Sorry, there was typo.
        Change from:
        ${= new Random.nextInt(1, 1000)}

        to

        ${= new Random().nextInt(1, 1000)}

    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)}
