Jmeter generate random domain name

Question

How can I generate random domain name in using JMeter?

This is what I tried:

Random Variable

VariableName=domainName
OutputFormat=00000.com
MinumumValue=Aa
MaximumValue=Zz
SeedForRandomFunction=__RandomString

Answer 1

Though you have not mentioned which type of random domain names you want, I have considered some examples,

domain_00001.com
domain_03000.com

etc.

This can be created like,

In Beanshell preprocessor this code should yield the desired output, change it accordingly as per need.

import java.util.Random;

public class MyDomainRandomGen {

    private static final String CHAR_LIST ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
    private static final int RANDOM_STRING_LENGTH = 10;

    public String generateRandomDomain(){

        StringBuffer randStr = new StringBuffer();
        for(int i=0; i<RANDOM_STRING_LENGTH; i++){
            int number = getRandomNumber();
            char ch = CHAR_LIST.charAt(number);
            randStr.append(ch);
        }

        String[] domains = {"de","com","in","en","us"};

        int idx = new Random().nextInt(fruits.length);
        String random = (fruits[idx]);

        randStr.append(random)

        return randStr.toString();
    }
}
