title: Jmeter random number generation
body: <p>I have a requirement to generate a random number and use it in subsequent requests. So, before using this newly generated random number in first subsequent request, i need to check if this random number generated is already exists in the application or not by comparing with newly generated response number. So for this validation i am thinking to use an extractor to get the count and eventually verify this is &gt;1 and make it run until this condition is invalid. So in case of random number already exists, i need to generate a new random value since the previous one is already exist in the application. Any snippet i can use here?</p>
