For example, this can be used to assign a distinct user id to be used by each thread. 3. If you want to create a JSON from 3 JMeter Variables you need to do some scripting using any JSR223 Test Element and Groovy language, example code:1 Answer. In this example, these thread groups are named “First Thread Group” and “Second Thread Group. It just needs to be nested under a parent). end indes of loop : $ {folderid_matchNr} output varibale is folderidd. When Constant Throughput Timers are introduced as child to the request JMeter tries to create request to maintain the specified throughput if server can handle them. Start JMeter. But it's not true. Each thread loops through the list of JSON-files for its own. Then use ForEach Controller and feed the variable from JSON Extractor to it. Include Controller. I believe I can use ForEach Controller, and JSON extractor, but I dont know how to build my logic here. How about reading JMeter documentation: JMeter will expose the looping index as a variable named jm __idx. After script finishes you should have 3 more JMeter Variables. 2. If you have more threads than the number of. Throughput Controller will work correct if you have more than single iteration. Here is the regex that works for me : punumber= (d+) If you're parsing html you should consider using something else other than regex to extract info like jsoup. for example the value is 89. - Foreach Controller with input variable prefix "TRANSACTIONIDS", output name "RETURNID" - User Defined Variables config element with the following: XML -> ${XML}<id>${RETURNID}</id>.
