Have a requirement to have think time on virtual service on every 10th request.
All supported DevTest releases.
To find out every 10th transaction, add a counter variable and increase that value for each request by adding a custom logic in scriptable data protocol.
Add a "Javascript" step between "VS Image Response Selection" and "HTTP/S Respond" step and add the logic to verify whether counter is multiple of 10. If yes, then use Thread.sleep(10*1000); (Which will keep the thread in wait state for 10 seconds).
