Jmeter: While controller

Question

I am load testing a web site. I have request "A" and "B". For request "A", i have a parameter field "Quantity", where i am passing values as 1, 10, 15 and 16 through csv files. And from same request , i am extracting ""Quantity", through regex and passing it to request "B". Request "B" is placed under while controller and i have user function in while controller as ${__javaScript(${QUANTITY}<10),}

Request B is executed for infinite time and each time parameter fetched is "1".

Kindly provide your valuable suggestions for above scenario, since i want the request to fetch value "1", execute it and come out of the while loop.

Answer 1

Your JavaScript expression is incorrect

${__javaScript(${QUANTITY}<10,)}  - correct one
${__javaScript(${QUANTITY}<10),}  - your one

Comma should go after 10, not after the closing bracket. Use The Function Helper Dialog in order to create syntaxically correct JMeter Functions.
