testing - Regular expression in While Controller Jmeter

Question

I am using While Controller with Condition:

${_javaScript("${DONE}" ! = "Resolved and Downloaded";)}

where initially DONE="Not Assigned yet".

After few iterations DONE changes and has value Resolved and Downloaded (which I check in Debug Sampler) but loop continues and doesn't quit.

What did I do wrong,What should I do to make it work?

Answer 1

Check syntax of your condition expression first: should be double __ before function name and , instead of ; after condition in function's params list:

${__javaScript("${DONE}"!="Resolved and Downloaded",)}

This can break your test case.
As well you can look into jmeter.log for possible issue details.
