While controller is running infinite loop

On a http response for a http request I am checking a particular field from one status to another status using a while controller. But the while controller is not breaking the loop even after the condition is satisfied.

{
    "data": {
        "uri": null,
        "taskId": "f5b6aaf3-8b14-49ba-a495-788eef5c523b",
        "taskStatus": "Ongoing"
    },
    "apiUrl": "http:\/\/.int:8081\/release01-nightly-api\/\/2192_IND_1_40",
    "statusCode": "102"
}

So the above response "taskStatus": "Ongoing" which will be "Successfull" after some time may be 20-30 seconds so I have used a while controller, which is not breaking even after the condition is satisfied.

Here below the details of while controller, enter image description here I am fetching the status using a JSON extractor enter image description here Execution snapshot, enter image description here What I am doing wrong here

Your expression is wrong, change it to:

${__groovy((!vars.get('task_status').equals('Success') && (vars.get('__jm__While Controller__idx') as int ) < 30),)}

no other changes are required.

Going forward use Debug Sampler to evaluate your expressions

Few things configured wrongly, encountered with similar situation this is the solution we implement,

  1. First http request with json extractor seems fine. [No changes needed]

  2. Now in the while controller please do the changes ${__javaScript("${task_status}"!="Success" && parseInt(vars.get("statusCounter"))<=30)}

  3. Under the while controller start a counter with the following values

    starting value: 0

    increment: 1

    exported variable name : statusCounter [give this name according to your choice]

  4. Under the while controller put the same http request and add a json extractor similar to step 1.

  5. Under this request add a beanshell assertion and following code,

Code Block for the assertion:

try {
    if (vars.get("task_status").equals("Success")) {
        Failure = true;
        FailureMessage = "Workflow Status is not changed : " + vars.get("task_status_Upd");
        SampleResult.setStartNextThreadLoop(true);
    }

    if (vars.get("statusCounter") == 30) {
        Failure = true;
        FailureMessage = "RequestTimeOut";
        SampleResult.setStartNextThreadLoop(true);
    }
} catch (Exception ex) {
    log.info("Error in beanshell", ex);
    throw ex;
}
