'Sample result's label is not changed through BeanShell post processor for some conditions

I made this code so that if status == 500 the name of the api would be equal to "FAKE_CLIENT_RETRY", if the status of the api == "ERROR", the name would be equal to "FAKE_CLIENT_CALLBACK_ERROR"

import org.apache.jmeter.samplers.SampleResult;

//process main sample
if(("${status}").equals("500")) {

    SampleResult.setResponseCodeOK();
    SampleResult.setSuccessful(true);
    
vars.put("Api_Fake_Client_Name","FAKE_CLIENT_RETRY");
     
}else if(("${status}").equals("ERROR")){
    
        SampleResult.setSuccessful(false);
vars.put("Api_Fake_Client_Name","FAKE_CLIENT_CALLBACK_ERROR");

}else{
vars.put("Api_Fake_Client_Name","FAKE_CLIENT_CALLBACK_SUCESS");
    
}

But even when status == "ERROR" the name it returns is "FAKE_CLIENT_RETRY"

The strangest thing is that I know that the execution entered the "if" of the condition == "ERROR", because the return that comes with status == "ERROR" appears with execution failure in Jmeter and I forced the return in this case to return with fails via code snippet:

SampleResult.setSuccessful (false);

But despite having entered, it ignores the snippet that asks to rename the api.

Following script worked without any issue within BeanShell Post Processor



if(("${status}").equals("500")) {
        prev.setResponseCodeOK();
        prev.setSuccessful(true);
        prev.setSampleLabel("FAKE_CLIENT_RETRY");
        vars.put("Api_Fake_Client_Name","FAKE_CLIENT_RETRY");
        
     
}else if(("${status}").equals("ERROR")){
        prev.setSuccessful(false);
        prev.setSampleLabel("FAKE_CLIENT_CALLBACK_ERROR");
        vars.put("Api_Fake_Client_Name","FAKE_CLIENT_CALLBACK_ERROR");

}else{
        prev.setSampleLabel("FAKE_CLIENT_CALLBACK_SUCESS");
        vars.put("Api_Fake_Client_Name","FAKE_CLIENT_CALLBACK_SUCESS");
    
}

Please note that you have access to the SampleResult through the variable previous. Lets use prev.setSampleLabel("Label"); to set the label of the sample result.

prev - (SampleResult) - gives access to the previous SampleResult

Migration to JSR223 PostProcessor+Groovy is highly recommended for performance, support of new Java features and limited maintenance of the BeanShell library

Add a Debug Post Processor to view the JMeter variables through view result tree.

Sample test plan (JMX) is available in GitHub.

You're setting an Api_Fake_Client_Name variable value in the Assertion, it will be available (updated) either in the next sampler of during the next iteration of the current sampler:

Also be aware that starting from JMeter 3.1 you're supposed to be using JSR223 Test Elements and Groovy language for scripting so you could change your code to something like:

switch (vars.get('status')) {
    case '500':
        prev.setResponseCodeOK()
        prev.setSuccessful(true)
        vars.put('Api_Fake_Client_Name', 'FAKE_CLIENT_RETRY');
        prev.setSampleLabel('FAKE_CLIENT_RETRY')
        break;
    case 'ERROR':
        prev.setSuccessful(false)
        vars.put('Api_Fake_Client_Name', 'FAKE_CLIENT_CALLBACK_ERROR')
        prev.setSampleLabel('FAKE_CLIENT_CALLBACK_ERROR')
        break;
    default:
        vars.put('Api_Fake_Client_Name', 'FAKE_CLIENT_CALLBACK_SUCESS')
        prev.setSampleLabel('FAKE_CLIENT_CALLBACK_SUCESS')
}
