Looping in Jmeter

Why we go for looping ?

    Ø  To avoid the length of scripts

    Ø  To make our scripts re-usable if our flow having repeated actions .

Steps to create loop:

1.Create a counter by using beanShell sampler (Do not use inbuilt counter)

   Add line vars.put(“counter name”,”value”) inside beanShell sampler

       2.Create loop counter and add all transection inside loop counter which you want to do for multiple times

3.Add BeanShell postprocessor at  http sampler which we are going to loop

  > Call counter inside beanShell PostProcessor.This counter we are going to use for dynamic variable     creation

  > Create dynamic variable using counter and store values inside it

 Ex: vars.put(“dynamicVariable”+counter,itemValueToStore)

      >Increment the counter at the end of loop refer above image

4. Create httpSampler by using beanShellPreProcessor to save loop

    Ex: If our transaction is to save 100 loop item then at the time of save we need to create our                       httpsample to replace recorded save transaction httpsampler

 

















 >Inside beanShellPreProcessor call created dynamic variable and save it in another variable

         Ex: newVariable = vars.get(“dynamicVariable”+j); here j value in loop(refer above image)

    >To create name and its value inside httpsampler use below command

         Ex: sampler.addArgument(“Name”,”Value”);
