JSR223 PostProcessor VS BeanShell PostProcessor in JMeter

I would recommend using JSR223 PostProcessor

 

About performance:

In JMeter's official user manual, About reducing resource requirements in Best Practice. There is one suggestion said that "Use the most performing scripting language (see JSR223 section)" , as Beanshell Processfor reduces JMeter's performance.

 

About parse JSON response:

And I found that it is more easy to parse JSON response compared with BeanShell PostProcessor . As JSR223 PostProcessor supports Groovy, this is easy to parse JSON using Groovy, no need to import additional JAR packages.

 

Example One:

?

1 2 3 4 5 6 7

import groovy.json.JsonSlurper   def jsonSlurper = new JsonSlurper(); String response=prev.getResponseDataAsString(); //log.info("response" + response); def object = jsonSlurper.parseText(response); dataAllReady = object.data.dataAllReady;

　　

Example Two:

?

1 2 3 4 5 6 7

import groovy.json.JsonOutput import groovy.json.JsonSlurper   def jsonSlurper = new JsonSlurper(); def response = jsonSlurper.parseText(prev.getResponseDataAsString()); def json = JsonOutput.toJson(response.details[0].outBound[0]); vars.put("json", json);
