The post processor was attached to a request that came before the request that was actually using the date. If you want to pass a value from JSR223 Test Elements to other JMeter components - the easiest way is writing the value into JMeter Variables using vars shortcut (stands for JMeterVariables class instance). For example, if you have put a sample time out of 400 milliseconds, then all requests which are taking time>400 will have a failed response.Please see below screenshots. The BeanShell postprocessor prints this variable out to the system log, using function print ($ {packNum}). Then start to work with API in Jmeter by using pre-defined variables. ArrayList arr = new ArrayList - creates an object with a raw data type ArrayList arr.add (1) - adds a value to an object log.info (arr.toString ()) - the first arr.toString converts the values of the object into a string, and then log.info prints this value to the JMeter console If the toString method is not implemented in the class on which the object was created, the method simply returns . The code can be downloaded from this link Reading CSV with BeanShell in JMeter manually or see it below: Usually, it is helpful when you need to define think time based on some unique algorithm which is not currently provided by JMeter. How to Work With Strings in JMeter | Blazemeter by Perforce To add the BeanShell PreProcessor to Sampler request: Right Click on the Sampler -> Add -> Pre Processors -> JSR223 PreProcessor To show the JSR223 preprocessor in action we can rewrite the previously created script for a random string creation which we used with BeanShell. Click 'JSR223 PreProcessor'. To create variables in Java language, you can use any standard JMeter element that supports BeanShell. get ("myCookieValue"); // Create a new Cookie and add it to the cookie manager Cookie cookie = new Cookie ("cookieName", cookieValue, "localhost . Just as other preprocessors like RegularExpression and XPath Extractor works, BeanShell PreProcessor makes use of scripting to extract values. You should be able to see that it was assigned in "jp@gc - Parameterized Controller". Pre Processor is being executed before request so variable gets populated. Choose the option from log viewer and open it to view the previous commands. Parameters: Parameters as a String. Follow the below steps to add 'BeanShell PreProcessor': Select the appropriate element where you want to add PreProcessor Test Plan Thread Group Logic Controller Sampler Right-click on the element Hover the mouse on 'Add' Hover the mouse on 'PreProcessor' Click 'BeanShell PreProcessor' Figure 01 It is a loosely typed variable.
