JSR223 PreProcessor is a scripting-based pre-processor. JSR stands for Java Specification Requests. As same as BeanShell PreProcessor which we discussed earlier; you will need to implement the pre-processing logic by yourself using one of the supported scripting languages like Groovy, BeanShell, java, javascript, jexl etc. Usually, it is helpful when you need to write custom code based on some unique algorithm which is not currently provided by JMeter. You can create your own implementation of the code using JSR223 PreProcessor.

What are the attributes of "JSR223 PreProcessor" element?
"JSR PreProcessor" has following attributes:
Next Topic:What are the attributes of "JSR223 PreProcessor" element?
"JSR PreProcessor" has following attributes:
- Name: To provide the name of the preprocessor
- Comments: To provide arbitrary comments (if any)
- Language: To choose scripting language.
- Parameters: Parameters to pass to the script. This is an optional attribute.
- Script file: A file containing the script to run. The return value is the desired output.
- Script compilation caching: Unique String across Test Plan that JMeter will use to cache the result of script compilation if the language used supports Compilable interface (Groovy is one of these, java, BeanShell and javascript are not)
- Script: The manual script which contains the pre-processing logic.
Recommendation: It is recommended to use JSR223 test elements and Groovy as a language for any scripting. Groovy scripting is as fast as Java while BeanShell and JavaScript need to be interpreted, which causes some performance overhead.
