What are pre-processor & post-processor elements?..

Answer / Km Shipra Singh

"Pre-processors" in Apache JMeter are elements that execute before the test starts or before a sampler. They allow modifications of the test such as setting up variables, reading files, etc. Examples include CSV Data Set Config, Random Variable, and JSON Extractor. On the other hand, "Post-processors" execute after the test is completed or after a sampler. They can perform actions like assertions, logging results, saving responses to a file, etc. Examples include Assertion Results, View Result Tree, and Response Assertion.
