I just want to know what is opencsv.jar and why do we use it in jmeter. I tried to find more about it on the internet but could not find a proper answer. Can anyone explain this to me?
As far as I'm aware JMeter doesn't use opencsv.jar anywhere.
CSV Data Set Config is used for test parametrization in order to make test data-driven by loading test data from external CSV files
CSVSaveService is used to dump test results into a CSV file.
Both of them rely on Apache JMeter JOrphan library
