How to pass variable data in JMETER request

How to use CSV data set config in Jmeter for passing varible data in JSON request 

To create real-time scenario we need to pass variable data in request. For this we can use “CSV data set config”. Right click on Thread group > Add> Config Element> CSV Data Set Config

You will see CSV data set config like this 

Now we need to create a CSV from which JMETER variable will pick up value and append in Request.  Create CSV and enter data for variable, Here I am passing address line as variable. ( You can open CSV in notepad ). After each address press TAB and then next line new address  , So JMETER can understand multiple variables 

Update configuration  in “CSV data config set”

Filename:- Complete path where file is stored 

Variable Name:- You can give any name to variable 

Ignore First line:- If you specified Name of variable in data sheet at first line then Make it True else False ( I made false) 

Delimiter: -  We used TAB so will use \t for tab 

Allow Quoted data:- If test data is in quotes then make it true JEMTER will omit quotes and will use data inside quotes (Recommended to keep True always) 

Recycle on EOF: - True, It will recycle used data once reaches to end of file 

Stop Thread on EOF:- False , as we want to recycle data 

Sharing mode: - All threads  

Once CSV data set configuration done we need to replace actual address line with variable name ${addressLine} 

Now run test for 5 users, and check result all 5 users sent different address line in request
