How to Use CSV File for Login Multiple Users through JMeter

Introduction: JMeter is the open source tool and platform independent. JMeter is used for performance and load testing of a web application. Everyone is moved towards the web applications so the load is increasing day by day. Nowadays companies main focused is to give the best user experience to the end users. After developing the applications their main focus in on Load and performance testing. 

When we are performing performance testing with JMeter then we might face the issue of multiple user login with different Id’s.

i) When we record the API's and start load testing on the applications API then 1 user login multiple times in the app. Sometimes it creates a problem.

ii) When we add each page in the JMeter and if we increase the number of the thread count then it is also 1 user comes multiple times in the application.

Prerequisites: JMeter is installed in your system. And you also need to create the file of user inputs which you going to enter in the parameters. In my case, I have only one parameter which "passphrase" so I create a file and save with .csv extension.

Step1: Go to Jmeter and add the Thread Group. As you see in the image I have added the thread group first and give the number of counts is 10 because I have added 10 passphrases in my CSV file. Ramp-up count is 1 and time 1 second.
