It is 100% pure Java application for load and performance testing. jMeter is designed to cover categories of tests like load, functional, performance, regression, etc., and it requires JDK 5 or higher. This tutorial will give you great understanding on jMeter framework needed to test an enterprise level application to deliver it with robustness and reliability.

Audience

This tutorial is designed for Software Professionals, who are willing to learn jMeter Framework in simple and easy steps. This tutorial will give you great understanding on jMeter Framework concepts, and after completing this tutorial, you will be at intermediate level of expertise from where you can take yourself to higher level of expertise.

Prerequisites

Before proceeding with this tutorial, you should have a basic understanding of Java programming language, text editor and execution of programs, etc., because you are going to use jMeter to handle all levels of Java project testing (regression, functional, load, performance, etc.,), so it will be good if you have knowledge of software development and software testing processes.

Before going into the details of JMeter, let us first understand a few jargons associated with the testing of any application.

• Performance Test − This test sets the best possible performance expectation under a given configuration of infrastructure. It also highlights early in the testing process if any changes need to be made before the application goes into production.
• Load Test − This test is basically used for testing the system under the top load it was designed to operate under.
• Stress Test − This test is an attempt to break the system by overwhelming its resources.
