Load Testing with Apache JMeter | JMeter Installation

JMeter Installation

JMeter version 1.8 needs JDK1.4 (the JMeter mailing list says that the latest development version, the "nightly build", also works on JDK1.3), and if JDK is on your computer, the installation of JMeter is about the simplest you’d ever experience. First download the JMeter zip file, then unzip it, locate the JMeter.bat file for Windows, or the JMeter file on Unix, and run it. Some of the more advanced features in JMeter, like SSL handling, requires some further installation steps, and they are all described in the User’s Manual.

When JMeter has started you’ll see this Swing client appear on your computer screen:

Building a Test Plan

We’ll now go through the steps of building a "test plan". As web server for all our examples we’ll use Tomcat. The first example is the "Hello World" servlet application that is part of the Tomcat distribution.

Step 1: Start JMeter


Run the JMeter.bat file for Windows or the JMeter file on Unix from the JMeter bin directory.

Step 2: Set the number of simulated users and the number of iterations

You do this by right clicking on the Test Plan node. Then select Add / Thread Group:

On the Thread Group you specify how many users you want to simulate, how fast they’re loaded and how many times you want to repeat the test plan. We’ll repeat the plan 10 times for a single user:

Step 3: Describe the HTTP request (URL and parameters)


This is done by right clicking on the Thread Group node. Then select Add / Sampler / HTTP Request:

The address for the "Hello World" servlet is http://localhost:8080/examples/servlet/HelloWorldExample, and there are no parameters with the request:
