Welcome to this quick JMeter tutorial for basic setup and installation. In this tutorial, we’ll walk you through the required steps to prepare it for load testing.
Mostly, we use JMeter for Performance testing. However, it can be used with Selenium for carrying out automating load testing tasks.
JMeter Tutorial: Step-by-Step Setup and Installation
JMeter is a core Java application that can run on any platform that supports Java. Also, if you would ask for a load testing tool from any seasoned tester, he would recommend JMeter.
It supports a number of operating systems where you can run JMeter to execute the load tests.
Check out the below matrix which lists down the commonly used platforms/OS where you can set up JMeter for load testing tasks.
|JMeter 3.0||Java 7+||Windows 8.x (x86_64), Windows 7 (x86_64), Mac OS 10.9.x (x86_64), Ubuntu 15.x (x86_64)|
|JMeter 2.12||Java 6/7||Windows 8.x (x86_64), Windows 7 (x86_64), Mac OS 10.9.x (x86_64), Ubuntu 14.x (x86_64)|
|JMeter 2.9||Java 6/7||Windows XP (i386), Windows 7 (x86_64), Mac OS 10.9.x (x86_64), Ubuntu 14.x (x86_64)|
For today’s JMeter tutorial, we’ll run the JMeter setup on a Windows 7 machine.
JMeter Tutorial – Run Java Setup
Since JMeter is a desktop-based Java app, it needs a compatible JVM to run. For example, we are going to install JMeter 3.0 on a Windows 7 system. So it’ll require Java 7+.
For a note, if you are planning to build some project, then download the JDK package only. Next, you should check the installed Java version. So open the terminal and run the following command.
C:\Users\jmeter>java -version java version "1.8.0_92" Java(TM) SE Runtime Environment (build 1.8.0_92-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)
Most probably the above command would succeed, but if it fails then try re-installing Java again.
Download JMeter Setup
The most stable version to date is JMeter 3.0. So to download it, click on the below link.
Install JMeter Setup
It’s reasonably easy to install JMeter. You just need to extract the zip file downloaded in the previous step. After unpacking the zip file, you will see a tree layout something like the one shown in the below picture.
Here is a brief checklist of folders that you’ll see after extracting the JMeter zip file.
|<bin>||Holds the script file to launch JMeter.|
|<docs>||Offline reference docs.|
|<extras>||Ant script extensions.|
|<lib>||Holds helper Jar libs for JMeter.|
|<lib/ext>||Contains JMeter protocol libs.|
|<lib/junit>||JUnit lib for JMeter.|
|<printable_docs>||Contains ready to print docs.|
Start JMeter for Load Testing
Following are three ways to launch JMeter.
- Run JMeter in desktop mode.
- Start JMeter in service mode.
- Launch JMeter in console mode.
Go to the <bin> folder and run the <jmeter.bat> script.
For running tests on multiple nodes, you can start JMeter in service or server mode. So one machine works as the master and the other nodes as the slaves. In this manner, you can generate load from multiple JMeter clients.
JMeter provides a <jmeter-server.bat> script under the <bin> folder to start the server.
When you run JMeter in desktop or UI mode, it consumes a lot of the system’s memory. But there is a way to cut down the memory utilization, i.e. by running the JMeter in console mode.
The JMeter tool takes multiple arguments from the command line. Please follow the below syntax to launch JMeter from the console.
jmeter -n -t <loadTest.jmx> -l <log.jtl> -H <127.0.0.1> -P 8080
You can also run the JMeter in the same manner as we did in the above example. But make sure you have the file created from the JMeter in GUI mode.
Otherwise, the above command will return the <could not open loadTest.jmx> error.
In this part of the JMeter tutorial, we’ll give you basic commands to install JMeter on Ubuntu (e.g. 14.04/15), Mac OS X, and CentOS. But please ensure that you’ve Java installed on these systems prior to installing the JMeter.
Please note that you need to run the JMeter installation with the root user. So add <sudo> before running the <apt-get> command.
$ sudo apt-get install jmeter
To install JMeter on Mac, run the below command.
brew install jmeter
To install JMeter along with plugins, use the following command.
brew install jmeter --with-plugins
$ sudo yum install jmeter
