What is Performance testing?Performance testing is testing that is

performed, to determine how fast some aspect of a system performs under a particular workload.

Types of Performance TestingLoad TestingA test to measure the performance of a system under a specified level of load.Stress TestingA test in which the load on a system is progressively increased until performance degrades below a specified level. The test finds the maximum load the system can support.Volume TestingA test in which the volume of data in the system is set to a realistic or pre-agreed level. The performance of a system on an empty database is normally better than that on a database with a realistic volume of data.

Performance Testing Process

Maybe your boss, who is a beginner, will ask you

What is JMeter ?The Apache JMeterTM is pure Java open source software, which was first developed by Stefano Mazzocchi of the Apache Software Foundation, designed to load test functional behavior and measure performance. You can use JMeter to analyze and measure the performance of web application or variety of services. Performance testing means testing a web application against heavy load, multiple and concurrent user traffic. JMeter originally is used for testing Web Application or FTP application. Nowadays, it is used for functional test, database server test etc.

Steps to Install JMeterStep 1) Install Java

You can download and install the latest version of Java SE Development Kit.

Step 2) Download Jmeterhttp://jmeter.apache.org/download_jmeter.cgi

Step 3) InstallationInstallation of JMeter is extremely easy and simple. You simply unzip the zip/tar file into the directory where you want JMeter to be installed.

Step 4) Launch JmeterYou can start JMeter in 3 modes: GUI Mode Server Mode Command Line Mode

Start JMeter in GUI Mode

Use JMeter in Linux• Using JMeter in Linux is the same as in Window; you simply

run the following shell script.• Run the script file jmeter (This file has no extension)- run

JMeter (in GUI mode by default).• Run the script file jmeter-server - start JMeter in server

mode (calls JMeter script with appropriate parameters)• jmeter.sh - very basic JMeter script with no JVM options

specified.• mirror-server.sh - runs the JMeter Mirror Server in non-GUI

mode• shutdown.sh - Run the Shutdown client to stop a non-GUI

instance gracefully• stoptest.sh - Run the Shutdown client to stop a non-GUI

instance abruptly
