java testing jmeter

An Open Source Java application designed to measure performance and load test applications.

By The Apache Software Foundation

What Is It?

Apache JMeter can measure performance and load test static and dynamic web applications.

It can be used to simulate a heavy load on a server, group of servers,
network or object to test its strength or to analyze overall performance under different load types.


Complete portability and 100% Java.

Multi-threading allows concurrent sampling by many threads and
simultaneous sampling of different functions by separate thread groups.


Ability to load and performance test many applications/server/protocol types:


Fully featured Test IDE that allows fast Test Plan recording
(from Browsers or native applications), building and debugging.

Command Line

Command-line mode (Non GUI / headless mode)
to load test from any Java compatible OS (Linux, Windows, Mac OSX, ...)


A complete and ready to present dynamic HTML report

Live reporting
into 3rd party databases like InfluxDB or Graphite


Easy correlation through ability to extract data from most popular response formats,
XML or
any textual format

Highly Extensible Core

The Latest Version

Details of the latest version can be found on the
JMeter Apache Project web site


The following requirements exist for running Apache JMeter:

A fully compliant Java 8 Runtime Environment is required
for Apache JMeter to execute. A JDK with keytool utility is better suited
for Recording HTTPS websites.

Some jars are not included with JMeter.
If required, these should be downloaded and placed in the lib directory
- JDBC - available from the database supplier
- JMS - available from the JMS provider
- Bouncy Castle -
only needed for SMIME Assertion

A Java compiler is not needed since the distribution includes a
precompiled Java binary archive.

Note that a compiler is required to build plugins for Apache JMeter.

Installation Instructions

Note that spaces in directory names can cause problems.

Unpack the binary archive into a suitable directory structure.

Running JMeter

  1. Change to the bin directory

  2. Run the jmeter (Un*x) or jmeter.bat (Windows) file.


For Windows, there are also some other scripts which you can drag-and-drop
a JMX file onto:


The documentation available as of the date of this release is
also included, in HTML format, in the printable_docs directory,
and it may be browsed starting from the file called index.html.

Reporting a bug/enhancement

See Issue Tracking.

Build instructions
Release builds

Unpack the source archive into a suitable directory structure.
Most of the 3rd party library files can be extracted from the binary archive
by unpacking it into the same directory structure.

Any optional jars (see above) should be placed in lib/opt and/or lib.

Jars in lib/opt will be used for building JMeter and running the unit tests,
but won't be used at run-time.

This is useful for testing what happens if the optional jars are not
downloaded by other JMeter users.

If you are behind a proxy, you can set a few build properties in
~/.gradle/gradle.properties for Gradle to use the proxy:


Test builds

JMeter is built using Gradle.

The following command builds and tests JMeter:

./gradlew build

If the system does not have a GUI display then:

./gradlew build -Djava.awt.headless=true

The output artifacts (jars, reports) are placed in the build folder.
For instance, binary artifacts can be found under src/dist/build/distributions.

The following command would compile the application and enable you to run jmeter
from the bin directory.

Note that it completely refreshes lib/ contents,
so it would remove custom plugins should you have them installed.

./gradlew createDist

Alternatively, you could get Gradle to start the GUI:

./gradlew runGui

Developer Information

Building and contributing is explained in details at
building JMeter
and CONTRIBUTING.md. More information on the tasks available for
building JMeter with Gradle is available in gradle.md.
