The testing helps QA professionals to identify the maximum
amount of load or pressure an application can withstand. But the testers need
complete the load tests within a stipulated amount of time and controlled lab
conditions to assess the performance of the application accurately under both
normal and peak conditions. That is why; most testers use load testing tools to
assess the performance of the application regularly and repeatedly under varying
loads. They also have option to take advantage of a number of open source load
testing tools to assess the performance of the software regularly without
increasing project overheads.
Understanding 8 Widely Used Open Source Load
Testing Tools
1) The Grinder
Despite being a popular load testing
tool Twins Brian Dozier
Jersey , The Grinder is often described as the Java load testing
tool. It can be used to load test any application with a Java API. But The
Grinder supports major protocols like SOAP, HTTP and REST web services. It
allows testers to write test scripts in Jython or Clojure, while providing
centralized script editing and distribution feature. The users also have option
to use data stored on files and databases Twins Kirby
Puckett Jersey , and generate test data on the fly. So it becomes
easier for them to load test the software based on a variety of
parameters.
2) JMeter
Unlike other load testing tools, JMeter is designed
as a desktop application with a graphical user interface. The Java-based tool
further runs on any platform that supports the programming language. It further
supports major web servers and protocols including HTTP, SOAP Authentic Justin
Morneau Jersey , REST web services, MangoDB, TCP Authentic Rod Carew
Jersey , Mail and LDAP. The testers also have option to enhance
test coverage by integrating JMeter with a number of commonly used build and
continuous integration (CI) tools.
3) Tsung
Tsung is designed as a
distributed load testing tool. It supports most of the commonly used protocols
including HTTP, SOAP, MySQL Authentic Bert
Blyleven Jersey , PostgreSQL, WebDAV and LDAP. Tsung is also
designed with features to assess the performance of IP based clientserver
applications by simulating the behaviour of a large number of users. As the
testers have option to run Tsung on multiple machines, it becomes easier for
them to simulate a large number of virtual users simultaneously.
4)
Gatling
The cross-platform load testing tool is written in Scala. It comes
with a recorder that enables testers to record all user actions and simulate all
probable user actions. So it becomes easier for them load test the applications
by creating many test scenarios. Gatling further allows testers to modify and
customize the test scenarios according to the requirements of the project. At
the same time Authentic Kent Hrbek
Jersey , Gatling also helps testers to generate clear, colourful
and information test reports to facilitate decision making.
5)
Locust
Locust is one of the popular user load testing tools for websites and
web applications. It requires testers to write all test scenarios in Python
programming language. The users also have option to run Locust on single or
multiple machines. So it becomes easier for them to distribute load tests over
several machines, and simulate a large number of users simultaneously. Locust
further makes it easier for testers to generate real-time and relevant test
results by providing an extensible web-based user interface.
6)
DieselTest
DieselTest is actually designed as a regression testing tool. So
it is different from other traditional regression testing tools available in the
market. As it supports only keyboard and mouse driven test scripts Authentic Tony Oliva
Jersey , the scripting support provided by DieselTest is not
powerful. But the testers can Playback the test scripts to assess the
performance of the software by simulating behaviour of real website visitors.
They also have option to generate and analyze real-time test results.
7)
OpenSTA
OpenSTA is popular among testers as a flexible load testing tool. It
enables testers to use and playback recorded scripts to assess the application鈥檚
performance regularly. At the same time, the testers also have option to edit
the convert the recorded macro into a test script, make necessary changes to the
script Authentic Paul
Molitor Jersey , and inject it as a hypertext stream. They can even
use the tool to load test a variety of software applications. But the open
source load testing tool looks dated as it was last updated in 2007.

OpenWebLoad
OpenWebLoad is one of the simple and easy-to-use load testing
tools available in the market. It can be used for assessing the performance of a
web application under various loads. The testers also have option to use a
command line to configure and execute load tests. OpenWebLoad further allows
testers to monitor the impact of load optimization in an instant and realistic
way. However, DieselTest is not being updated at regular intervals like other
tools.
However, it is also important for the testers to pick the right open
source load testing tool according to the nature and needs of the project. In
addition to focusing on key features of various load testing tools Authentic
Harmon Killebrew Jersey , they also need to compare the tools based
on test scenario and infrastructure. They can even consider using multiple tools
to assess the performance of the applications accurately under a variety of
loads.
