Performance Testing Tool


'Performance' defines the degree of success of an application among the customers. Performance is one of the crucial factors among the key parameters of quality assurance activity.

The trend of e-commerce application is on such a pedestal that we simply cannot imagine our lives without its presence. The aim of performance testing is to verify an application’s throughput, load time, recovery from failure, reliability etc. Thus software testers aim to conduct a complete analysis of the state of a system to verify whether its conformance to ‘key performance standards’ are fulfilled.

Think about testing an application, be it any, is it feasible to test the entire application manually? Will it be possible to efficiently cover every functionality and aspect of an application by manual test cases? No, certainly not.

In such a case, a software tester resorts to automation testing. With the vastness of software industry in the present day, there are a number of automation tools available that one can opt for testing a software. Automation tools also cater to the different segments of testing an application – functional, performance, security, load, UI. So in this article we try to portray the different categories of automation tools and explaining the range of functionalities it has to offer.

Performance Testing Tools:

  • webLOAD : WebLoad is an automation tool for performance, load and security tests on a software. This tool integrates native Javascripting that is flexible for expanding the range of usage along with support for all kinds of web protocols, server and network technologies. Using WebLoad, testers can simulate traffic on a website with the help of which they can analyse how the system responds to a certain level of load at any given point of time.
  • LoadComplete:A tool specifically designed for testing load, stress and scalability of e-commerce application. The best part about this tool is that testers need not be well versed with a certain programming skill. The tool lets us work seamlessly with internet applications that involve use of AJAX, asp.net, Java, Flash, Silverlight. LoadComplete is quite an easy and affordable option for automating application testing.
  • Apache JMeter:: An automation tool which is built completely on Java is an open source software which aims at testing functionality and performance. Apache JMeter supports a range of protocols, provides record features, database connectivity and so on.
  • The Grinder: A framework that enables load testing by making implementation of distributed tests easy by integrating multiple load injector machines. One may avail this tool freely under BSD-style-open source license.

    Grinder enables writing test scripts in Jython and Clojure, has support for HTTP web servers, SOAP and REST web services and application servers such as CORBA, RMI, JMS etc.

  • Tsung:Distributed under GNU General Public License, Tsung is an extension of IDX-Tsunami. Tsung is a load testing tool providing cross platform support for all types of protocols and one can test various servers and protocols such as HTTP, WebDAV, SOAP, Postgre SQL, MySQL etc.

    This tool has the power to simulate multiple users at a given point of time. Tsung is based on concurrency-oriented programming language – Erlang, which has various features like performance, scalability and fault-tolerance.

  • LoadRunner:LoadRunner is a product from HP and it is one of the most sought after tool for performing load test. Application under test is simulated with the amount of load that would be in the real scenario.

    A business greatly saves a lot of time and effort in terms of performing distributed load testing, efficiency in handling system’s performance to validate whether it meets required performance specifications, identifying root cause of a problem and so on.

  • NeoLoad :A performance and load testing tool that enables testing an application’s is a Java based load testing tool, and works with a wide variety of operating system platform – Linux, Windows, Solaris and so on. With NeoLoad, testers can verify the endurance capacity of the application under test by simulating a certain amount of load.
  • Rational Performance Tester :A load testing tool developed by IBM Corporation lets the tester create performance tests, execute and analyse the results thereby helping the developers to assess an application’s scalability and reliability.

    This tool requires no coding knowledge in order to test an application, it integrates features like real time reporting, rendering HTML view of web pages, checking user profile specific workload and so on.

  • LoadStorm :This load and performance testing tool enables testing of web applications on cloud. One may generate as much traffic as desired to verify scalability of application under test, testers can create their test plans, criteria and scenario.

    This is quite an inexpensive cloud testing tool which has some of the most sought after features such as least scripting knowledge, replicating the number of users who might be using the system at a given point of time. In addition to all that, the tool facilitates measuring error rates, calculate average response time and reporting such occurrences with the help of charts and graphs.

  • HTTperf:The tool is meant for testing performance of web servers. It is a product of HP and developed by David Mosberger, the tool is a great thing to generate HTTP workloads for assessing server performance.The dimensions in which HTTPperf looks at are – robustness which is to measure the sustenance of the server in case of user traffic overload, support for SSL protocol and extensibility to generate new workloads.

Conclusion:

There has been a tremendous rise in demand for quality software products that are capable of handling day to day transactions and operations of an organisation. Therefore the crux of success of an IT firm in delivering an application is in the fact that it meets the standards defined for a software in terms of its performance, because if it performs well, the deal is half way through.

Choice of a performance tool must thus be based on an application’s functionality, the type of environment it must perform, the target audience for whom the application is intended and so on.
