'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.
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.
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.
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.
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.
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.
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.
