Testing The Performance Of The Software Application Is Imperative For Its Release

A software product/application when released into the business market or for the general public, the major concern is about its execution. The society as a whole may confront huge losses if the product/application could not meet the quality of the service needed. In spite of being a functionally rich application, it gets branded as a failed application owing to the failure of its performance expectations. At times it may lead to legal repercussions. Thus a performance test is essential and mandatory before its release to the general public.

Software performance testing verifies that the application meets the predetermined necessities under typical conditions. The testing assures the following for a user.

Speed: The speed of the software must however tally with the general psychology and experience of the user. It must be cost-effective without any hardware, software or network constraints.

Scalability/Adaptability: A general notion or intuition like how many users and how long the software can support; its data base, file server, back-up server and data growth rates, that is its limitation.

Stability/Solidness: It checks the stable performance of the system in adverse/unexpected situations such as an unexpected increase in the number of users, disconnection of users, failure of web server, too many orders, and so on.

Confidence/certainty: It ensures risk assessment and future plans.

Hitherto, performance testing determines the limits of existing systems, make benchmarks for future systems and assess degradation with loads and/or configurations.

There are different types of performance testing. They are as follows:

Load testing – It checks the application’s capacity to perform under anticipated user loads, thereby recognising execution bottlenecks before the software application goes live.

Stress testing – It recognises the limitation of the application. It tests the handling ability of an application under extreme workloads like high traffic or data processing.

Endurance testing – It ensures that the software handle the expected load for a long duration.

Spike testing- It tests the software’s response to abrupt load created by the users.

Volume testing- It monitors the overall software system’s behavior under changing database volumes.

Scalability testing- The goal of adaptability testing is to focus the product application’s adequacy in “scaling up” to support an expansion in user load.

The basic parameters to monitor during the testing process are processor usage, memory use, bandwidth, memory pages/second, hit ratios, hits per second, database locks, thread counts, maximum active sessions, garbage collection, and, etc. Depending on the factors such as types of protocol support, cost of license, platform support, and, etc., one can adapt various tools namely HP Load runner, HTTP Load, Proxy sniffer, and so on.

The software testing company offers a wide variety of testing and quality analysis services. Even though many organizations own the testing services as one of their necessary part, outsourcing may be useful in a manner that, it has a goal-oriented, unbiased testing environment, deploying all the accessible testing practices with ease budget.

Frankly speaking, performance testing assures the life cycle of the application and forms the part of any application development.
