Quality Assurance
Real-time versatile and stable product is the need of the current business world, in which very huge number of commercial transactions are triggered across the global business sectors.
To fulfil the same, a complementary approach of both Functional and Performance Testing is the most reliable / proven path where this combination will add as a major / primary tool for the IT organizations who are supporting the Global Corporate Business.
Functional testing is one face of Quality Assurance process whereas the desired output will be validated for the given input data.
But whereas the Performance Testing is the other face in which the output is measured w.r.t the response time for the functionally successful business scenarios.
In a nutshell, it is a must to have both Functional & Performance Testing because the Complementary Features of both will act as a tool for the evolution of real time stable product.
INTRODUCTION:
While developing a product (be it on-premise / Client-Server / Cloud), on average it is observed that around 50% of time & cost will be consumed for the Quality Control (QC) and Quality Assurance (QA) activities.
In order to meet the desired quality for a Product, it is required that an elaborated testing approach addressing technical, functional and non-functional needs to be carried out.
In this regard, both Functional & Performance are the major test types that will help to determine the quality of a Product.
Both the testing types complementing in nature so that successful execution and completion of both will provide the needed confidence for the End User to use the Product.
Testing is the primary activity / approach to effectively remove the Defects (Bugs) which gets created/induced during the construction (development) of the product.
Testing can be categorized into different types across various criteria. Primarily, one can make two distinct types in Testing as Functional & Performance based on the nature of testing.
In Functional Testing one will validate the desired functionality, which is a group of Test Cases designed, analysed & executed so that the results will confirm to User expectations / product specifications.
This test will have Input data and Output Results will be validated as per the input.
However, only by having functional testing will not provide the complete efficiency as proper functionality alone cannot hold the stability of the product.
To make Complete testing proof, one need to consider few critical non-functional parameters tested through different type of Testing such as Performance testing which will provide higher efficiency in Testing.
Some of the key factors verified in this testing are, Benchmarking (comparing with a standard accepted by majority), Response time for the given input workload and configuration conditions.
