Scrutiny on Various Approaches of Software Performance Testing Tools

Performance testing is vital for all types of systems and applications, especially in critical fields like Medical, Drug discovery systems and Healthcare, and also for Flight control, defense, Automotive etc. which are mission critical. The testing has to be started in the early stages of the product development cycle for better performance and quality. The performance testing tools tests the system or application rigorously before delivering it to customers and its efficiency builds confidence in users so that they always view the statistical results as accurate and genuine. This paper presents a comparison on the commonly used performance testing tools and concepts, and also the methodologies of testing for a variety of existing and emerging applications is explained.
