ABSTRACT: Software testing is a process used to identify the correctness, completeness and quality of developed computer software. Although crucial to software quality and widely deployed by programmer and testers, software testing still remains an art, due to limited understanding of the principles of software. The objective of this research paper is to evaluate and analyze the performance of some testing tools and compare them to determine their effectiveness and reliability, used in software testing. In this research paper, two testing tools: WAPT and NEOLOAD are described, Which are implemented on a web application. WAPT is a load, stress testing tool that provides an easy to use & cost effective way to test any website. Whereas , the NEOLOAD is a tool that measures performance and behavior of the system under load. The performance of these testing tools is evaluated and compared and their results will help in adoption and usage of these tools.

In simple words software testing is an activity Software testing is a process used to to check whether the actual results identify the correctness, completeness match the expected results & to and quality of developed computer ensure that the software system is software. Testing identifies faults, defect free. Software testing is whose removal increases the software important because it represents quality by increasing the software’s approximately 50% of the software potential reliability. development budget for software It includes a set of activities projects is spent on testing. conducted with the intent of finding errors in software so that it could be www.ijltemas.in Page 17

Osama Hamed and to evaluate the performance of some Nedal Kafri proposed a performance specific testing tools and compare testing approach for web based them on the basis of certain attributes. aapplication early in the development In recent years, various tools and process. They compared performance techniques are developed for in terms of response time for two web measurement and evaluation of application architectures.

10. Conclusion and future work

Software testing is both a discipline and a process. It is a separate discipline from software development. In this research, we have referred two testing tools WAPT

and NEOLOAD, because of their individual usage in web testing. After analyzing the performance of these

testing tools, we can conclude that NEOLOAD is the best tool for web www.ijltemas.in Page 22
