Complete testing of an application before going live can help address issues before the system is revealed to the public. Issues such as the security of the application, the basic functionality, its accessibility to handicapped users and fully able users, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing. An application performance tool (WAPT) is used to test applications and related interfaces. These tools are used for performance, load and stress testing of applications, servers and other interfaces. WAPT tends to simulate virtual users which will repeat either recorded URLs or specified URL and allows the users to specify number of times or iterations that the virtual users will have to repeat the recorded URLs. By doing so, the tool is useful to check for bottleneck and performance leakage in the application or its been tested.
