WAPT is a load, stress and performance testing tool for websites and web-based applications. In contrast to "800-pound gorilla" load testing tools, WAPT is designed to minimize the learning curve and give the user an ability to create a heavy load from a single regular workstation. You can create a basic test scenario and get meaningful information about your performance landscape in a matter of minutes.
WAPT is able to generate up to 2000 simultaneously acting virtual users for an "average" test scenario using standard hardware configuration (Pentium 4/Athlon XP or better CPU, 2 Gb RAM or more, Gigabit Ethernet). WAPT creates a test workload which is virtually the same as the load experienced by a web site in the real world. Virtual users in each profile are fully customizable. They can have individual IP address (IP spoofing), user name and password, and persistent cookies, to name a few.
Basic and Integrated Windows (NTLM) authentication methods are supported. Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process. You don’t need to wait for the completion of the test to get results, so if you have already identified a problem, you can stop the test, fix the problem and start the test again to check for performance changes. The command line interface allows you to integrate WAPT into the existing development environment. Standard XML files are used to store test scenarios and can be modified by third party software.
