WAPT Pro is a load and performance testing tool that works for any web site from a simple web service to a customized ERP or CRM solution. Mobile web applications, corporate portals and intranet sites implemented with any technologies can be easily tested with WAPT Pro. The test is created in a matter of minutes by recording it in a browser. A few clicks are required to make thousands virtual users concurrently execute duplicated sessions against your site. A convenient user interface lets you design data-driven tests with help of variables and session-specific values extracted from the server responses. This is done explicitly in the properties of each HTTP request. No scripting is required for the test implementation. Descriptive graphs and reports will let you analyze the performance parameters of the system components under various load conditions. You can isolate and fix any bottlenecks and optimize your software and hardware configuration. WAPT Pro is quite efficient and scalable. While the default configuration is sufficient to run up to 4k concurrent virtual users, you can easily extend it by adding multiple servers connected to a single workplace component. This way you can emulate up to 1M users. All components can be used in any virtual or cloud environment. A special edition is provided through the Amazon EC2, where you can use it at hourly price that depends on the test load volume.
