WAPT 5.0 is a load and stress testing tool that provides you with an easy-to-use, consistent and cost-effective way of testing web sites, web servers, and intranet applications with web interfaces. You may test and analyze the performance characteristics under various load conditions to find bottlenecks of your web applications. WAPT has a set of features to test web sites with dynamic content and secure HTTPS pages. It provides informative test results through descriptive graphs and reports.

Today thousands of businesses worldwide face the challenge of establishing their web presence - a goal difficult to achieve without efficient web site development and testing tools. Why is load and stress testing is so important? Most performance issues arise only when the server is stressed with a high user load. This means that you should perform load testing to know how many concurrent visitors your site can serve flawlessly. It can be difficult to organize such testing without the help of a group of real users. The right way is to use advanced automatic load and stress testing tools. WAPT can simulate up to several thousands real users to check the performance of your site and find any bottlenecks.

WAPT is designed for Microsoft Windows 98/ME/NT/2000/XP. It is competitively priced and does not require expensive hardware to run. If you have been looking for an easy to use yet powerful web load testing solution, look no further. Download the 30-day trial version and see for yourself.

We provide flexible discount program for volume purchase orders. See Order section for more information. If you happen to have a problem or a question, see our Support section for more information on how to contact us. We will be happy to answer your questions.

All registered users of previous versions may upgrade to WAPT 5.0 free of charge.

WAPT Key Features:
Accurate simulation of real user activity
WAPT uses a number of advanced techniques to simulate real load conditions. This approach is much more efficient than producing stress test by sending many identical requests to the server. WAPT creates a simulation of many different users coming from different IP addresses, each with their own parameters: cookies, input data for various page forms, name and password, connection speed and their own specific path through the site. WAPT can even simulate random time between user clicks to make each virtual user as similar as possible to a human user.

Different types of users in one test
If you want to simulate thousands of users, you do not need to specify separate behavior for each of them. Practice shows that usually site visitors can be divided into certain types, and this approach is used in WAPT. You specify behavior for each type of users and add to the test as many users types as you need.
For example, users of an online shop can be divided into those who browse through the catalog, and those brought to a certain page through a marketing campaign to purchase a specific item. Each type of users has specific path through the site and other customizable parameters. For each type you create a separate profile all this data can be specified. In the test you can use as many virtual users of each type as you need. You can create more profiles to represent users browsing different areas of the site or making specific purchases. This will make your test more accurate.

Testing of dynamic web applications
HTTP requests can include parameters that are specific for each user. The values of such parameters can even be different for different users of the same type and can change throughout the session. For example, the server can send a session variable in the reply to the first request from a new user. This variable is added to the subsequent requests from that user to identify them. You can specify how to use these changing parameters.

Flexible load level definition
You can either choose constant load level for the whole test time or increase the load after specified time intervals during the test. You can specify the overall test time and the number of virtual users for each profile. Overall load also significantly depends on the type of users, so you can change it by introducing new types of users, making them "slow" or "fast".

Testing of HTTPS/SSL content
WAPT supports testing of web sites and applications secured by SSL. You do not need to perform any additional actions and can easily work with HTTPS sites just as you do with any others.

Descriptive test reports and graphs
WAPT displays test results through descriptive reports and graphs. They are available even during the test, so you can monitor key parameters of web application performance on the fly and see how your site responds to the increasing load volume. Summary reports and graphs are useful to determine the presence of any problems in overall performance. Then you can check through more detailed reports down to the level of separate user profiles and pages to find specific bottlenecks. All reports are created in HTML format, so you can easily share them with your colleagues. You can also save test results in MS Excel compatible format. During the test WAPT collects complete test data including server replies to each request. You can use this information to research site behavior in all details.

Other Features
Support of different language encodings
Support of all types of proxy servers: HTTP(S), SOCKS4(5)
Additional command-line interface
Scheduled run option to commence testing at a specified time
Ability to add custom strings to HTTP headers
Support for redirects, including redirects to another server

System requirements:
Microsoft Windows 98/Me/NT/2000/XP/2003
Microsoft Internet Explorer 5.5 or higher
About 5 MB of free disc space for program files and 50-500 MB of free disc space for virtual users' logs and reports

WAPT is able to create up to several thousands of virtual users. However this number significantly depends on your test profiles, network bandwidth, hardware and operating system used on computer where you run WAPT.

Recommended hardware configuration:
Pentium 4 or Athlon XP processor
At least 512MB of RAM
Gigabit Ethernet

Please note that WAPT can not create more than 100 virtual users when installed on Microsoft Windows 98/Me. So we strongly recommend to use WAPT with Microsoft Windows 2000/XP/2003.
