Load Testing

Applies to TestComplete 15.64, last modified on May 16, 2024

Load testing is a process of putting pre-determined load on an application, a web site, or a service and measuring its response. Load testing will help you understand how your system behaves under different conditions and identify performance bottlenecks. For example, it may help you optimize your Internet retail application to sustain increased visits after a promotional campaign.

The HTTP Load Testing modules that were part of some earlier TestComplete versions are no longer available. SmartBear offers a selection of products for load testing. In this section, learn more about available options.


LoadComplete supports a number of improvements as compared with TestComplete Load Testing modules: easier test creation, more realistic test simulation, “quality of service” settings, built-in support for Rich Internet Applications (Ajax, Flash, Flex, Silverlight), using Amazon EC2 cloud machines, distributed testing, easier request parameterization, built-in test data generators, and more. Record LoadComplete scenarios based on your TestComplete functional web tests and use these scenarios to create load tests for your web application. See Integration With LoadComplete.

LoadComplete licenses limit the number of virtual users that can be simulated concurrently. You can purchase licenses for 250, 500, 1000 virtual users and even more, up to 10,000.

LoadNinja offers a brand new way to create load tests by recording real user actions on a target website or web application.

When simulating tests, LoadNinja creates a number of virtual users. Each of virtual users simulates user actions via a real browser, including the recorded think time and client-side scripts.

Depending on the type of license, LoadNinja supplies from 1000 up to 5000 virtual users.
