Performance Testing with Micro Focus Loadrunner 2022

LoadRunner is a software testing tool from Micro Focus. It is used to test applications, measuring system behavior, and performance under load. LoadRunner can simulate thousands of users concurrently using application software, recording and later analyzing the performance of key components of the application.

LoadRunner simulates user activity by generating messages between application components or by simulating interactions with the user interface such as keypresses or mouse movements. The messages and interactions to be generated are stored in scripts. LoadRunner can generate the scripts by recording them, such as logging HTTP requests between a client web browser and an application’s web server.

Hewlett Packard Enterprise acquired LoadRunner as part of its acquisition of Mercury Interactive in November 2006. In Sept 2016, Hewlett Packard Enterprise announced it is selling its software business, including Mercury products, to Micro Focus. As of 01–Sept–2017, the acquisition was complete.

On Dec 12, 2019, Micro Focus announced newer names for the LoadRunner package and started following CalVer.
