HP LoadRunner is an automated performance and test automation product from Hewlett-Packard for application load testing: examining system behaviour and performance, while generating actual load. HP acquired LoadRunner as part of its acquisition of Mercury Interactive in November 2006.
A software testing tool, HP LoadRunner works by creating virtual users who take the place of real users' operating client software, such as Internet Explorer, sending requests using the HTTP protocol to IIS or Apache web servers. HP LoadRunner can simulate thousands of concurrent users to put the application through the rigors of real-life user loads, while collecting information from key infrastructure components (Web servers, database servers etc.) The results can then be analyzed in detail to explore the reasons for particular behavior.
HP LoadRunner supports various protocol bundles for load testing: .NET Record/Replay, Database, DCOM, GUI Virtual Users, Java Record/Replay, Network, Oracle E-Business, Remote Access, Remote Desktop, Rich Internet Applications, SAP, SOA, Web 2.0, Web and Multimedia and Wireless.
