HP LoadRunner


HP LoadRunner is an automated performance and testing product from Hewlett-Packard for examining system behavior and performance, while generating actual load. HP acquired LoadRunner as part of its acquisition of Mercury Interactive in November 2006. HP LoadRunner can simulate hundreds or 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 is sold as part of the HP IT Management Software category by the HP Software Division.

Consider the client-side application for an automated teller machine (ATM). Although each client is connected to a server, hundreds of ATMs may be open to the public. During peak times — such as 10 a.m. Monday, the start of the work week — the load may be much higher than normal. In order to test such situations, it is not practical to have a test bed of hundreds of ATMs. So, one can use an ATM simulator and a computer system with HP LoadRunner to simulate a large number of users accessing the server simultaneously. Once activities are defined, they are repeatable. After debugging a problem in the application, managers can check whether the problem persists by reproducing the same situation, with the same type of user interaction.

HP LoadRunner consists of several different tools: Virtual User Generator (VuGen), Controller, Load Generator, and Analysis.
Furthermore, LoadRunner supports a very wide variety of application protocols; this allows LoadRunner to natively support many types of applications, including those based on Web technologies, Flex AMF, Citrix ICA, Remote Desktop Protocol (RDP), ERP/CRM (e.g. SAP, Oracle eBusiness, Siebel and PeopleSoft), Databases, Mail Clients, Web Services, and many more. Recently, AJAX Tru Client was introduced (new with V.11.0), that provides LoadRunner with next-gen web application support.
Licensing is based on a number of variables, including the number of concurrent load test users, the number of controllers, as well as the type of protocols utilized.
Additionally, HP Performance Center is available for larger installations; adding central administration, team management and resource pooling capabilities
