A software package for automated load testing as SAP, and other systems. HP LoadRunner helps prevent costly performance problems in production, by identifying bottlenecks prior to deployment of a new system or upgrade existing.
HP LoadRunner enables cross-cutting measure performance, diagnose bottlenecks applications and systems, as well as customize them to increase productivity - all using a single control center. Built-in functions load testing, performance testing and stress testing for applications can reduce costs and time required for testing and deployment of new applications and systems in a production environment.
Hewlett Packard LoadRunner consists of three modules: - Module VuGen to create a load testing scripts. It records information about user interaction with the system as a software package that is replicated and reproduced during the test. This module can be installed on any workstation where there is a workplace system under test. - To create the load and parameter monitoring hardware and software configuration of the system in real time using the module Controller. To monitor and the load is physically remote systems in the Controller module, there submodule Load Generator. This allows the testing process to consider the influence of network delays when working with the system from different points. Controller Module manages the running tests on all generators load (Load Generator). - After the end of the test data collected from the module Controller transferred to the module Analysis. It helps to visualize where in the software or hardware complex during testing there were delays (bottlenecks) in processing information, analyzing the main characteristics of the system, producing the so-called "drill down", that is, in more detail and show in detail that it was in the test (what a transaction or a user name) has caused problems. Analysis module can be installed both on the same physical machine as a module Controller, and on a separate computer.
Key capabilities of Hewlett Packard LoadRunner: - Obtaining accurate and complete picture of system performance - Verification of conformity of new or updated applications specified performance requirements - Identifying and removing bottlenecks in the work at the design stage - Reduce the time and stops the production of unsatisfactory performance applications

HP LoadRunner became almost a de facto standard for companies that must ensure high reliability and scalability of applications and for this purpose should have a well-functioning system of testing, which allows to determine in advance how applications will behave under real operating conditions. HP LoadRunner provides an opportunity to test the entire IT infrastructure under the influence of any number of virtual users, emulating the traffic that would be created by real users. Each of the virtual users to make real transaction, and HP LoadRunner while measuring the response time, network latency, and performance of server and application parts, allowing you to identify "bottlenecks" of the system and configure it for maximum productivity.
