Stress Testing - LoadRunner

Description

Enterprise applications are inherently complex and their many moving parts can become potential points of failure if not tested prior to deployment.

Mercury LoadRunner is an enterprise-class solution for predicting system behavior and performance. Mercury LoadRunner enables your organization to:

  • Obtain an accurate picture of end-to-end system performance prior to going live.


  • Verify that new or upgraded applications meet specified performance requirements.


  • Identify and eliminate performance bottlenecks during the development lifecycle.
Using minimal hardware resources, Mercury LoadRunner emulates hundreds or thousands of concurrent users to apply production workloads to virtually any client platform or environment. Mercury LoadRunner stresses an application from end to end—applying consistent, measurable, and repeatable loads—then uses the data to identify scalability issues that would impact real users in production. As it drives load against the system, Mercury LoadRunner captures the end-user response times of key business processes and transactions to determine if service-level agreements (SLAs) can be met.

Non-intrusive, real-time performance monitors obtain and display performance data from every tier, server, and system component, and diagnostics probes gather code-level data to isolate bottlenecks at the SQL or method level. This combination of end-user, system-, and code-level visibility dramatically reduces time to problem resolution. After the load test is completed, Mercury LoadRunner’s Analysis engine provides a single view of end-user, system-, and code-level performance data. It includes a patented AutoCorrelation engine to scan all end-user, system, and diagnostics data and provide the top-10 likely causes of system slowdown. This enables users to determine if goals have been met and if not, why not and who owns the problem.

Mercury LoadRunner supports performance testing for the widest range of enterprise environments. It can test web, web services, client-server, legacy, Citrix, Java, .NET, and all ERP/CRM applications including PeopleSoft, Oracle, SAP, and Siebel. Mercury LoadRunner has more than 40 non-intrusive monitors tailored for these systems and provides diagnostics for J2EE, .NET, Siebel, Oracle, and SAP.

Benefits


  • Minimize the risk of deploying systems that do not meet performance requirements.


  • Minimize hardware and software costs by accurately predicting system capacity.


  • Begin intelligent service-level management before go-live.


  • Shorten test cycles to accelerate delivery of high-quality applications.


  • Pinpoint end-user, system-, and code-level bottlenecks rapidly and with ease.


  • Reduce the cost of defects by testing early in the development cycle.


Demo scenario

Scenario steps:

  1. Create a LoadRunner test script for an SAP business process.


  2. Expand user load (run the script)
