So considering the above example, VUGen can record to simulate following business processes: VUGen provides a “recording” feature which records communication to and from client and Server in form of a coded script – also called VUser script. VUGen is used to replicate System Under Load (SUL) behavior.

VUGen or Virtual User Generator is an IDE (Integrated Development Environment) or a rich coding editor. In a real-life situation, these all these 5000 users will not be at homepage but in a different section of the websites. Suppose you are assigned to check the performance of for 5000 users a larger number of users accessing the system at a time as compared to the pastīroadly speaking, the architecture of HP LoadRunner is complex, yet easy to understand.Increased number of simultaneous requests made to the system.Increased number of records present in the database.A number of factors cause decelerating performance, few examples may include:

When a software system is deployed by an organization, it may encounter many scenarios that possibly result in performance latency. It’s estimate that companies lost sales worth $1100 per second due to a recent Amazon Web Service Outage. Only a 5-minute downtime of (19-Aug-13) is estimated to cost the search giant as much as $545,000. Considering the average Fortune 500 company with a minimum of 10,000 employees is paying $56 per hour, the labor part of downtime costs for such an organization would be $896,000 weekly, translating into more than $46 million per year. We’ve examples such as those that recently hit Bank of America Online Banking, Amazon Web Services, Intuit or Blackberry.Īccording to Dunn & Bradstreet, 59% of Fortune 500 companies experience an estimated 1.6 hours of downtime every week. The repercussions of performance downtime are often more devastating than ever imagined. Imagine yourself waiting for 5 seconds when searching for Google or making a friend request on Facebook. In today’s age of Web 2.0, users click away if a website doesn’t respond within 8 seconds. These Virtual Users also termed as VUsers, replicate client’s requests and expect a corresponding response to passing a transaction.Īn estimated loss of 4.4 billion in revenue is recorded annually due to poor web performance. LoadRunner works on a principal of simulating Virtual Users on the subject application.
LoadRunner software is tightly integrated with other HP Tools like Unified Functional Test (QTP) & ALM (Application Lifecycle Management) with empowers you to perform your end to end Testing Processes. You’ll find relief if you’re already using LoadRunner for your performance testing needs. LoadRunner tool has long established a reputation as often you will find clients cross verifying your performance benchmarks using LoadRunner. What is more convincing to pick LoadRunner in software testing is the credibility of this tool.
