Load Runner Q & A Part 1

Load Runner Q & A Part 1

1.Where the LoadRunner will be exactly applicable?

Its mainly applicable for testing the performance of the client and server based applications

2.How the LoadRunner will test the application?

LoadRunner enables us to test our system under controlled and peak load conditions. To generate load LoadRunner runs thousands of virtual users that are distributed over a network. Using a minimum of hardware resources,these virtual users provide consistent,repeatable,and measurable load to exercise our client and server system just as real users would.

3.How to evaluate the performance of a system?

LoadRunner's in-depth reports and graph provide the information that we need to evaluate the performance of our client and server system

4.What are all the compatible platforms which will be used to execute the LoadRunner scripts?

Windows,UNIX

5.What are all the parameters LoadRunner will mainly test?

To load our client and server system, LoadRunner emulates an environment where multiple users work concurrently,while the client and server system is under load, LoadRunner accurately measures and analyze the system performance,and its functionality

6.What kind of applications which will be mainly focused by the performance testing?

Modern client and server architectures are complex. While they provide an unprecedented degree of power and flexibility,these systems are difficult to test. Whereas single user testing focuses primarily on functionality and the user interface of single application,client and server testing focuses on performance and reliability of an entire client and server system.

7.What are the limitations of manual load testing?

? It is expensive,requiring large amount of both personnel and machinery

? It is complicated,especially coordinating and synchronizing multiple users

? It involves a high degree of organization

? The repeatability of the manual tests is limited

8.What are all the main features of LoadRunner?

? LoadRunner reduces the personnel requirements

? LoadRunner reduces the hardware requirements

? The controlling will be accomplished effectively by the controller

? Because LoadRunner tests are fully automated,we can easily repeat them as many times we need

9.What is the purpose of LoadRunner scenarios?

Using LoadRunner,we divide our client and server performance requirements into scenarios. A scenario defines

the events that occur during each testing session.

10.What sort of things will be replaced in scenarios?

In the scenario, LoadRunner replaces human users with virtual users or Vusers. When we run a scenario, Vuser emulate the actions of human users-submitting input into the server.
