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. 11.What is load testing? Testing of application for simultaneous users 12.What does vuser_init action contains? Login procedures 13.What is the main aim of load testing? To calculate the response time 14.What the Vuser script will do while running the scenario? The actions that a Vuser performs during the scenario are described in a Vuser script. When we run a scenario,each Vuser executes a Vuser script. The Vuser script include functions that measure and record the performance of the server during the scenario. 15.What is Transaction time? To measure the performance of the server,we define transactions. Transactions measure the time that it takes for the server to respond to tasks submitted by Vuser. 16.What is Rendezvous points? We can insert Rendezvous points in to Vuser scripts to emulate heavy user load on the server. Rendezvous points instruct multiple Vuser to perform tasks at exactly the same time.

17.What is controller? LoadRunner controller is used to manage and maintain our scenarios. Using the controller ,we can control all the Vusers in a scenario from a single work station. 18.What is Hosts? The host is the machine that executes the Vuser script,enabling the Vuser to emulate the actions of a human user. 19.What is mean by Rendezvous points? A rendezvous point creates intense user load on the server and enables LoadRunner to measure server performance under load 20.What is the need for doing load testing? The factors are: Minimal infrastructure,Reliable,Repeatable,Programmable,Comprehensive,Reusable 21.How to create Vuser Groups in loadrunner? A scenario consists of groups of Vusers which emulate human user interacting with your application. When you run a scenario, the Vusers generate load on the server, and LoadRunner monitors the server and transaction performance 22.Why should we automate the performance testing? Its a discipline that leverages products,people and processes to reduce the risk of application,upgrade or patch deployment. It is about applying production work loads to pre-deployment systems while simultaneously measuring system performance and enduser experience. 23.What are all the things will be considered while doing performance testing? ? Does the application respond quickly enough for the intended users? ? Will the application handle the expected user load and beyond? ? Will the application handle the number of transactions required by the business? ? Is the application stable under expected and unexpected user loads? ? Are we sure that users will have a positive experience on go-live day? 24. What are the LoadRunner components? ? Virtual User Generator ? Controller ? Load Generators

? Analysis ? Launcher 25. What is the LoadRunner testing process? ? Plan load test ? Create Vuser Scripts ? Define Scenario ? Run Scenario ? Analyze results 26.What is remote command launcher? The remote command launcher enables the controller to start applications on the host machine 1. 2. 3. 4.

What criteria would you use to select Web transactions for load testing? Why are virtual users created? Why is it recommended to add verification checks to your all your scenarios? What’s the scenario, where you would want to parameterize a text verification check? 5. Why do you need to parameterize fields in your virtual user script? 6. What are the cases why parameterization is necessary when load testing the Web server and the database server? 7. How can data caching have a negative effect on load testing results? 8. What is usually a good indicator that your virtual user script has dynamic data, which is dependent on the parameterized fields? 9. What are the benefits of creating multiple actions within any virtual user script? 10. What is a Load Test Results Summary Report?
