2. What is Performance testing ?
3. What protocols does Load Runner support ?
8. What is scenario ?
10 . What is vuser script ?
12. What is transaction ?
13. What is rendezvous point.
15. What is LoadRunner controller ?
16. What is Host.
Load testing is to test that if the application works fine with the loads that result from large number of simultaneous users, transactions and to determine whether it can handle peak usage periods.
Timing for both read and update transactions should be gathered to determine whether system functions are being performed in an acceptable time frame. This should be done standalone and then in a multi user environment to determine the effect of multiple transactions on the timing of a single transaction.
Industry standard protocols for example HTTP and ODBC are explicitly supported by LoadRunner. Furthermore any protocol that communicates over a windows socket can be supported.4. What are the reasons why parameterization is necessary when load testing the Web server and the database server.
Parameterization is generally done to test with multiple set of data or records.5. What is Load Runner ?
LoadRunner accurately measure and analysis the system performance and its functionality.6. When Load Runner is used.
When multiple users work concurrently.7. What is the advantage of using Load Runner.
load runner automatically records the performance of the client/server during test. 2-loadrunner checks where performance delays occur network/client delays. 3-loadrunner monitor the network and server resource to help the improve performance.
A scenario defines the events that occur during is testing session. Exam (deposit cash, withdraw money).9. What is the vuser in the scenario.
LoadRunner replace the human user with vuser.
While run a scenario every vuser execute a script that script known as vuser script.11. What the vuser script contain.
The vuser script includes the function that measure and record the performance of the server during the scenario.
Transaction measure the time, which takes for the server to respond to task submitted by the vuser.
To emulate peak load on the server.14. When the rendezvous point is insert.
When multiple vuser to perform tasks at exactly the same time then insert the rendezvous point to emulate the peak load on the server.
Controller is manage and maintain the scenario. using controller you control all the vuser in single work station .
Host is machine which execute the vuser script.17. what are the LoadRunner testing process.
There are 5 steps.
- planning the test.
- creating the vuser script.
- creating the scenario.
- running the scenario.
- analysis the test result.
18. what is planning for the test.
Define the performance testing requirements for example no. of concurrent users, typical business processes and required response time.
19. what do you mean by creating vuser script.
Creating vuser script for emulate the action that virtual user Perform during the scenario execution.
20.what are the process for developing a vuser script.
There are 5 steps for developing a vuser script.
1-recording the vuser script .
2-edit the vuser script.
3-runtime setting .
4-run the vuser script in stand-alone mode.
5-incorporate the vuser script into a LoadRunner scenario.
21. how to create a scenario?
We have to install LoadRunner controller to the host . Then we include list of host(where vuser script execute) then list of vuser script (where vuser run) and then list of vuser that run during the scenario.22. what do you mean by Remote Command Launcher (RCL).
Rcl enables the controller to start the application on the Host machine .
23. what is LoadRunner Agent.
Agent is interface between host machine and controller.
24. how you load a LoadRunner Agent.
Controller instruct the remote command luncher to lunch the Agent .
25. how many types of vuser are available.
There are several type of vuser(GUI ,Database ,RTE(terminal emulator), SAP, DCOME, People soft, java, Baan)
26. what is GUI vuser and on which platform it will run.
GUI vuser operate graphical user interface application and it can run in either the MS-Windows / X-Windows environment .
27. what is MS-windows.
WinRunner used for MS-Window application .
28. what is X-Windows.
X-runner and VX-runner for X-Windows application.
29. What is LoadRunner API function.
Data base vuser do not operate client application. Using LoadRunner API function the database vuser can access the data from the server.
30. How you develop the database vuser script.
Developing the database vuser script either by recording with LoadRunner vuser script generator (VuGen) or by using LoadRunner vuser script template.
31. How many section database vuser script have.
3 section ,written in code that assemble in C, SQL call to the database, written in TSL (test script language).
32. How you enhance the basic script.
By adding control-flow, structure, by inserting transaction point and rendezvous point, adding functions
33. what is run-time-setting.
Run-time-setting include loop.log and timing information.
34. what is stand-alone mode.
To verify that the script runs correctly.
35. what type of function generate and insert by the vugen to the script when you record a script.
1-LR Function.(vuser function) 2- protocol function.
36. what is LR-function.
obtain the information about vuser running in a scenario .
37. what is protocol function.
Obtain the information about the type of vuser.
38. what are the section contain by the vugen while creating a vuser script.
Vugen contain the 3 section .
1-vuser-init
2-action.
3-vuser-end.
39. what is vuser-init section.
Record a log in to the server(vuser initialize loaded).
40. what is action section.
Record the client activity .
41. what is vuser-end section.
Record a log off in to the server (vuser stoped).
42. How vugen create a vuser script.
By recording the activity between client and server.
43. How you edit the script.
While editing the script we have to inserting the transaction point and rendezvous point.
44. what is the LoadRunner start-transaction and its syntax.
It will start the transaction on the script. Syntax. Lr-start-transaction (transaction name).
45. what is the LoadRunner end transaction and its syntax.
It will end the transaction. Syntax. Lr-end-transaction (transaction name, LR-AUTO).
where you insert the rendezvous point.
Rendezvous point insert in to the script to calculate the peak load of the server. Syntax. lr-rendezvous (rendezvous name).
46. what are the element in the LoadRunner controller.
Title bar(name of the scenarion presently working). Menu bar(selecting the various command). Tool bar. Status bar.
47. what are the 5 icons appear in the buttom of the controller windows.
1-host windows(list of machine).
2-script windows(list of all the vuser script)
3-rendezvous windows.
4-transaction windows(display all the transaction) .
5-output window( display error and notification message).
48. what is .lrs.
LoadRunner save the information in a scenario files.
49. what is scenario wizard.
Through scenario wizard we can create a new scenario.
50. what is filtering and sorting.
We can filter the information display only those items that meet the selected criteria(filter box) .exam you can filter vuser only those who are in ready state. Sorting - we can sort all the vuser in the vuser list. In order to their vuser ID(1,2,3,4,5,6,7,8,9).
51. what are the information crating for each host.
1-the status of the host.
2-the platform type of the host(windows/Unix).
3-details of the scenario.
52. how to create a host list for a scenario.
1-install remote command luncher on every machine.
2-add the name of the host to the host lists.
3-set attributes for each host.
4-select which hosts will take part in the scenario.
53. what the host attributes determine
1-the maximum number of vuser that host can run.
2-the initialization quota .
3-the location of the WinRunner configuration file.
4. the location of the file during run-time.
54. How you set maximum number of vuser that a host can run.
We can modify the maximum number of vuser according to the (available resource , the needs of your scenario, LoadRunner license agreements).
