QTP - Top 34- Interview Questions


Interview Questions on QTP

1. What are the Features & Benefits of Quick Test Pro(QTP)..?
1. Key word driven testing
2. Suitable for both client server and web based application
3. Vb script as the scriot language
4. Better error handling mechanism5. Excellent data driven testing features
2. Where can I get Quck Test pro(QTP Pro) software.. This is Just for Information purpose Only.
 Introduction to Quick Test Professional 8.0, Computer Based Training: Please find the step to get Quick Test Professional 8.0 CBT Step by Step Tutorial and Evaluation copy of the software. The full CBT is 162 MB. You will have to create account to be able to download evaluation copies of CBT and Software.
3. How to handle the exceptions using recovery scenario manager in Qtp?
You can instruct QTP to recover unexpected events or errors that occurred in your testing environment during test run. Recovery scenario manager provides a wizard that guides you through the defining recovery scenario. Recovery scenario has three steps1. Triggered Events2. Recovery steps3. Post Recovery Test-Run
4. What is the use of Text output value in Qtp?
 Output values enable to view the values that the application talks during run time. When parameterized, the values change for each iteration. Thus by creating output values, we can capture the values that the application takes for each run and output them to the data table.
5. How to use the Object spy in QTP 8.0 version?
 There are two ways to Spy the objects in QTP
1) Thru file toolbar ---In the File Toolbar click on the last toolbar button (an icon showing a person with hat).2) True Object repository Dialog---In Object repository dialog click on the button “object spy..."In the Object spy Dialog click on the button showing hand symbol. The pointer now changes in to a hand symbol and we have to point out the object to scythe state of the objectify at all the object is not visible...or window is minimised then Hold the Ctrl button andactivate the required window to and release the Ctrl button.
6. What is the file extension of the code file & object repository file in QTP?
 File extension of -- Per test object rep: - -- Shared Object Rep: - filename.tsr Code file extension id script.mts

7. Explain the concept of object repository & how QTP recognizes objects?
 Object Repository: displays a tree of all objects in the current component or in the current action or entire test( depending on the object repository mode you selected).we can view or modify the test object description of any test object in the repository or toad new objects to the repository.Quicktest learns the default property values and determines in which test object class itfits.If it is not enough it adds assistive properties, one by one to the description until it hascompiled the unique description.If no assistive properties are available, then it adds aspecial Ordianl identifier such as objects location onthe page or in the source code.
8. What are the properties you would use for identifying a browser & page whenusing descriptive programming ?
 "name" would be another property apart from "title" that we can use.OR We can also use the property "micClass".ex: Browser("micClass:=browser").page("micClass:=page")....
9. What are the different scripting languages you could use when working withQTP ?
 Visual Basic (VB),XML,JavaScript,Java,HTML
10. Give me an example where you have used a COM interface in your QTP project?
 11. Few basic questions on commonly used Excel VBA functions.
 common functions are:Coloring the cellAuto fit cellsetting navigation from link in one cell to other saving
12. Explain the keyword createobject with an example.
 Creates and returns a reference to an Automation objectsyntax: CreateObject(servername.typename [, location])Argumentsservername:Required. The name of the application providing the object.typename : Required. The type or class of the object to create.location : Optional. The name of the network server where the object is to be created.
13. Explain in brief about the QTP Automation Object Model.
 Essentially all configuration and run functionality provided via the QuickTest interface isin some way represented in the QuickTest automation object model via objects, methods,and properties. Although a one-on-one comparison cannot always be made, most dialog boxes in QuickTest have a corresponding automation object, most options in dialog boxescan be set and/or retrieved using the corresponding object property, and most menucommands and other operations have corresponding automation methods. You can use theobjects, methods, and properties exposed by the QuickTest automation object model,along with standard programming elements such as loops and conditional statements todesign your program.
14. How to handle dynamic objects in QTP?
 QTP has a unique feature called Smart Object Identification/recognition. QTP generallyidentifies an object by matching its test object and run time object properties. QTP mayfail to recognise the dynamic objects whose properties change during run time. Hence ithas an option of enabling Smart Identification, wherein it can identify the objects even if their properties changes during run time.Check this out-If QuickTest is unable to find any object that matches the recorded object description, or if it finds more than one object that fits the description, then QuickTest ignores the recordeddescription, and uses the Smart Identification mechanism to try to identify the object.While the Smart Identification mechanism is more complex, it is more flexible, and thus,if configured logically, a Smart Identification definition can probably help QuickTestidentify an object, if it is present, even when the recorded description fails.
The Smart Identification mechanism uses two types of properties:Base filter properties—The most fundamental properties of a particular test object class;those whose values cannot be changed without changing the essence of the original object. For example, if a Web link's tag was changed from to any other value, you couldno longer call it the same object. Optional filter properties—Other properties that can helpidentify objects of a particular class as they are unlikely to change on a regular basis, butwhich can be ignored if they are no longer applicable.
15. What is a Run-Time Data Table? Where can I find and view this table?
 In QTP, there is data table used , which is used at runtime.-In QTP, select the option View->Data tabke.-This is basically an excel file, which is stored in the folder of the test created, its name isDefault.xls by default.
16. How does Parameterization and Data-Driving relate to each other in QTP?
 To datadrive we have to parameterize.i.e. we have to make the constant value as parameter, so that in each iteraration(cycle) it takes a value that is supplied in run-timedatatable. Through parameterization only we can drive a transaction(action) with differentsets of data. You know running the script with the same set of data several times is notsuggestable, & it's also of no use.
17. What is the difference between Call to Action and Copy Action.?
Call to Action : The changes made in Call to Action , will be reflected in the orginalaction( from where the script is called).But where as in Copy Action , the changes made inthe script ,will not effect the original script(Action)
18. Discuss QTP Environment.
 QuickTest Pro environment using the graphical interface and ActiveScreen technologies -A testing process for creating test scripts, relating manual test requirements to automatedverification features - Data driving to use several sets of data using one test script.
19. Explain the concept of how QTP identifies object.
 During recording qtp looks at the object and stores it as test object.For each test object QTlearns a set of default properties called mandatory properties,and look at the rest of theobjects to check whether this properties are enough to uniquely identify the object. Duringtest run,QT searches for the run time obkects that matches with the test object it learnedwhile recording.
20. Differentiate the two Object Repository Types of QTP.
 Object repository is used to store all the objects in the application being tested.2 types of oject repositoy per action and shared. In shared repository only one centralised repositoryfor all the tests. where as in per action.for each test a separate per action repostory iscreated.
21. What the differences are and best practical application of each
 Per Action: For Each Action, one Object Repository is created.Shared : One Object Repository is used by entire application
22. Explain what the difference between Shared Repository and Per_ActionRepository
 Shared Repository: Entire application uses one Object Repository , that similar to GlobalGUI Map file in WinRunner Per Action: For each Action ,one Object Repository is created, like GUI map file per testin WinRunner
23. Have you ever written a compiled module? If yes tell me about some of thefunctions that you wrote.
 I Used the functions for Capturing the dynamic data during runtime. Function used for Capturing Desktop, browser and pages.
24. What projects have you used WinRunner on? Tell me about some of thechallenges that arose and how you handled them.
  pbs :WR fails to identify the object in gui. If there is a non std window obk wr cannotrecognize it ,we use GUI SPY for that to handle such situation.
25. Can you do more than just capture and playback?
 I have done Dynamically capturing the objects during runtime in which no recording, no playback and no use of repository is done AT ALL.-It was done by the windows scripting using the DOM(Document Object Model) of thewindows.
26. How long have you used the product?
27. How to do the scripting. Is there any inbuilt functions in QTP as in QTP-S.Whatz the difference between them? how to handle script issues?
 Yes, there's an in-built functionality called "Step Generator" in Insert->Step->StepGenerator -F7, which will generate the scripts as u enter the appropriate steps.
28. What is the difference between check point and output value.
 I would like to add some stuff to Kalpana's comments.
It is as follows:-An outPut value is a value captured during the test run and entered in the run-time but to aspecified location.EX:-Location in Data Table[Global sheet / local sheet]
29. IF we use batch testing.the result shown for last action that how can i getresult for every action.
u can click on the icon in the tree view to view the result of every action
30. How the exception handling can be done using QTP
 It can be done Using the Recovery Scenario Manager which provides a wizard that gudiesyou through the process of defining a recovery scenario. FYI.. The wizard could beaccesed in QTP> Tools-> Recovery Scenario Manager .......
31. How do you test siebel application using qtp?
 Expecting answer from visitors..
32. How many types of Actions are there in QTP?
 There are three kinds of actions:non-reusable action—an action that can be called only in the test with which it is stored,and can be called only once.reusable action—an action that can be called multiple times by the test with which it isstored (the local test) as well as by other tests.external action—a reusable action stored with another test. External actions are read-onlyin the calling test, but you can choose to use a local, editable copy of the Data Tableinformation for the external action.
33. How do you data drive an external spreadsheet?

34. I want to open a Notepad window without recording a test and I do not want touse System Util.Run command as well How do I do this?
 U can still make the notepad open without using the record or System utility script, just by mentioning the path of the notepad "( i.e., where the notepad.exe is stored in the system)in the "Windows Applications Tab" of the "Record and Run Settings window. Try it out.All the Best
