QTP/UFT Interview Questions & Answers

QTP Supports 2 types of Object Repository

1) Shared Object Repository (also called Global)

2) Per-Action Object Repository, (also called Local)

Per-Action Object Repository is used by default. The extension for Per-Action repository is “.mtr” .

Shared Object Repository is preferable while dealing with dynamic objects which are called in multiple tests. The extension is “.tsr”

QTP supports the following environments

  • Active X
  • Delphi
  • Java
  • .Net
  • Oracle
  • People Soft
  • Power Builder
  • SAP
  • Siebel
  • Stingray
  • Terminal Emulator
  • Visual Basic
  • Visual Age
  • Web
  • Web Services

Yes.  You can call 4 or even more scripts in your tests.For this, first you will need to make the Actions in the corresponding scripts re-usable.Then from the destination script you can make calls to these re-usable actions.

Action split is to divide an existing action into two parts.The purpose is to divide actions based on their functionality to improve code re-use.

Foremost you will select Java Add – In and launch QTP. Next step record operations on the Java Tree. If you face an issue while recording, you can select Tools > Object Identification > Java, tree object and make changes in mandatory and assistive properties to enable identification.

QTP identifies any GUI Object based on its corresponding properties.  While recording, QTP will identify and store peculiar properties (as defined in the Object Identification settings) in the object repository of the GUI object . At run-time, QTP will compare the stored property values with the on-screen properties, to uniquely identify the GUI object.

QTP supports 3 types of recording modes

1. Normal mode also called Contextual

2. Low-level recording mode

3.Analog mode

Normal Mode: It is the default recording mode and takes full advantage of QTP’s Test Object Model. It recognizes objects regardless of their position on -screen. This is the preferred mode of recoding and is used for most of the automation activities.

Low-level recording mode: This mode records the exact x,y co-ordinates of your mouse operations. It is helpful in testing hashmaps. It is useful for recording objects not identified by normal mode of QTP.

Analog mode: This mode records exact mouse and keyboard “movements” you perform in relation to the screen / application window. This mode is useful for the operation such as drawing a picture, recording signature., drag and drop operations.

We can call an action in 2 ways

1) Call to copy of Action. – In this ,the Action Object Repository , Script and Datable will be copied to the destination Test Script.
2) Call to Existing Action. – In this,  Object Repository , Script and Datable  will NOT be copied but a call (reference) would be made to the Action in the source script.

Your application may contain objects that behave like standard objects but are not recognized by QTP. You can define these objects as virtual objects and map them to standard classes, such as a button or a check box. QTP emulates the user’s action on the virtual object during the run session. In the test results, the virtual object is displayed as though it is a standard class object.

For example, suppose you want to record a test on a Web page containing a bitmap that the user clicks. The bitmap contains several different hyperlink areas, and each area opens a different destination page. When you record a test, the Web site matches the coordinates of the click on the bitmap and opens the destination page.

To enable QTP to click at the required coordinates during a run session, you can define a virtual object for an area of the bitmap, which includes those coordinates, and map it to the button class. When you run a test, QTP clicks the bitmap in the area defined as a virtual object so that the Web site opens the correct destination page.

You will need to create separate Actions which take care of different OS and Browsers

Cross Platform Testing:

Using the Built in Environment Variable you can dig up the OS information.

Eg. Platform = Environment(“OS”). Then based on the Platform you need to call the actions which you recorded on that particular platform.

Cross Browser Testing:

Using this code  Eg. Browser(“Core Values”).GetROProperty(“version”) you can extract the Browser and its correspondin version. Ex: Internet Explorer 6 or Netscape 5. Based on this value you call the actions which are relevant to that browser.

Logical name is a name  given by  QTP while creating an object in the repository to uniquely identify it from other objects in the application. This name would be used by the QTP to map the object name in script with its corresponding description in the object repository. Ex: Browser(“Browser”).Page(“Guru99”) Here Guru99 is the logical name of the object.

Typically ,an object and its properties must be recorded in the Object Repository to enable QTP to perform action s on it.

Using descriptive programming , you do not store the object and its property values in the Object repository but mention the property value pair directly in the script.

The idea behind descriptive programming is not bypass the object repository but help recogonize dynamic objects.

You can use the name property

ex: Browser(“name:=”xxx””).page(“name:=”xxxx””)…..


We can also use the property “micClass”.

ex: Browser(“micClass:=browser”).page(“micClass:=page”)….

Yes .you can record remote application provided you are accessing application through the local browser not via remoter like citrix.

Creates and returns a reference to an Automation object

SYNTAX: CreateObject(servername.typename [, location])


servername: 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.

Yes .We can switch. Go to Test—>Settings—>Resources. Here  you have an option to choose repositories.

Object Spy helps in determining the run & test time object properties & methods of the application under test.

You can access object spy directly from the toolbar or from the Object Repository Dialog Box.

It is very useful during Descriptive Programming

Consider the following –

a) If two objects are overlapped on each other than location based object recognition will fail.

b) If only index based recognition is used your script will work but script execution time will increase.

Hence mandatory and assistive properties are used.

Code file extension is script.mts

QTP Automation Object model deals with Automation of QTP itself. Almost all configuration and functionality provided by QTP is represented by QTP’s Automation Object Model . Almost all dialog boxes in QTP have a corresponding automation object which can set or retrieved using the corresponding properties or methods in the Automation Object Model.QTP Automation Objects can be used along with standard VB programming elements like iterative loops or conditional statements to help you design a script of choice.

Text Output values enable you to capture text appearing on the application under test during run-time.

If parameterized, text output values will capture values appearing in each iteration which would be stored in the run-time data table for further analysis.

Step Generator enables use to Add Test Steps in your script. Using step generator you can add steps to your script without actually recording it.

Test Fusion Report , displays all aspects of a test run and is organized in a Tree format.

It gives details of each step executed for all iterations.

It also gives Run-time data table, Screen shots and movie of the test run if opted.

In QTP Exceptional handling is done by using

a. Recovery Scenarios.
b. Using “On Error” statement

In Recovery scenario you have to define.
1. Triggered Events.
2. Recovery steps.
3. Post Recovery Test-Run.

nvironment variables in QTP are of three types:

1) Built-in (Read only)

2) User-defined Internal (Read only)

3) User-defined External (Read/Write)

You Set the Environment Variable  using the following syntax 

Environment.Value( “name”) = “Guru99”

You can Retrieve the Environment Variable using following syntax

Environment.Value(“name”) — This will retrun name as Guru99

Environment.Value(“OS”)  — This will return your system OS

Image checkpoint does do a pixel to pixel comparison but instead compare image properties like alt text , destination url etc.

Actions have their own Object Repository & Data Table. Actions help make your Test modular and increase reuse. Example: You can divide your script into Actions based on functionality like Login, Logout etc.

Functions is a VB Script programming concept and do not have their own Object Repository or Data Table. Functions help in re-use of your code. Ex:  You can create a Function in your script to concatenate two strings.

Keyword View is an icon based view which shows test steps in tabular format. It also automatically generates documentation for the test steps.

Expert View gives the corresponding VB Script statement for every test step in the Keyword view.

Quick Test testing process consists of 6 main phases:

1)  Create your test plan – This is preparatory phase where you identify the exact test steps, test data and expected results for you automated test. You also identify the environment and system configurations required to create and run your QTP Tests.

2) Recording a session on your application – During this phase , you will execute test steps one by one on your AUT ,and QTP will automatically record corresponding VB script statements for each step performed.

3) Enhancing your test – In this stage you will insert checkpoints , output values , parameterization , programming logic like if…else loops to enhance the logic of your test script.

4) Replay & Debug – After enhancements you will replay the script to check whether its working properly and debug if necessary.

5) Run your Tests – In this phase you will perform the actual execution of your Test Script.

6) Analyzing the test results – Once test run is complete, you will analyze the results in the Test Fusion report generated.

7) Reporting defects – Any incidents identified needs to be reported. If you are using Quality Center , defects can be automatically raised for failed tests in QTP.

The types of Automation Frameworks are –

1) Linear Scripting – Record & Playback

2) The Test Library Architecture Framework.

3)The Data-Driven Testing Framework.

4)The Keyword-Driven or Table-Driven Testing Framework

You can use the Page Checkpoint which gives a count of valid/invalid links on a page.

Data like parameterized output , checkpoint values , output values  are stored in the Run-time Table. It is an xls file which is stored in the Test Results Folder.  It can also be accessed in the Test Fusion Report.

Check point is a verification point that compares a current value for a specified property with the expected value for that property. Based on this comparison, it will generate a PASS or FAIL status.

An output value is a value captured during the test run and can be stored in a specified location like the  Datable or even a variable. Unlike Checkpoints, no PASS/FAIL status is generated.

To connect to the database you must know

a) connection string of your server

b) username

c) password

d) DNS name

You can code the database connectivity command directly or you can use the SQL Query tool provided by QTP.

You can use the Batch testing tool to run multiple scripts. Once the scripts are added in the tool , it  will automatically open the scripts and start executing them one after the other.

As of QTP version 10

1) Huge Tests in QTP consume lots of memory and increase CPU utilization.

2) Since QTP stores results in HTML file (and not txt) the result folder sometimes becomes big.

A step when declared optional is not mandatory to be executed. If the corresponding GUI object is present, QTP performs the operation on it. If the GUI object is not present, QTP bypasses the optional step and proceeds to execute the next step.

Reporter.Reportvent is standard method provided by QTP to send custom messages to the test results window.


Reporter.ReportEvent EventStatus, ReportStepName, Details [, ImageFilePath]


EventStatus = 0 or micPass

1 or micFail

2 or micDone

3 or micWarning

Results can assume any status like Pass , Fail , Warning etc. You can also send screenshot to the test results window.

You declare using a DIM keyword. You assign value to the variable using the SET keyword.


Dim temp ‘Will declare the temp variable

Set  temp = 20 ‘ Will assign a value 20 to temp.

GetRoProperty is a standard method provided by QTP to fetch property values of a run -time object.

Typically, if even one of the on-screen object property does not match the recorded object property. The test fails.

In smart identification, QTP does not give an error if the property values do not match, but uses Base filter and Optional Filter properties to uniquely identify an object. In Smart identification, if a property value does not match the script does not fail but it proceeds ahead to compare the next property. Smart identification can be enabled in Object Identification Dialog box.

We can make use of the “Generate Script” function available in Object Identification, Test Settings and Tools/Options tab to create a zip of the script at the source computer. These zip files then can be imported into QTP at the destination computer.

No. You can work with only single instance of QTP on the same machine. But QTP itself can work on multiple instances of the Application Under Test (AUT). Ex:  QTP can handle multiple IE browser windows.

DataTable.ImportSheet “..\..\TestData\Input.xls”,1,dtGlobalSheet

DataTable.ExportSheet “..\..\Results\Output.xls”,”Global”

SetToProperty changes property of an object stored in the Object Repository. However these changes are not permanent.

The standard delay is 60 seconds. This is can be changed in Test Settigns.

It is an in-built tool provided by QTP to convert Actions into Business Process Components.

a)      qfl is quick test function library file while vbs is Microsoft’s vbscript

b)      qfl is a non-executable file while vbs is an executable file

c)       To use file in UFT associate qfl file from test setting, while to include vbs file use “execute file statement”

The example demonstrated here explains how to read registry key in UFT

‘Create a shell object

Set MyShell= CreateObject (“WScript.Shell”)

Read the value of key from the registry

RegValue =MyShell.RegRead (varpathofkey)

‘in above function we have to pass the path of key in registery’.

e.g. HKCU\software\ie\settings

msgbox RegValue

There are three ways to get system environment variables in UFT

Use the WSH shell object

  • Use WMI’s Win32_Environment Class
  • Read variables from the registry
Set myShell = CreateObject (“WScript.Shell”)

WScript.Echo myShell.ExpandEnvironmentStrings( "%PATHEXT%" )


The output will be .BAT;.CMD;.VBS;. VBE;. JS;. JSE

Other user variable, like TEMP, overwrite their system counterpart

Set myShell = CreateObject( "WScript.Shell" )

WScript.Echo myShell.ExpandEnvironmentStrings( "TEMP=%TEMP%" )


The output will be TEMP:C:\DOCUME~1\You\LOCALS~1\Temp

To send mail from outlook in UFT,

Set Outlook = CreateObject ("Outlook.Application")
Dim Message 'As Outlook.MailItem
Set Message = Outlook.CreateItem(olMailItem)
With Message
.Subject = Subject
.HTMLBody = TextBody
.Recipients.Add (aTo)
Const olOriginator = 0
End With

To fetch data from database in UFT, you have to follow the code below

Set db= createobject (“ADODB.Connection”)
db.Open “Provider=Microsoft.Jet.OLEDB.4.0;Data Source=G:\guru99\vb6\admission_project.mdb;
Persist Security Info= False”
Set rst=createobject(“ADODB.Recordset”)
rst.Open “select*from Course”, db, 3
id=rst. RecordCount
For i=0 to id-1
Print rst.field (0) & rst.fields (1) & rst.fields (2) & rst.fields (3)

To get ftp files from ftp server, you have to use below code

a)      put- To store single file on server

b)      get- To download single file from ftp server

c)       mget- To download multiple files from server

d)      mput- To store multiple files on server

e)      delete- To delete files on ftp server

MyShell.Run "%comspec% /c FTP -n -s:" & commandstoworkwithftp & " " & Site, 0,True

To prevent system getting locked, any of the two ways can be used

  • Create a simple vbs file having code to press numlock key and run that vbs file
  • Edit one registry key “DisableLockWorkstation =1” to disable locking

Descriptive programming includes property name and property value.  Whenever UFT is facing difficulty in identifying objects from object repository, and instead the object is directly identified from the script is known as descriptive programming.

To write data to text file in UFT code is

Content = “Guru99 Rocks”
Set Fo = createobject ("Scripting.FilesystemObject")
Set f = Fo.openTextFile ("c:\myFile.txt",8,true)     ' open in write mode
f.Write (contents)
Set f = nothing

Code to write data to Excel file in UFT is

filepath = “C:\Bugs\Reports.xlsx”
Set objExcel = CreateObject(“Excel.Application”)
objExcel.Visible= True
Set Wb= objExcel.Workbooks.Open (filepath)
Wb.worksheets(1).Cells(1,1).Value = “guru99” read value from Excel file

TSR means Test Shared Repository, it is created to share object repository.

To create TSR file, follow the steps

  • Open object repository
  • Go to file menu
  • Go to export local objects option and select it

After that, UFT will ask you to store .tsr file. Give the path and save.  This will create .tsr file in UFT

To connect with QC, UFT provides the option to connect QC directly from UFT GUI.

a)      Go to file menu

b)      Select (QC) quality center

c)       You will be asked to – Enter QC url

d)      Enter user id, password and project

Following above steps will allow you to connect with QC, later on you can execute the tests from QC itself.

In order to ease the process of test automation using UFT, test automation is designed.  There are mainly three types of automation frameworks in UFT

  • Keyword Driven Framework: It is used when multiple functionality needs to be tested.
  • Data Driven Framework: It is used to test same flow with different test data, test data is given more importance than multiple functionality of application
  • Hybrid Framework: It is a combination of data driven framework and keyword.

Either through object repository or description programming, UFT identifies objects.  Descriptive programming is used in following scenarios

a)      It is used to remove duplicate objects.  Same objects exists in different screens or windows of your application.  If you use OR in this case you have to store same object under different object hierarchy in OR.  To deal with such situation, descriptive programming is used

b)      It is not appropriate in certain scenarios to store the objects inside OR (Object Repository).  Suppose if you want to print 100 links on the page, you should not store all links in OR. Instead you should use Description Programming to access those links.

Settoproperty stands for set test object property.  You can use this property to change the object values at runtime.  You can edit the property values during the runtime, but the changes that are made are temporary.

We can create an array of dictionary using syntax

Dim ArrayofDictionary(2)
First element of array
Set ArrayofDictionary(0)= createobject("scripting.dictionary")
ArrayofDictionary(0).Add "key1", "temp1"
ArrayofDictionary(0).Add "key2", "temp2"
Added keys in first dictionary
Second element of array as dictionary
Set ArrayofDictionary(1)= createobject("scripting.dictionary")
ArrayofDictionary(1).Add "key1", "temp1"
ArrayofDictionary(1).Add "key2", "temp2"
Added keys in second dictionary…..and so on
                               Array                        Dictionary
  • Dynamic array is possible
  • There is no concept of dynamic dictionary
  • Size of array must be set before the use of array
  • The size of dictionary do not need to be set
  • We have to use redim statement before adding extra element into dynamic array
  • To add extra element there is no need to write any statement.  We just use add method
  • There is no particular method to release the memory if particular element is not required
  • Element which is not required any longer can be removed from the dictionary

Round function in UFT is used to round the decimal For example

Mydecimal = 6.3433333
Roundedvalue= Round(Mydecimal , 3)
Print roundedvalue,  it will print 6.343

There are three ways which we can find the count of rows in the table in UFT

a)  Using rowcount property of UFT webtable object

b)  Using GetROProperty of UFT

c)   Using HTML DOM + UFT

steps will create excel file in UFT,

'Create a new Microsoft Excel object
Set myExcel = createobject("excel.application")
'To make Excel visible
myExcel.Application.Visible = true
MyExcel.worksheets(1).Cells(1,1). Value = “Scenario Id”
MyExcel.worksheets(1).Cells(1,2).Value = “Scenario Name”
MyExcel.worksheets(1).Columns(1).ColumnWidth = 10
MyExcel.worksheets(1).Columns(2).ColumnWidth = 40
MyExcel.worksheets(1).Columns(3).ColumnWidth = 20
MyExcel.worksheets(1).Columns(4).ColumnWidth = 20
MyExcel.SaveAs "c:\guru99.xlsx"
blnFlag = False

To export data-table to excel, there are two methods.

a)      DataTable.Export (“C:\export.xls”)

b)      DataTable.ExportSheet “C:\mysheet.xls”   ( If excel file does not exist, new file is created)

To read a value from the cell, we follow 2 step process

a)      We set the row pointer in first step

b)      In second step we define the parameter/column name from the sheet to read


For this example, we have set the row pointer to 2 in transaction sheet


There are 3 loops available in UFT

a)      Do…..Loop : Do Loop will run a block of statements repeatedly

b)      For…..Next : For Next Loop will execute a series of statements until a specific counter value

c)       For……Each : In order to execute a series of statements for each statements for each object in collection “For Each Loop” is used

While….Wend Loop : While Wend Loop is used to execute a series of statements as long as given condition is true

There are three types of error that one will face in UFT

a)      Syntax Errors

b)      Logical Errors

c)       Runtime Errors

There are various ways to handle run time errors

a)      Using test settings

b)      Using on error statement

c)       Using err Object

d)      Using Exit Statement

e)      Recovery Scenarios

f)       Report Object

Exitaction is used when we want to exit from a particular action, while exititeration is used to exit from a particular action iteration of an action.

You can use replace function to remove spaces from string in QTP

Print replace(“ sdsd  sd sd s “, “ “,”””)

Output will be sdsdsdsds

Itrim function can be used if only leading spaces from string needs to be removed

Print Itrim(“ sdsd sd s   “) à Output will be “sdsd sd s”

You can use rtrim function to remove trailing spaces from string

Print rtrim(“ sdsd sd s   ” )  à Output will be “  sdsd sd s”

Code to get the last character of a string in QTP

print right( “junior,1) ‘ à Output will be “r”

There are 4 ways through which we can add synchronisation points in QTP

a)      Wait statement :  This statement will pause the execution for x seconds until object comes up

b)      Wait property : This method will wait until property of object takes particular value

c)       Exist statement : This statement will wait until object becomes available

d)      Sync method: The code will wait until browser page is completely loaded. For web application testing this method is used.

Crypt object in QTP is used to encrypt a strings.



Example :

In this example, value in pwd variable is encrypted using the Crypt. Encrypt method.

Then this encrypted value is entered into editbox.

pwd= “myvalue”
pwd = Crypt.Encrypt (pwd)
Browser(“myb”).WinEdit (“pwd”). SetSecure pwd

In execute file, we can’t debug the statements.  With loadfunction library, statements can be debug and can also load multiple library files.

The code to find the length of array in QTP is

print (ubound(arr)+1)

Ubound returns the last index in array- so length of array will be +1. This will be total number of elements in array

QTP supports 3 types of recording modes

a)      Normal mode : It is the default recording mode and used for most of the automation activities. Regardless of their position on screen it recognizes objects.

b)      Low level recording mode:  It is useful for recording objects not identified by normal mode of QTP. It records the exact x,y coordinates of your mouse operations.

c)       Analog mode: This mode is useful for the operation such as recording signature, drawing a picture, drag and drop operation.

There are two ways you can call from one action to another action

a)      Call to copy of action:  In this,  the script and data-table, action object repository will be copied to the destination Test Script

b)      Call to existing Action: In this, script data-table and object repository are not copied instead a call reference would be made to the action in the source script

When running a test, it test fails in opening a dialog box, QTP does not necessarily abort the test run.  It bye passes any step designated “optional” and continues running the test.  By default QTP automatically marks as optional steps that open certain dialog boxes. In order to set an optional step in the keyword, right click and select “Optional Step”.  The icon for optional step would be added in next step. In the expert view to add optional step, add optional step to the beginning of the VBScript statement.

Array can be defined in 3 ways in QTP

a)      Fixed size array in QTP

Dim A (10) – single dimension

Dim MyTable (5,10) – multi-dimension

b)      Dynamic array-size not fixed

Dim MyArray()ReDim MyArray(25)

c)       Using Array Function in QTP

A= Array (10, 20,30)

B= A(2) ‘ B is now 30

Content = “Guru99”
Set Fo = createobject(“Scripting.FilesystemObject”)
Set f =Fo.openTextFile(“c:\abc.txt”, 8,true)
f.Write (contents)
Set f= nothing

To specify that all variable must be declared before use in QTP,  ‘Option Explicit’ keyword is used.

You must use “Exit For” statement to exit “for loop” in QTP. “Exit For” statement will get the control out of the “for loop”

For count= 1 to 3
TempNum= mid(Tempstr,count,1)
If isnumeric(TempNum) Then
LenghtNum = LengthNum & TempNum
Exit For
End If
GetStrLenNumber = LengthNum

Size of an array in QTP will be found by using the following code Print (ubound(arr)+1)

Ubound returns the last index in array- so size of array will be +1

91) In QTP, explain what is qrs file?

qrs means “Quicktest Recovery Scenario”. By using recovery scenario manager we can handle exceptions in test execution.In QTP using recovery scenario manager we can handle exceptions in test execution. In QTP when you create a recovery scenario, you must save it in .qrs file. qrs file may have any number of scenarios defined in it.

“Action 0” is created by default when you create a new test in QTP along with action 1.  To determine the sequence in which we call other actions 1,2,3 etc. action 0 is used.

To replace part of string in QTP we will use the code as shown below Example,

Str = (Guru99)
Suppose if you want to replace “99” with “88” then the code will
print replace(str,“99”, “88”) output will be “Guru88”

Various types of automation frameworks available in QTP are

a)      Linear Scripting

b)      The Test Library Architecture Framework

c)       The Data Driven Testing Framework

d)      The Keyword Driven or Table Driven Testing Framework

e)      The Hybrid Test Automation Framework

‘Object Spy’ is a feature in QTP by using which you can view both the test and run time object properties and methods.

“GetROProperty” is an in built method used to retrieve runtime value of an object property.

To use GetRoProperty it involves four steps

a)      Record the object on which you want to use the GetROProperty in Object Repository

b)      Identify the run time property for the recorded object which could be used

c)       To retrieve the identified run time property and store the value in a variable

d)      Use this value for further deductions

To find out the absolute value of a number a built in function in QTP is available

Example-   a= -1
Print abs(a) ‘output will be 1

This code will find the absolute value of a number

To check whether if parameter exists in data table we will use the code

on error resume next
val=DataTable(“ParamName”, dtGlobalSheet)
if err.number<>0 then
‘Parameter does not exist’
‘Parameter exists
end if

In keyword driven automation framework, the focus is mainly on keywords/functions and not the test data.  It means the complete focus is on creating functions which maps the functionality of the application.

Xpath can be used to identify only web objects. We can use the following code to identify objects.

Set oPage=Browser(“myGoogle”).Page(“myGoogle”)
oPage.WebEdit(“xpath:=//INPUT[@name=‘nameofeditbox’]”).Set “search term”
‘Enter value in google edit box

To delete excel file in QTP,

Set fo = createobject(“Scripting.filesystemobject”)


Set fo=nothing

Bitmap checkpoints are affected by screen resolution and image size.
