QTP Miscellaneous Questions

1. If you wish to enter 1234567 in datatable then write it as '1234567

2.Find the palindrome for string - if str1 = strreverse (str1) then -> Palindrome

3. How to capture screenshot - obj.capturebitmap "s:\sd.png",true

4.      Difference between QFL and VBS files – Vbs is executable file. QFL is very specific to QTP and we need to necessarily associate it to Test unlike vbs file which can be included using executefile statement

5.      Difference between Eval and Execute and Executeglobal. Eval will compare while execute will assign value. Executeglobal is used to execute the execute the expression in global scope. These keywords are used to create/include the code at runtime.

6.      Difference between Executefile and loadfunctionlibrary. With executefile, we can’t debug the statements. With loadfunctionlibrary, we can load multiple library files separated by comma and we can debug as well. If you want to debug, you can associate files with action.

7.      Difference between execute and executefile – Same only difference is execute accepts string as argument while executefile uses file as argument.

8.      Difference between invokeapplication and systemutil.run is that invokeapplication is used to launch only .exe application.

9.      MercuryTimers

a.      retTime = MercuryTimers.Timer(TimerName).ElapsedTime ……..Returns the total accumulated time in milliseconds since the timer started. The ElapsedTime property is the default property for the MercuryTimer object.

b.      MercuryTimers("Timer1").Start 'Start measuring time using Timer1.                    Wait 1   MercuryTimers("Timer1").Stop 'After one second, stop Timer1.  'Two seconds later, restart Timer1 (which will continue to measure time from 'the time it stopped). Wait 2 MercuryTimers("Timer1").Continue

10.  What is registeruserfunc? You can use the RegisterUserFunc statement to instruct QuickTest to use your user-defined function as a method of a specified test object class for the duration of a test run, or until you unregister the method. RegisterUserFunc in QTP can be used for both Method Overriding as well as Method Reuse. In method overriding, we can override the default implementation of the function and replace with a new custom implementation. For example, we can create a function, say fnClick, which will not only click on an element, but it also first verify if the element we want to click exists and is enabled. In method reuse, we can create a function which we can bind with multiple controls & then use this function for all these controls. For example, we can create a function fnClick, which can be used to click on a button, on a link on an image and so on.

11.  How can we launch multiple instances of a web application?

Set IE1=CreateObject("InternetExplorer.Application")

IE1.Visible=True

IE1.Navigate "http:\\Yahoomail.com"

Set IE2=CreateObject("InternetExplorer.Application")

IE2.Visible=True

IE2.Navigate "http:\\Rediffmail.com"

12.  e_pwd = Crypt.Encrypt(pwd)

Browser("dfgd").Dialog("pass").WinEdit("pwd").SetSecure e_pwd

13.  sheetcount = DataTable.GetSheetCount

14.  DataTable.Import ("C:\flights.xls")

15.  DataTable.ImportSheet "C:\name.xls" ,1 ,"name"

16.  The following example uses the  SetNextRow method to change the active row to the next row in the run-time Data Table. DataTable.SetNextRow

17.  Browser("Welcome:= Mercury").Page("Welcome:= Mercury").WebEdit(EditDesc).Set "MyName"

18.  DotNetFactory  (System.Environment, System.DateTime, System.Collection)

var_CreateInstance = DotNetFactory.CreateInstance("System.Environment")

msgbox var_CreateInstance.CurrentDirectory

Dim SystemDate , oDate

Set SystemDate = Dotnetfactory.CreateInstance("System.DateTime")

Set oDate = SystemDate.Parse("Fri, 9 Oct 2009")

FormattedDate = oDate.Day & "/" & oDate.Month & "/" & oDate.Year

msgbox FormattedDate

Set SystemDate = Nothing

Set oDate = Nothing                                                                                                                                                                                                                                                             The .NET SortedList class provides a hash table with automatically sorted key/value pairs.

The following code creates a SortedList and populates it with some key/value pairs:

Set objSortedList = Dotnetfactory.CreateInstance ( "System.Collections.Sortedlist" )

objSortedList.Add "First", "Hello"

objSortedList.Add "Second", ","

objSortedList.Add "Third", "world"

objSortedList.Add "Fourth", "!"

For i = 0 To objSortedList.Count - 1

      WScript.Echo objSortedList.GetKey(i) & vbTab & objSortedList.GetByIndex(i)

Next

' this code creates and populates an ArrayList

Set myArrayList = CreateObject( "System.Collections.ArrayList" )

myArrayList.Add "F"

myArrayList.Add "B"

myArrayList.Add "D"

myArrayList.Add "C"

' [1] add the new element to the ArrayList

myArrayList.Add "Z"

' [2] sort the ArrayList

myArrayList.Sort

And how about deleting an element?

In an array you would need to "shift" the elements to fill the gap and then ReDim the array again.

In an ArrayList you would use either myArrayList.Remove "element_value" or myArrayList.RemoveAt "element_index".

19.  Environment.Value("MyVariable")=10

20.  MyValue=Environment.Value("MyVariable")

21.  Extern.Declare micHwnd, "FindWindow", "user32.dll", "FindWindowA", micString, micString …     Enables you to declare calls to external procedures from an external dynamic-link library (DLL).

22.  x=RandomNumber (0,100)

23.  ExitTest - Exits the entire QuickTest test or Quality Center business process test, regardless of the run-time iteration settings. The pass or fail status of the test remains as it was in the step prior to the ExitTest statement.

24.   SystemUtil.Run

SystemUtil.Run ( FileName, Parameters, Path, Operation )

FileName - The name of the file you want to run.

Parameters – For executable file, use the Parameters argument to specify any parameters to be passed to the application.

Path - The default directory of the application or file.

Operation - The action to be performed. If this argument is blank (""), the open operation is performed.The following operations can be specified for the operation argument of the SystemUtil.Run method: Open – Opens files  edit - Launches an editor and opens the document for editing.  explore - Explores the folder specified by the FileName argument. find - Initiates a search starting from the specified folder path. print - Prints the document file specified by the FileName argument.  SystemUtil.Run "D:\My Music\Breathe.mp3","","D:\My Music\Details","open"

oShell.Run Chr(34) & "C:\Program Files\Internet Explorer\IEXPLORE.EXE" & Chr(34)     Set oShell = Nothing

27.   Window("Notepad").WinEdit("Edit").Type micF5

28.  Set WshShell = CreateObject("WScript.Shell")

WshShell.AppActivate "Put the label of the browser" ' Activate the window

wait(3)

WshShell.SendKeys "^f" ' the caret (^) represents the CTRL key.

You can also send special characters such as SHIFT, CTRL, and ALT, which are                             represented by  plus sign (+), the caret (^), and the percent sign (%),

29.   Use Analog or low-level recording when entering keyboard input

30.  Use Mercury Device Replay feature

Set obj = CreateObject("Mercury.DeviceReplay")

Window("Notepad").Activate

obj.PressKey 63   The PressKey method uses the appropriate ASCII or IBM Scan Code value for the key.

31.  Set ssr0XML = XMLUtil.CreateXMLFromFile("D:\temp\XML\ServiceStatus\SSR0.xml")

XMLstr = ssr0XML.ToString

WebService("XOAService_2").SendRequest("ServiceStatus", XMLstr)                        You can retrieve the response to the message sent with this method by inserting a LastResponse statement after it.

32.  How can i check if a parameter exists in DataTable or not?

The best way would be to use the below code:

on error resume next

val=DataTable("ParamName",dtGlobalSheet)

if err.number<> 0 then

33.  How can i check if a checkpoint passes or not?

chk_PassFail = Browser(...).Page(...).WebEdit(...).Check (Checkpoint("Check1"))

if chk_PassFail then

MsgBox "Check Point passed"

else MsgBox "Check Point failed"

end if

34.  What is the difference between an Action and a function?

Action is a thing specific to QTP while functions are a generic thing which is a feature of VB Scripting. Action can have a object repository associated with it while a function can't. A function is just lines of code with some/none parameters and a single return value while an action can have more than one output parameters.

Where to use function or action?

Well answer depends on the scenario. If you want to use the OR feature then you have to go for Action only. If the functionality is not about any automation script i.e. a function like getting a string between to specific characters, now this is something not specific to QTP and can be done on pure VB Script, so this should be done in a function and not an action. Code specific to QTP can also be put into an function using DP. Decision of using function/action depends on what any one would be comfortable using in a given situation.

35.  What are the files and subfolders of a QuickTest Professional test?

The files and folders hold binary and text data that are required for the test to run successfully.

The following table provides a description, the type, and comments regarding the files that make up a QuickTest Professional test.

ü  Test.tsp           -  Test settings Binary

ü  Default.xls       -  Data Table Parameters

ü  Script.mts       -  QTP test script

ü  Resource.mtr - Object Repository

36.  What is the lservrc file in QTP?

The lservrc file contains the license codes that have been installed..The lservrc file contains the license codes that have been installed. Whenever a new license is created, the license code is automatically added to this file. The lservrc file is a text file, with no extension.

37.  How to return array from function?

as a normal variable

38.  Difference between dictionary and array – advantages / disadvantages

ü  The Dictionary object is used to store information in name/value pairs (referred to as key and item). The Dictionary object might seem similar to Arrays, however, the Dictionary object is a more desirable solution to manipulate related data.

ü  Keys are used to identify the items in a Dictionary object

ü  You do not have to call ReDim to change the size of the Dictionary object

ü  When deleting an item from a Dictionary, the remaining items will automatically shift up

ü  Dictionaries cannot be multidimensional, Arrays can

ü  Dictionaries have more built-in functions than Arrays

ü  Dictionaries work better than arrays on accessing random elements frequently

ü  Dictionaries work better than arrays on locating items by their content
