Interview Questions Part 6

How to Import data from a ".xls" file to Data table during Runtime.
Datatable.Import "...XLS file name..."DataTable.ImportSheet(FileName, SheetSource, SheetDest) DataTable.ImportSheet "C:\name.xls" ,1 ,"name"
 
How to export data present in Datatable to an ".xls" file?
DataTable.Export "....xls file name..."
Syntact for how to call one script from another? and Syntax to call one "Action" in another?
RunAction ActionName, [IterationMode , IterationRange , Parameters]Here the actions becomes reusable on making this call to any Action.IterationRange String Not always required. Indicates the rows for which action iterations will be performed. Valid only when the IterationMode is rngIterations. Enter the row range (i.e. "1-7"), or enter rngAll to run iterations on all rows.If the action called by the RunAction statement includes an ExitAction statement, the RunAction statement can return the value of the ExitAction's RetVal argument.

 
How to export QTP results to an ".xls" file?
By default it creates an "XML" file and displays the results

 
How the exception handling can be done using QTP
It can be done Using the Recovery Scenario Manager which provides a wizard that gudies you through the process of defining a recovery scenario. FYI.. The wizard could be accesed in QTP> Tools-> Recovery Scenario Manager.

 
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 is stored (the local test) as well as by other tests.external action—a reusable action stored with another test. External actions are read-only in the calling test, but you can choose to use a local, editable copy of the Data Table information for the external action.

 
Analyzing the Checpoint results
Standard Checpoint :By adding standard checkpoints to your tests or components, you can compare the expected values of object properties to the object's current values during a run session. If the results do not match, the checkpoint fails.

 
How to handle Run-time errors?
On Error Resume Next : causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of the procedure containing the On Error Resume Next statement. This allows execution to continue despite a run-time error. You can then build the error-handling routine inline within the procedure.Using "Err" object msgbox "Error no: " & " " & Err.Number & " " & Err.description & " " & Err.Source & Err.HelpContext

 
What are the different scripting languages you could use when working with QTP ?
Visual Basic (VB),XML,JavaScript,Java,HTML

 
How to handle dynamic objects in QTP?
QTP has a unique feature called Smart Object Identification/recognition. QTP generally identifies an object by matching its test object and run time object properties. QTP may fail to recognise the dynamic objects whose properties change during run time. Hence it has 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 recorded description, 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 QuickTest identify 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 could no longer call it the same object. Optional filter properties—Other properties that can help identify objects of a particular class as they are unlikely to change on a regular basis, but which can be ignored if they are no longer applicable.

 
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.
