Explain the keyword createobject with an example.

Ans) Creates and returns a reference to an Automation object . create object creates handle to the instance of the specified object so that we program can use the methods on the specified object. It is used for implementing Automation(as defined by microsoft).

Explain in brief about the QTP Automation Object Model.

Ans) Essentially all configuration and run functionality provided via the QuickTest interface is in 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 boxes can be set and/or retrieved using the corresponding object property, and most menu commands and other operations have corresponding automation methods.
You can use the objects, methods, and properties exposed by the QuickTest automation object model, along with standard programming elements such as loops and conditional statements to design your program

What are the different scripting languages you could use when working with QTP?

What are the properties you would use for identifying a browser & page when using descriptive programming?

Ans) Title is the property we use.ex: Browser("Title:="xxx").page("Title:="xxxx").....
"Name" would be another property apart from "title" that we can use.
Ex: Browser ("name:="xxx"").page("name:="xxxx"").....

Explain the concept of object repository & how QTP recognises objects?

Ans) 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 to add new objects to the repository.
Quicktest learns the default property values and determines in which test object class it fits. If it is not enough it adds assistive properties, one by one to the description until it has compiled the unique description. If no assistive properties are available, then it adds a special Ordinal identifier such as objects location on the page or in the source code.

What is the file extension of the code file & object repository file in QTP?

1.
Ans) for object repositories file the extension is .tsr
for code file the extension is .vbs
