When Nothing Works Virtual Objects is the weapon to achieve your goal. Many of the times you will find that QTP is not able to recognize an object, even if the object behaves like a standard object. Virtual objects helps in such situation, to be able to identify and run tests.

Virtual object feature in QTP enables us to create and run tests on objects that are not normally recognized by QTP. we can define such objects as virtual objects and map them to standard classes like button, checkbox etc.QuickTest emulates the actions on virtual object during the run session. A virtual object can be defined using the virtual Object Wizard. The wizard prompts you to select the standard object class to which you want to map the virtual object. You then mark the boundaries of the virtual object using a crosshairs pointer. Next, you select a test object as the parent of the virtual object. Finally, you specify a name and a collection for the virtual object. A virtual object collection is a group of virtual objects that is stored in the Virtual Object Manager under a descriptive name. Virrtual Object Manager feature enables us to create and manage virtual objects.
