What is test object model in QuickTest Professional (QTP) ?

The test object model is a large set of object types or classes that QuickTest uses to represent the objects in your application. Each test object class has a list of properties that can uniquely identify objects of that class and a set of relevant methods that QuickTest can record for it.

A test object is an object that QuickTest creates in the test or component to represent the actual object in your application. QuickTest stores information about the object that will help it identify and check the object during the run session.
A run-time object is the actual object in your Web site or application on which methods are performed during the run session.
When you perform an operation on your application while recording, QuickTest:

? identifies the QuickTest test object class that represents the object on which you performed the operation and creates the appropriate test object
? reads the current value of the object’s properties in your application and stores the list of properties and values with the test object
? chooses a unique name for the object, generally using the value of one of its prominent properties
? records the operation that you performed on the object using the appropriate QuickTest test object method
For example, suppose you click on a Find button with the following HTML source code:

<INPUT TYPE="submit" NAME="Find" VALUE="Find">

QuickTest identifies the object that you clicked as a WebButton test object. It creates a WebButton object with the name Find, and records the following properties and values for the Find WebButton:
It also records that you performed a Click method on the WebButton.
