Test Object Model in QTP, is the combination of Test Object 
and Run Object information of the objects used.

QTP tool while recordin captures the objects and its 
current properites in appliction.If U run the script it 
will identifie the  run time object in appliction by  
captured  test object  proprites.

the test object model in qtp is a large set of object types 
or classes that qtp uses to represent the objects in 
application under test.

You can use the QuickTest Professional Automation Object 
Model to write programs that automate your QuickTest 
operations. The QuickTest Automation Object Model provides 
objects, methods, and properties that enable you to control 
QuickTest from another application. 
The new QuickTest Professional Automation Object Model 
enables you to automate test management. 
You can now control virtually every QuickTest feature and 
capability using the objects, methods and properties 
included in the QuickTest Professional Automation Object 
Model. Automation scripts make it easy to perform any 
QuickTest operation multiple times in multiple tests 
without having to open the QuickTest application, for 
example, 
•	You can write a script that modifies the test 
object description properties in the Object Identification 
dialog box and performs an update run on all tests in a 
specified file folder. 
•	After installing a new add-in, an automation script 
can associate this add-in to all relevant tests. 
•	You can write an automation script to run a 
selected batch of tests. For each test, you can retrieve 
the associated add-ins list. Then, if the necessary add-ins 
are not already loaded, you can close QuickTest, load the 
necessary add-ins, reopen QuickTest, and run the test. 
•	You can define your settings for a test in 
QuickTest, then click “Generate Script” in the Generate tab 
of the Test Settings dialog box to generate an automation 
script based on the current test settings. You can then 
apply those same settings automatically to multiple tests 
using the whole automation script or excerpts from the 
generated file. 
Example:
You can create and run an automation program from Microsoft 
Visual Basic that loads the required add-ins for a test, 
starts QuickTest in visible or minimized mode, opens the 
test, configures settings that correspond to those in the 
Options, Test Settings, and Record and Run Settings dialog 
boxes, runs the test, and saves the test. 
Creating automation programs:
The Properties tab of the Test Settings dialog box, the 
General tab of the Options dialog box, and the Object 
Identification dialog box each contain a “Generate Script” 
button. Clicking this button generates a automation script 
file (.vbs) containing the current settings from the 
corresponding dialog box. 
You can run the generated script as is to open QuickTest 
with the exact configuration of the QuickTest application 
that generated the script, or you can copy and paste 
selected lines from the generated files into your own 
automation script. 
Generating an automation script for QuickTest Professional 
options:
1. Go to Tools -> Options.
2. Select the General tab.
3. Click <Generate Script>.
4. Save the script to the desired location.
5. Click <OK> to close the Options dialog. 
Generating an automation script for test settings:
1. Go to Test -> Settings.
2. Select the Properties tab.
3. Click <Generate Script>.
4. Save the script to the desired location.
5. Click <OK> to close the Test Settings dialog. 
Generating an automation script for object identification 
settings:
1. Go to Tools -> Object Identification.
2. Click <Generate Script>.
3. Save the script to the desired location.
4. Click <OK> to close the Object Identification dialog. 
The QuickTest Automation Object Model Reference file is a 
help file that provides detailed descriptions, syntax 
information, and examples for the objects, methods, and 
properties in the QuickTest Automation Object Model. 
When QuickTest Professional 6.5 is installed you can open 
the QuickTest Automation Object Model Reference from: 
•	The QuickTest program folder (Start -> Programs -> 
QuickTest Professional -> Documentation -> Automation 
Object Model Reference) 
•	The QuickTest Help menu (Help -> QuickTest 
Automation Object Model Reference)

Test object model is nothing but qtp will create these
properties to identify the objects on application.
  Which means QTP will create & QTP will use these properties
