UFT/QTP – Automation Object Model

An object model is a collection of classes or objects which can controlled by any program. An object model gives a facility to control the functionality of an application programmatically.

The UFT Automation Object Model (AOM) is a set of its classes and interfaces together with their properties, methods and events and their relationships.

Using AOM the functionalities of UFT can be controlled from any other applications/programs by using a scripting or programming language.

The functionalities that can be controlled are listed below but not limited to –

  • Loads all the required add-ins for a test
  • Makes QTP visible while execution
  • Opens the Test using the specified location
  • Associates Function Libraries
  • Specifies the Common Object Sync Time out
  • Start and End Iteration
  • Enable/Disable Smart Identification
  • On Error Settings
  • Data Table Path
  • Recovery Scenario Settings
  • Log Tracking Settings

To create the automation object, we use “CreateObject” function. Once the object has been created, we can access all other objects, methods and properties of the UFT. CreateObject creates and returns the reference to an automation object.
Syntax: CreateObject (Servername.typename [, location])

Below is the example in VBScript for creating the UFT application object and starting UFT in visible mode.

Dim qtApp
Dim qtTest
Set qtApp = CreateObject(“QuickTest.Application”)
If qtApp.launched <> True then
End If
qtApp.Visible = True

we need to set the various parameters for execution of the test case

qtApp.Options.Run.ImageCaptureForTestResults = “OnError”
qtApp.Options.Run.RunMode = “Fast”
qtApp.Options.Run.ViewResults = False

Now we are opening the test, the test can be opened in two mode,  read only or edit mode. Here, we have mentioned the flag as true which opens the test in the read only mode. After opening the code, we create the object for the execution and instructs UFT what needs to be done in case of error. And finally run the test using .Run method

qtApp.Open “C:\Program Files\HP\QuickTest Professional\Tests\Demo”, True
Set qtTest = qtApp.Test
qtTest.Settings.Run.OnError = “NextStep”

After the execution, we have to close the test first and then close the QTP using .quit method. In the end we need to release the object using Set Objectname=nothing.

Set qtTest = Nothing
Set qtApp = Nothing

Generating Automation Scripts

The UFT provides an easy option to generate automation scripts for few settings.

  • Test Setting dialog box (File > Setting )
  • Options dialog box  (Tools > Options > GUI Testing)
  • Object identification dialog box (Tools > Object Identification)

These dialog boxes contain a generate script button which generates an automation script file (.vbs) by just clicking on it as shown below (from test setting File > setting). This file contains the current settings from the corresponding dialog box.


A Sample Code looks like this –

Dim App ‘As Application
Set App = CreateObject(“QuickTest.Application”)
App.Visible = True
App.Test.Settings.Launchers(“Web”).Active = True
App.Test.Settings.Launchers(“Web”).Browser = “IE”
App.Test.Settings.Launchers(“Web”).Address = “www.google.com”
App.Test.Settings.Launchers(“Web”).CloseOnExit = False
App.Test.Settings.Launchers(“Windows Applications”).Active = False
App.Test.Settings.Launchers(“Windows Applications”).Applications.RemoveAll
App.Test.Settings.Launchers(“Windows Applications”).RecordOnQTDescendants = True
App.Test.Settings.Launchers(“Windows Applications”).RecordOnExplorerDescendants = False
App.Test.Settings.Launchers(“Windows Applications”).RecordOnSpecifiedApplications = True
App.Test.Settings.Run.IterationMode = “rngAll”
App.Test.Settings.Run.StartIteration = 1
App.Test.Settings.Run.EndIteration = 1
App.Test.Settings.Run.ObjectSyncTimeOut = 20000
App.Test.Settings.Run.DisableSmartIdentification = False
App.Test.Settings.Run.OnError = “Dialog”
App.Test.Settings.Resources.DataTablePath = “<Default>”
App.Test.Settings.Web.BrowserNavigationTimeout = 60000
App.Test.Settings.Web.ActiveScreenAccess.UserName = “”
App.Test.Settings.Web.ActiveScreenAccess.Password = “”
‘ System Local Monitoring settings
App.Test.Settings.LocalSystemMonitor.Enable = false
‘ Log Tracking settings
With App.Test.Settings.LogTracking
.IncludeInResults = False
.Port = 18081
.IP = “”
.MinTriggerLevel = “ERROR”
.EnableAutoConfig = False
.RecoverConfigAfterRun = False
.ConfigFile = “”
.MinConfigLevel = “WARN”
End With
