QTP AOM and how to write scripts in AOM

by | Last Updated On Oct 21, 2020 | Automation Object Model | 18 comments

What is QuickTest Automation Object Model?

It’s a way to write scripts so as to automate your UFT/QTP operations. For example: Using AOM you can launch UFT without double clicking the desktop icon.

What are some places where we can use AOM in UFT?

This is a small list of places (but not limited to) where we can use AOM. Thumb Rule – Use it at any place where you find yourself doing repetitive tasks while using UFT/QTP.

  • AOM can come handy when you have a large no of scripts to be uploaded to QC. A simple script can save you hours of manual work!
  • Use AOM to initialize QTP options and settings like add-ins etc.
  • You can use AOM to call QTP from other application: For ex: You can write a macro for calling QTP from excel.

Caution: AOM should be used outside of QTP and not within the script (during playback). Though there is no harm using it inside but some of the AOM statements might fail.

How to write AOM scripts?

You need to understand that the very root of QT AOM is Application Object. Every automation script begins with the creation of the QuickTest Application object.

Creating this object does not start UFT. It simply provides an object from which you can access all other objects, methods and properties of the UFT/QTP automation object model.You can create only one instance of the Application object. You do not need to recreate the UFT/QTP Application object even if you start and exit UFT several times during your script.

Once you have defined this object you can then successfully work and perform operations on other objects given in UFT One Automation Object Model Reference.
For ex: Let us connect to ALM using AOM and launch a script qtp_demo

Dim qt_obj 'Define a UFT object
qt_obj = CreateObject("QuickTest.Application") ' Instantiate a QT Object. It does not start QTP.
qt_obj.launch ' Launch UFT
qt_obj.visible ' Make UFT visible
qt_obj.TDConnection.Connect "http://tdserver/tdbin", _ 'Referencing TDConnection Object
"TEST_DOMAIN", "TEST_Project", "Ankur", "Testing", False ' Connect to Quality Center
If qt_obj.TDConnection.IsConnected Then ' If connection is successful
qt_obj.Open "[QualityCenter] Subjecttestsqtp_demo", False ' Open the test
Else
MsgBox "Cannot connect to Quality Center" ' If connection is not successful, display an error message.
End If

To quickly generate an AOM script with the current QTP settings. Use the Properties tab of the Test Settings dialog box (File > Settings) OR the General tab of the Options dialog box (Tools > Options) OR the Object Identification dialog box (Tools > Object Identification). Each contain a Generate Script button. Clicking this button generates an automation script file with extension .vbs containing the current settings from the corresponding dialog box.
You can run the generated script as is to launch UFT/QTP with the exact configuration of the UFT/QTP application that generated the script, or you can copy and paste selected lines from the generated files into your own automation script.

    Hi, I had a question.
    So I have a script which connects to QC and opens a test in UFT and runs it. The problem with this is that the open command closes the previously opened tests. I want to copy the file -> add -> existing test functionality in my vbScript.

    How can this be done?

    Hi Ankur,

    Have a query reg. the AOM. I have written a vbs file to launch qtp, connect to QC, download a specific test from QC, Run the script and update the test results in QC.

    I am successful in saving the test results in a particular test instance under a test set. But this works for the first time.

    When I run the script for the second time, my requirement is to create a second instance and update the test results there.

    Currently, a new run has been created within the first test instance.

    Please guide how to do the same using AOM.

    Thanks in advance!

      can u share how to run a test which is in QC/ALM
      I am getting error – not able to open test. Not sure if the line ObjQTP.Open “[ALM] Components/IHub/IHub Run/TestDD” is correct or not

      Set ObjQTP = CreateObject(“QuickTest.Application”)

      ObjQTP.Launch
      ObjQTP.Visible = “True”

      If Not ObjQTP.TDConnection.IsConnected Then

      ObjQTP.TDConnection.Connect “http://cdlautowfnalm/qcbin/”,”I_HUB”,”Release4_1″,”ginnev”,”vg512013″,False

      End If

      ObjQTP.Open “[ALM] Components/IHub/IHub Run/TestDD”

      Set ObjQTPTest = ObjQTP.Test

      ObjQTPTest.Run

      ObjQTPTest.Close

      ObjQTPTest = Nothing
      ObjQTP = Nothing

    Hi Ankur,

    Thanks for posting the great article. I have one question. How to remove the existing setup and add new setup to a QTP test during Runtime using AOM from with in QTP. Generate script is giving App.Folders.RemoveAll but this line gives error if executed from within QTP.

    Is there any other way of adding by removing the old ones from within QTP? Plese help..

    Thanks In Advance,

    Hi Ankur,

    Thanks a ton for publishing the articles in your block. But I’ll be needing your help in one of the testing with QTP, wherein we are testing for the SAP module- FICO. This is an upgrade activity and we are not using ‘eCatt’ the most likely testing tools by SAP.
    Can you please share your advise on the same, how should we go about it? And how one can identify the reusable Item simply by checking the T-codes.

    Thanks,
    Abhi

    Hi All,
    Tell me please how I can get instance of QTP which it already ran?(inside QTP)
    The main idea is to connect to QC without using QCUtil object.(QCUtil object is using already prepared QCConnection). That is why I’m trying to connect using TDConnection Object.

    Thanks in advance
