UFT API How to Save a QC/ALM Resource using OTA

UFT API How to Save a QC/ALM Resource using OTA


In a previous post I showed you how to download a QC resource from QTP. Since then I’ve gotten a few request for how to do the same with HP’s Service Test 11.20. Unlike QTP — Service Test does not have an activity like QCUtility that allow you to tap into OTA. But like QTP you can call the OTA API directly. The only difference between the two is that QTP uses VBScript and the ST uses C#. (FYI this functionality is now available in the latest version of UFT API)

How to configure UFT API to use OTA

The first thing you need to do to get OTA to work with ST is to add a reference to it in your script.

  • In ST click on the Test>Add Reference menu option
  • In the Add Reference Dialog click on the COM tab
  • Find and click on ‘OTA COM Type Library’ then click on the Select and OK buttons

OTA Code to Download a QC Resource

Once you have a reference to OTA in your script the next step is to write some custom code.

  • In Service Test under the Toolbox/Miscellaneous folder grab a Custom Code activity and drag it onto the main canvas area.
  • Click on the Custom Code activity and under its property sheet click on the events icon
  • For the Event ExecuteEvent select “Create a default handler..”
  • Under your CodeActivity#_OnExecuteEvent add the following code
  • When you run your script, the resource file should download to your local directory

Hi Joe,

First of all thanks for such a wonderful information.

I am working on assignment to where i have to download folder and it’s sub folders and files inside sub folders for Test Resources tab.

The above code provided by you only donwloads perticular file. It will be great help if you could provide code snippent for downloading folder from QC and it’s content.

Hi Joe,
I am unable to implement Data Driven testing for Service test script in ALM. I have checked the “Allow data driving from ALM/QC” check box in HP Service Test but I couldn’t run my test in
ALM Test plan. please help me on the same.

    Mahesh » Hmm it’s hard to tell without seeing it. Are you getting any error messages? What patch version is your ST?

Hi Joe,

Can you please answer my query on downloading folder and its sub folders and files inside sub folders for Test Resources tab from QC.
The above code provided by you only downloads particular file. It will be great help if you could provide code snippet for downloading folder from QC recursively and it’s content.

Please help me in this!

Hi Joe,

Using the above code, am able to connect to ALM. But get error as;
The type or namespace name ‘QCResourceFactory’ could not be found (are you missing a using directive or an assembly reference?) (CS0246)

Am I missing anything here?


    Joe Colantonio - January 25, 2013

    Prabhu » Before you tried the code are you sure that you added the a reference to the OTA COM Type Library?

Is there a way to do this on Java?

    Joe Colantonio - January 18, 2014

    I’m sure there is but I’ve never done it. Since OTA is a COM DLL you would need some sort of COM to Java bridge.

      When i use the above code i am seeing the below error:-
      Compilation started.
      Warning MSB3245: Could not resolve this reference. Could not locate the assembly “TDAPIOLELib”. Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
      Error MSB3091: Task failed because “AxImp.exe” was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for “AxImp.exe” in the “bin” subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A. You may be able to solve the problem by doing one of the following: 1) Install the Microsoft Windows SDK. 2) Install Visual Studio 2010. 3) Manually set the above registry key to the correct location. 4) Pass the correct location into the “ToolPath” parameter of the task.

Hi Joe,

Thanks for this and I also enjoyed your API testing manifesto. I have followed your steps however I don’t get the option exactly as you have it

TDAPIOLELib.TDConnection qcConn = new TDAPIOLELib.TDConnection();

TDAPIOLELib.TDConnection qcConn = new TDAPIOLELib.TDConnectionClass();

I can log in ok but cannot get passed the line
oResource = (QCResourceFactory)qcConn.QCResourceFactory;

as it throws an error. Any ideas why the TDConnection lines are different

    What version of QC/ALM are you using?
