Calling .Net function on UI test instance in TestComplete

 I have a simple wpf app which has a button that increments a value on clicking. I also have a function that returns the latest value. The default value is 5. I also have a UI test in testcomplete that  clicks the button 3 times (so 8). I need to call the .Net function to get this value and assert it. Below is my test code.



 After some search I figured out the CLRbridge details and implemented it. However, As you can see below, the UI test instance and the instance on which I am claling the function are different. So, the function returns 5.



 My question is, how do I invoke the function from the same instance loaded by testcomplete. Or am I going completely the wrong way for this? I tried both script and UI test with if..then, nothing worked. I have tried both direct instance and calling on the appdomain, both doesnt seem to work.



**NOTE:** *I do understand that I can display the value in a UI control and validate the control. However, i am specifically trying this out for a more complex testing functionality we need in a project.*



    function Test2()

    {

      var Increment;

      Increment = 0;

      //Runs the "TCompTest" tested application.

      TestedApps.TCompTest.Run();

      //Clicks the 'button1' button.

      Aliases.TCompTest.HwndSource_MainWindow.MainWindow.Grid.button1.ClickButton();

      //Clicks the 'button1' button.

      Aliases.TCompTest.HwndSource_MainWindow.MainWindow.Grid.button1.ClickButton();

      //Clicks the 'button1' button.

      Aliases.TCompTest.HwndSource_MainWindow.MainWindow.Grid.button1.ClickButton();

      //Increment = dotNET.Incrementer.Incr1.zctor().IntValue(true);

        

    Increment = dotNET.Incrementer.Incr1.zctor().IntValue(true);

    

    **OR**

    

     Increment = Sys.Process("TCompTest").AppDomain("TCompTest.exe").dotNET.Incrementer.Incr1.zctor().IntValue(true)

        

     // if(Increment == 8)

     // {//Posts an information message to the test log.

      Log.Message(Increment);

    //  }

      //Closes the 'HwndSource_MainWindow' window.

      Aliases.TCompTest.HwndSource_MainWindow.Close();

    }
