Hi I am using Telerik Testing Framework and while launching a WPF application I am encountering an exception

Test Name: TestMethod1
Test FullName: TestStudioProject1.UnitTest1.TestMethod1
Test Source: C:\Imran\Code\Emdat\Inscribe-CUIT-automation\CodedUITest_TelerikEditor\TestStudioProject1\UnitTest1.cs : line 23
Test Outcome: Failed
Test Duration: 0:00:07.5626828

Result StackTrace:

   at ArtOfTest.WebAii.Wpf.WpfWindow.ConnectToWindow(IntPtr handle, String pipename, String pid)

   at TestStudioProject1.UnitTest1.TestMethod1() in C:\Imran\Code\Emdat\Inscribe-CUIT-automation\CodedUITest_TelerikEditor\TestStudioProject1\UnitTest1.cs:line 25
Result Message:
Test method TestStudioProject1.UnitTest1.TestMethod1 threw exception: 
System.NullReferenceException: Object reference not set to an instance of an object.

 

The code is

public void TestMethod1()
        {
            Manager manager = new Manager(true);
            WpfApplication wpfApplication = manager.LaunchNewApplication(@"C:\TelerikWpfApp2\TelerikWpfApp1\bin\Debug\TelerikWpfApp1.exe");
            var richtextbox = wpfApplication.MainWindow.Find.ByAutomationId<ArtOfTest.WebAii.Controls.Xaml.Wpf.RichTextBox>("radRichTextBox");
        }

 

Let me know am I missing anything here!!!

 

Thanks,

Imran

Hello Imran,

Thank you for reaching us out. 

Could you please let me know some further details for the environment you are running the unit test on - Windows OS version, Visual Studio version, etc? Which of the shared lines of code is line 25 in your solution? Are you executing the test explicitly as administrator? 

I am looking forward to hearing back from you. Thanks in advance!
