System.NullReferenceException : Object reference not set to an instance of an object.

[Ferry]

Hi,

 

I'm using VS 2019 Enterprise with Telerik Testing Framework. I'm using examples provided by your support document part 'WPF UI Automation'. I have added ArtOfTest.WebAii in the reference and created a test. But when running the test I keep getting the System.NullReferenceException. Can you help me out?

Hello F J,

Looking at the code, I can't say for sure what is causing the System.NullReferenceException. That said, I noticed that the LaunchNewApplication() method launches the MainWindow.xaml file. This method actually should start the application under test with its .exe file.

Please try using the .exe file of the application and let me know if you encounter the same issue. It will help me greatly, if you can let me know which line of code throws this exception.

Sorry for the late reply. But it was indeed the .exe that fixed the issue
