Latest version 2013.1.806.0 Throws System.TypeInitializationException

[Rajchandar]

Hi,

We have been using Telerik Testing Framework for our WPF project. It is working fine with the previous version 2012.2.1420.0.

But today when I upgraded with the latest version 2013.1.806.0, it throws "System.TypeInitializationException" when it is trying find control using automationId (this.WpfWindow.Find.ByAutomationId<T>("automationId"))

Details of the exception thrown are as follows

Exception thrown during the wait for a condition. Error: Unexpected error while waiting on condition. Error: System.TypeInitializationException: The type initializer for 'ArtOfTest.WebAii.Silverlight.ObjectSerializer' threw an exception. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

We have been referring three DLLs in our Project
1. ArtOfTest.WebAii.dll
2. Telerik.WebAii.Controls.Xaml.dll
3. Telerik.WebAii.Controls.Xaml.Wpf.dll

Do we need to refer any additional binaries?

Thanks & Regards,
Raj

The same with my tests. Was working until upgrade...

Hi, I work with Raj who started this post but I have done some further work into this and been able to write a simplified reproduction of this error.
So I have taken down our application to its bare bones and created a simple test project. See attached zip file with project.

The project is purely getting the application running with no interaction with it yet but even though Raj posted an example of when we were attempting to find a control you will see from my example that purely calling Manager.ActiveApplication.MainWindow.RefreshVisualTrees(); causes the same error
To get it running:

1. 1. Replace the exePath With any Wpf Application
2. 2. replace windowsProcessNameOfExe with the process name of your Wpf Application (to help close down duplicate applications).

The Test output for me from executing the test is:

Same problem here (upgraded vom 2012.920).
Seems that a dependency to test studio creeped in?

[Andrea]

I am also having this problem.

Telerik, could you please advise?

[Boyan Boev]

Hello,

Thank you for contacting us. 

Unfortunately I was no able to reproduce this issue on our end. Please send us a sample application with a test project so we can reproduce it in our development environment and give you a proper solution.

Thank you fro your understanding.

I did in fact attach a Test project with my post above and have reproduced it with the simplest of shell wpf applications. Did you try my project? I also assume you are doing this on a machine that does not have Test studio installed?

Can any other posters to this thread try my project and reproduce it with your application? all you should have to change is the application path, the Process name it runs as and a log path (even though its not being output).

        private string exePath = @"C:\Temp\TestSortedView\TestSortedView.exe";

        private static string windowsProcessNameOfExe = "TestSortedView";

        private string logPath = @"C:\Temp\TelerikTestlog";

 

[Max]

Please find attached a wpf application with 1 label of "Hello World!" for you to try it against.

[Andreas]

Analysing the dependency in Reflector shows that Telerik.TestStudio.Interfaces.Communication.ICommunicationRequest and Telerik.TestStudio.Interfaces.Communication.ICommunicationRequestFactory are used.

The former is used in ArtOfTest.WebAii by ArtOfTest.WebAii.Messaging.Http.WcfHttpRawRequest(Factory), the latter is used by ArtOfTest.WebAii.Messaging.Http.WcfHttpRawRequestFactory.

Hope this helps.

[Max]

Has any of the additional information helped you reproduce the problem?

[Boyan Boev]

Hi Max,

Thank you for providing the test and the application. I was able to reproduce this issue and I can confirm that this is a bug. In the new release of our framework we did not install and add in the GAC Telerik.TestStudio.Interfaces.dll.

I have logged a bug report on this issue which you can track here.

I've updated your account with Telerik points. 

We really appreciate when you find bugs and take the time to report them. 

Regards,
Boyan Boev

[Steffen]

Can you provide an internal build with this bugfix, please.

Best regards

[Max]

Seconded

[Boyan Boev]

Hello,

I am attaching Telerik.TestStudio.Interfaces.dll to this ticket.

Please copy it to the bin folder of the framework and install it into the GAC. Here is an article which describes how you can do this. 

If you have Visual Studio installed on your computer: On the taskbar, click Start, click All Programs, click Visual Studio, click Visual Studio Tools, and then click Visual Studio Command Prompt and type gacutil /i path to the dll.

Hope this helps.

Thanks as a workaround this does work.
