Function evaluation disabled error on debugging test project

[Arooj]

Hi,

I'm trying to evalute the Telerik testing framework for silverlight automation.I'm running into a few issues.
Following is the sample code that I am using.

Settings settings = GetSettings();
settings.Web.DefaultBrowser = BrowserType.InternetExplorer;
settings.Web.EnableSilverlight = true;

Initialize(settings, new TestContextWriteLine(this.TestContext.WriteLine));

Manager.LaunchNewBrowser();
ActiveBrowser.NavigateTo("http://localhost/TestSLAppTestPage.html");
ActiveBrowser.WaitUntilReady();

var slApp = ActiveBrowser.SilverlightApps()[0];
Assert.IsNotNull(slApp);

var button = slApp.FindName<Button>("button1");
Assert.IsTrue(button.Text.Equals("Click Me"));

 

When I run this test it passes but I am unable to debug it. When I put a breakpoint at ActiveBrowser.SilverlightApps line and try to evaluate the object returned by the method it gives an error saying that Function evaluation timed out. and Function evaluation disabled because a previous function timed out.

Also i see the following exception in the output.

Error: PipeCommunication.AsyncPipeRead() : EXCEPTION ("Pipe Null State: False")

Type: System.Threading.ThreadAbortException

Message: Thread was being aborted.

The program '[7604] QTAgent32.exe: Managed (v4.0.30319)' has exited with code 0 (0x0).

I am using Testing framework version 2011.1.817 that is in beta. I also tried the 2011.1.712 version. I encountered similar issues.
Does the framework support XBAP automation?

Thanks.

Hello Arooj,

Your suspicions are correct; the framework does not support XBAP automation. Please see the bottom of this page for more information.

Thanks Anthony.

I'm still not able to debug my code for a simple silverlight application. Would you kindly see the code in the last post and see if i'm doing something wrong.

Hi Arooj,

Your code looks fine. The debugging trouble you are experiencing in Silverlight is a known issue. The Framework is a middle-man between Visual Studio and the Silverlight app, relaying communication. When a breakpoint is reached, the Silverlight hook is blocked and cannot execute. The debugger wants to execute, however, to retrieve values. It can't so that's why you see the timeout.
