We are getting error when trying to launch internet explorer in a silverlight test (coded, not recorded). Internet explorer is launched correctly, but we get an exception:

Setup code:

manager = new Manager(new Settings {

EnableSilverlight = true,

RecycleBrowser = true,

DefaultBrowser = BrowserType.InternetExplorer,

ClientReadyTimeout = 50000,

ExecuteCommandTimeout = 60000,

ExecutionDelay = 100,

WaitCheckInterval = 500,

SimulatedMouseMoveSpeed = 0.5f,

EnableUILessRequestViewing = false,

QueryEventLogErrorsOnExit = false,

EnableScriptLogging = false,

AnnotateExecution = true,

AnnotationMode = AnnotationMode.All,

LocalWebServer = LocalWebServerType.None,

BaseUrl = "http://myurl/"

});

manager.Start();

manager.LaunchNewBrowser();

manager.ActiveBrowser.NavigateTo("/mypage.aspx"); // <-- Exception here

MyApp = manager.ActiveBrowser.SilverlightApps()[0];

Exception:

Exception thrown attempting to launch Internet Explorer. Please make sure Internet Explorer is properly installed and you are able to launch it.

It worked fine on my local machine, but now I am attempting to run these tests on our build server, but it does not work. I've followed all the steps here, but no luck. Still get the error:

System.ApplicationException : Exception thrown attempting to launch Internet
Explorer. Please make sure Internet Explorer is properly installed and you are a
ble to launch it.
----> System.TypeInitializationException : The type initializer for 'ArtOfTest
.Common.Win32.Connector' threw an exception.
----> System.NullReferenceException : Object reference not set to an instance
of an object.

g pipename)

I have verified that it is opening IE 8 32 bit version and all the settings are correct. Any ideas?

Thanks,
Jon

Hello Jonathan,
what version of Test Studio are you using? Please go ahead and upgrade to the latest available version of Test Studio (1117). You can download it from your Telerik account. Are you getting the errors with FF/Chrome when running tests against a Silverlight app?

On the IE problem that you're experiencing on the non-local machine:
looking at the stack trace I'm inclined to think this is the same issue (test project is built in x64). Please check closely whether this might be the problem.

All the best,

Hello Greg,
we determined that Jon didn't have the free Telerik Testing Framework installed on this build server. Because of this the required Telerik DLLs were not present on that machine. Telerik Test Studio/Run-time edition/Telerik testing framework (only one) must be installed on a machine intended for test execution (even if you're using a different runner like Nunit's runner in Jon's case).

Greetings,
Stoich

Hi, I am seeing this issue with version TTF 2011.2.1117 with the following config: Win 7 x64, VS2010 with test project built against x86, NUnit 2.5.10.11092 running nunit-x86.exe, IE9. I have uninstalled and reinstalled TTF and setup IE9, but am still having the issue.
