I’ve been struggling to get the framework to run in Express Edition or VS2010 and finally downloaded WP7UnitTestsSampleApp from http://smartypantscoding.com/a-cheat-sheet-for-unit-testing-silverlight-apps-on-windows-phone-7. That worked in both editions.

Turns out the test project must be targe Windows OS 7.0 or you get:
Cannot find a Resource with the Name/Key typeNameConverter [Line: 47 Position: 24]

Happy coding.

Hello Jeff,
I would like to use your Unit Framework but unfortunatley Visual Studio throws an error while creating the testPage:

XamlParseException occured
Cannot find a Resource with the Name/Key typeNameConverter [Line: 47 Position: 24]

Line 47 refers to the initial CreateTestPage:

private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
SystemTray.IsVisible = false;

47: var testPage = UnitTestSystem.CreateTestPage() as IMobileTestPage;
BackKeyPress += (x, xe) => xe.Cancel = testPage.NavigateBack();
(Application.Current.RootVisual as PhoneApplicationFrame).Content = testPage;

}

Hope you can help me out!
thank you!

Hi Jeff,

Thanks for releasing this and for your continued support of Silverlight testing

One problem I’ve found though…
We have a continuous integration server which runs our SL tests using the msbuild command line and in some cases we have a need to use the tag expression which worked great in the November toolkit release
Example:
msbuild -t:test /p:tagexpression=TagToRun

But this does not seem to work in the new version, I also tried setting the tag expression in the App.xaml.cs

Example:
UnitTestSettings settings = new UnitTestSettings();
settings.TestAssemblies.Add(Assembly.GetExecutingAssembly());
UnitTestSystem.SetStandardLogProviders(settings);
settings.TestHarness = new UnitTestHarness();
UnitTestSystem.SetTestService(settings);
settings.TagExpression = “TagToRun”;
this.RootVisual = UnitTestSystem.CreateTestPage(settings);

Thanks in advance

@Jeff: I am using the beta version in Visual Studio 2010 professional. The problem also occurs in the VS express version shipping with the beta tools.

Furthermore a small suggestion: could the start window of the WP7 unit testing app show the tags found in the tests, so we can just click it ? Since the beta emulator, the phone onscreen keyboard must be used to type text, and that takes time. The computer keyboard can’t be used anymore.
Oh, and I would also love a EnqueueConditionalWithTimeOut
kind regards,
Bert Lagaisse

@Bert,
This should be fixed in newer builds – what version of the phone tools are you using?

Hi. I watched your MIX10 video on unittesting WP7. My tests stop running because I get Visual Studio breaking on exceptions in between my test project and tested projected (when the exception is thrown at the top level public method i’m testing. I tried to disable it in the debug -> exceptions list. But no luck.

any ideas ?

greets

Hi Jeff
Thanks for your quick reply.
It is not running inside a Silverlight plugin.
It is basically just a Silverlight Unit Test Framework project where I have made all dlls copy local (except for mscorlib) and have used the nunit test framework (compiled for silverlight). I am then using the nunit-console test runner to run the nunit tests in the compiled dll of the project.
The strange thing is that in SL3 when I used this code I would be able to access the dispatcher using at least one of the methods above, but in SL4 none of the methods work(they now give the ‘agcore’ missing error), and there doesn’t seem to be any dispatcher instance that I can access.
Is there any way of instantiating the ui thread without having to run it inside the silverlight application environment (with a dependency on ‘agcore’)?

@Mark,
So is this all running inside a Silverlight plugin or not? Since the framework has a dependency on System.Windows, even if that is pulled it, it may be trying to p/invoke into the platform (SL)’s native code, which is in agcore and nptctrl…

Hi Jeff
Thanks for all the work you have done to make TDD for Silverlight at least a bit sane. I have been using your Silverlight Unit Test Framework with Silverlight 3 and did the conversions you mentioned earlier to get it running with nunit. The best thing is that I was able to run the tests from Resharper and from nunit-console.exe on my Hudson build server and display the test results I came across a problem with running tests that needed to be run on the UI Thread, but was able to work around it with the following class that I created:
public static class UIThread
{
public static void Run(Action action)
{
Dispatcher dispatcher = TryGetInstance(() => Deployment.Current.Dispatcher)
?? TryGetInstance(() =>
{
PropertyInfo propertyInfo = typeof (Dispatcher).GetProperty(
“MainDispatcher”, BindingFlags.Static | BindingFlags.NonPublic);
return (Dispatcher) propertyInfo.GetValue(null, new object[] {});
})
?? TryGetInstance(() => Application.Current.RootVisual.Dispatcher);
if (dispatcher != null)
{
dispatcher.BeginInvoke(action);
}
else
{
SynchronizationContext synchronizationContext = TryGetInstance(() => SynchronizationContext.Current);
if (synchronizationContext != null) synchronizationContext.Send(state => action(), null);
else action();
}
}

private static T TryGetInstance(Func func)
where T : class
{
T instance = null;
try
{
instance = func();
}
catch (Exception) { }
return instance;
}
}

This class was able to run the test on the UI thread in the test runner as well as in resharper and through nunit-console. My world was complete!
Then I upgraded to SL4 and none of those dispatcher calls work any more when I am running the tests outside of your test runner. Most of the calls give an error about ‘agcore.dll’ is missing. This used to work in SL3.
What would I need to do to get a dispatcher thread when running outside of the silverlight app? Any ideas? Is there some Silverlight initialisation call I can make?

Thanks
-Mark

@Jabba,
Yeah it’s a little inconsistent, it looks like there is a visual tree bug of some sort in the Silverlight plugin that is manifested in this sort of test stage situation. I’ve seen it on tests now, too.

UI and test speed much improved, thanks. I do notice that the Test Stage doesn’t show anything added to the TestPanel unless I click on the splitter, then it updates and shows every time a test add something.

Thank you for your passion. very useful.

I have a question.

=========================================================================================

I want to get the result file(.trx format) like Desktop Silverlight Unit Test Framework.

How can i generating result file in my TestApp File System ?

For desktop :

I use ‘Visual Studio Command Prompt’. Generated ‘TestResult.trx’.

ex) msbuild /t:coveragetest

I want to report an other person for testing result.

so..i want make like this App

[1] MyTestApp of WP7 drop the result file.

[2] Upload result file to Web Server.

So, I need to result file.

If UTF is not supported, i want to make this solution by reference SL3 UTF.

Is that possible ?

If possible, Where is the result making module source ?

Please help me.
