I think it fails because of data source binding works differently for SL2 and SL4

I am trying to make it work with Silverlight 4 and VS2010 and I get a NullReferenceException at this line chatSession.ConnectWithRemoteUser(“ScottGu”);
Any ideas why? Here’s code:

public Page()
{
// commented out because it doesn’t exist in the current context
// according to the compiler
// InitializeComponent();

// Retrieve ChatSession instance from XAML resource declaration
chatSession = new ChatSession();
chatSession = (ChatSession)Resources["ChatSessionDS"];

// Connect with Chat Server to chat with “ScottGu”
chatSession.ConnectWithRemoteUser(“ScottGu”);
}

forgot to say, code coverage support would be a great addition too

A few of bits of feedback (I’m using the April 2010 release).

- Quite a lot of the documentation and blogs I found are out of date now (including this post). I know there is a link at the top of this post, but it points you to a site that points you back here. It would be nice to see a proper update of this tutorial.

- I’d also like support for Assert.Inconclusive.

- I could do with a way to know what unit test I am currently running in an Asynchronous test (get at Method name, and Description attribute).

- In my testing, when a usercontrol failed to be created in the [TestInitialize] method due to missing resource dictionary the test framework seemed to go ahead and run the [TestMethod] anyway which failed with a null reference exception. I’d rather see the exception from [TestInitialize].

- It would be good to be able to re-run the unit tests without re-launching the test application (or am I missing something).

- Another thing that would be cool for MVVM is the ability for me to create my UserControl and attach an instance of my ViewModel and be able to fail the test if any BindingExceptions were thrown. But BindingExceptions seem to get swallowed lower down in the framework.

Anyway, apart from that, its a very useful tool and hope to see it mature with future releases of Silverlight.

i don’t think i have any recommendations here, sorry! RIA is client-server
bridging, which is much more of a functional test rather than a unit test
for any situation.

Hi Jeff,
Thanks very much for your awesome toturial.
After i following your UI test, i got the following error:
I don’t know how to fix it, does any body can help me?
Thanks in advance!

Error 2 ‘ChatClient.Page’ does not contain a definition for ‘MessageTextBox’ and no extension method ‘MessageTextBox’ accepting a first argument of type ‘ChatClient.Page’ could be found (are you missing a using directive or an assembly reference?) C:\Project\sliverLight_test\ChatClient\Test\ClientTest.cs

Hi Jeff,
After some investigation in the internet, i haven’t found a tool which is support for Silverlight UI testing.
Is the unit Test Framework support UI testing,not only record and reply? Is it only use the method you described? Wire the related code to simulate the end user in brower?

thanks very much in advance.
-John

Jeff,
Just echo’ing E’s question – is it possible to keep resources in App.xaml?

Hi Jeff .
Thanks for the blog posts and the video.
This looks like a valueable tool.
One issue – I used option 2 (installing the template) and app.xaml.cs has 2 build errors out of the box :
1.’InitializeComponent’ does not exist in the current context
2.Cannot implicitly convert type ‘System.Windows.DependencyObject’ to ‘System.Windows.UIElement’. in the line : “this.RootVisual = UnitTestSystem.CreateTestPage(this);” .

I commented out the ‘InitializeComponent’ call and casted the dependency object to a UI element . I wonder if I did something wrong on the way ?

Thanks
Amit

Hi Jeff,
You mentioned that it’s possible to generate TRX files for the runs. Can you explain a bit more on how I can get these enabled for my tests?

Thanks.

Jeff,

Thanks for this awesome tutorial. Quick question.

Is there a way to keep resources (messagehistory and sendbutton) in App.xaml instead of moving theminto Page.xaml and still get unit test to work?

Thank you!

Jeff,

Never mind. I figured it out. I added another Silverlight link for this test project to my web project. Now service call is working.
