Re: MbUnit and VS 2008 Integration. ExpectedException tests missing from Test View window.

[Jeff Brown]

The VS integration may be encountering some kind of exception while performing reflection over the ExpectedException attribute.  Specifically, it might have to do with the "Type" parameter.

Not sure off-hand but it would be interesting to see whether VS is internally throwing exceptions while enumerating these tests.

This works great, however when I decorate a Test with an
ExpectedException attribute, the test appears to be removed from the
Test View window.  If I open the Gallio UI, the test appears as
expected.

Does anyone know why tests that are decorated with the
ExpectedException attribute are not visible in the Visual Studio Test
View window?

Thanks in advance,

Hi Jeff – I think you may be on to something.

I had not noticed that the following text was being sent to the ‘Test
Output’ window when Visual Studio was rendering the tests.

[error] An exception was thrown while exploring tests.

For info, my ExpectedException attributes look like this, and they are
being successfully rendered through the Gallio front-end.

[Test]
[ExpectedException(typeof(FaultException<SystemFault>),
"Expected Exception message here...")]
public void MyTest()
{
}

[Test]
[Row(null, null, ExpectedException =
typeof(FaultException<SystemFault>), ExpectedExceptionMessage =
"Expected Exception message here...")]
public void MyTest2(int[] x, int[] y)
{
}

I am using Gallio bundle 3.1.397. Let me know if you need any more
info.

We've had a few bugs related to the, rather antiquated, version of Mono.Cecil we're using. It's on the list of things to fix (and pushing it's way to the front!). Could you raise an issue here please and, ideally, attach a sample that reproduces the error? Thanks.
