Better yet, use the MbUnit v3 Assert.Throws<> syntax (borrowed from
xUnit.Net) which returns the exception object so you check other details as
well.
SomeException ex = Assert.Throws<SomeException>(() =>
subject.DoSomething());
Assert.AreEqual("Boom!", ex.Message);

The [ExpectedArgumentException] is used to test to make sure that an
exception is thrown. If it is not thrown, then you get a failed test with
an ExpectedExceptionNotThrownException (or something like that).
Make sure that you specify the typeof exception you are looking for at the
finest granularity you can. If you set the typeof to be Exception, than any
exception thrown will pass. If you want ArgumentNullExpection to fail, then
specify the exact exception you are looking for (e.g.
ArgumentOutOfRangeException)

Subject: MbUnit ExpectedArgumentException strangeness
Here's what I observe in a test fixture I'm writing:
Given: a test method decorated with [ExpectedArgumentException].
When: the system under test throws an ArgumentNullException.
Then: The test passes.
This seems wrong to me... Am I misundertanding the semantics of
ExpectedArgumentException?
