ExpectedException specification

[CharliePoole]

I subclassed ExpectedException attribute passing to super constructor AssertionException type.

Now if I attibute my test method with both my subclass and ExpectedException(AssertionException) I get runner and attribute order dependent behaviour:

• R# runner interpretes all attributes in sequence so a test method body that passes is toggled to failure by the first ExpectedException attribute then the failure is toggled back to pass by the next ExpectedException attribute.
• Nunit 2.5.3 gui-runner seems to interpret just the first one

for:

<Test()> <ObservedBehaviour("Code generator produces duplicates.")> <ExpectedException(GetType(AssertionException))> _
Public Sub ObservedBehaviourAfterChangeTest()

yielding:

 Observed behaviour has been changed. Please balance the value of the change with compatibility breach costs.
 Originally observed behaviour: Code generator produces duplicates.
 NUnit.Framework.AssertionException was expected

while for

<Test()> <ExpectedException(GetType(AssertionException))> <ObservedBehaviour("Code generator produces duplicates.")> _
Public Sub ObservedBehaviourAfterChangeTest()

returning:

NUnit.Framework.AssertionException was expected

The documentation deserves a clarification.

Closed as invalid as this is no longer relevant.

... because we no longer have ExpectedException!

Just as an explanation for the original requester. :-)
