Hello,
im not able to raise events for a mocked interface defined in a .net
interop assembly (using vs2008 sp1, .net 2.0 sp2 and windows xp sp3).
If i try to raise an event on the mocked interface i'm facing a
exception informing me that "The last method call add_Click was not an
event add / remove method".
To give you an example.
[Test]
public void RhinoMocksInteropEventProblem_RaiseEvent_RaiseException
()
{
_CommandBarButtonEvents_Event foo =
MockRepository.GenerateStub<_CommandBarButtonEvents_Event>();
foo.Raise(x => x.Click += null, null, null); // <---
System.InvalidOperationException : The last method call add_Click was
not an event add / remove method
}
The _CommandBarButtonsEvents_Event interface is part of the Office
2003 PIA's (Primary Interop Assemblies). Please take a look at MSDN if
you need more information about the interface.
To my suprise, if i implement the interface in an abstract class and
mock the abstract class instead of the interface the code works.
public abstract class Workaround : _CommandBarButtonEvents_Event
{
public abstract event _CommandBarButtonEvents_ClickEventHandler
Click;
}
[Test]
public void RhinoMocksInteropEventProblem_RaiseEvent_Workaround()
{
_CommandBarButtonEvents_Event foo =
MockRepository.GenerateStub<Workaround>();
foo.Raise(x => x.Click += null, null, null);
}
So in my opinion this is a issue that RhinoMocks could handle better.
Has anyone faced the same limitation? Is this a known limitation of
RhinoMocks? Is there a better workaround?
Thanks in advance for any help.
Best regards,
Andreas Ländle
