Using Rhino Mocks from VB.Net
I don't get a lot of chances to work on VB.Net, but when I do, it is almost always because someone has a problem with my code (or their code), and I need to look at it. The problem is that I like the syntax (sort of booish :-) ), but I keep trying to think about it like C#, so I keep getting wierd compiler errors. I am probably the only one who learns the VB syntax from opening reflector and switching to the VB.Net view.
Anyway, I was asked how you can mock event registration with Rhino Mocks in VB.Net, and here is the answer:
<TestFixture()> _
Public Class RhinoMocks_InVB
<Test()> _
Public Sub UsingEvents()
Dim mocks As New MockRepository()
Dim lv As ILoginView = mocks.CreateMock(Of ILoginView)()
Using mocks.Record
AddHandler lv.Load, Nothing
LastCall.IgnoreArguments()
End Using
Using mocks.Playback
Dim temp As New LoginPresenter(lv)
End Using
End Sub
End Class
Where the objects we are test are:
Public Interface ILoginView
Event Load As EventHandler
End Interface
Public Class LoginPresenter
Public Sub New(ByVal view As ILoginView)
AddHandler view.Load, AddressOf OnLoad
End Sub
Public Sub OnLoad(ByVal sender As Object, ByVal e As EventArgs)
End Sub
End Class
