I am taking a look at the AAA syntax and bumped into some issues
converting
the above test. This is what I have done:
Used shared GenerateMock, GenerateStub..
view = MockRepository.GenerateMock(Of IObjectSelectionView)()
domain = MockRepository.GenerateStub(Of ObjectSelectionDomain)
()
Modified the test to look like this, I think I got most of it to work
but I'm struggling
with the view...
<Test()> _
Public Sub It_should_return_a_validationresult_errormessage_aaa()
' Arrange
Dim validationResult = New ValidationResult("Search String Too
Short!")
' Act
domain.Stub(Function(e As ObjectSelectionDomain) e.GetObjects
(Nothing, Nothing)).IgnoreArguments().Return(New List(Of
ObjectDto)).OutRef(validationResult)
view.Expect(Function(e As IObjectSelectionView)
e.ErrorMessages = validationResult.ErrorMessages)
Dim presenter As ObjectSelectionPresenter = New
ObjectSelectionPresenter(view, domain)
presenter.GetObjects()
view.VerifyAllExpectations()
End Sub
The compiler doesn't like the way I call view.Expect with the write-
only ErrorMessages property. Is
there some other way to set a call expectation on write-only
properties? Can't seem to get it working.
Right now I really miss developing in C# :o)
Thanks!
