Question

I tried to make an unit test for this method which is pretty simple only add an object into the data base and if it works well returns true

Public Shared Function CrearCliente(ByVal cliente As Cliente) As Boolean
    Try
        db.Cliente.Add(cliente)
        db.SaveChanges()
        Return True
    Catch ex As Exception
        Throw New Exception("ocurrio un error guardando al cliente")
    End Try
End Function

Now here’s my test

<TestMethod()>
Public Sub CrearClienteTest()
    Dim mock = New Moq.Mock(Of Cliente)
    Dim actual As Boolean
    mock.Setup(Function(x) x.Nombre).Returns("blah")
    'mock.Setup(Function(x) x.Apellido()
    actual = Class1.CrearCliente(mock.Object)
    Assert.AreEqual(True, actual)
End Sub

Pretty easy my question is why when Debugged the test throws this error

Invalid setup on a non-virtual (overridable in VB) member: x => x.Nombre

What could be wrong? do i need another configuration?

Answer 1

As the error states, Moq requires that the member you mock be Overridable.
