Basic/Simple testing question

RichM posted on Friday, October 05, 2007

We're just getting started with CSLA.NET after spending the last 8 years developing with our version of Lhotka's VB6 COM/MTS framework.

Having been used to doing quick unit testing via the immediate window in VB6, I tried this in VS2005 using some classes we'd written and tested with a simple UI.  However, I've been unsuccessful creating a new instance of a class that inherits BusinessBase.  I can create an emply class, let's say Class1, and do the following in the immediate window:

oo = new Class1

However, trying the same with a class that inherits BusinessBase does not work.  Here's a simple, sample class:

<Serializable()> _
Public Class SomeClass
    Inherits BusinessBase(Of SomeClass)

    Private mcProperty As String

    Public Property SomeProperty() As String
        <System.Runtime.CompilerServices.MethodImpl(Runtime.CompilerServices.MethodImplOptions.NoInlining)> _
        Get
            Return mcProperty
        End Get
        <System.Runtime.CompilerServices.MethodImpl(Runtime.CompilerServices.MethodImplOptions.NoInlining)> _
        Set(ByVal value As String)
            mcProperty = value
        End Set
    End Property

    Public Shared Function NewClass() As SomeClass

        Return New SomeClass

    End Function

    Protected Overrides Function GetIdValue() As Object
        Return 1 ' Don't care - just testing
    End Function

End Class


Trying to do the following in the immediate window:

oo = SomeClass.NewClass

results in the error "Unable to evaluate expression."

For a more complex class that works when accessed via a Windows Form project, we get an error "SomeClass" is an unsupported type"

Is there some trick or environment setting to make this work?

I work in C# and rarely in the immediate window but don't you need to specify the "()" for the function call?

i.e. oo = SomeClass.NewClass()?

For a second I thought I was being real stupid.. Anyway - same error with or without the ().  I had also tried a different factory method in another class similar to what Joe posted:

oo = SomeClass.GetClass(123)

with the same results.

FWIW,

I was using a Web Project - not Winforms.

I set a breakpoint in my code (happened to be in a BO) and then opened the Immediate window and requested a completely different BO. I set a breakpoint on the factory method and it worked. The code stopped there and I was able to step through the Data Portal and retrieve the BO.

oo = Acct.NewAcct("11602")

?oo.Acctcode

"11602" {String}

String: "11602"
