Creating Test EntityList objects - RIA Services

Question

I'm creating an EnityList to do some client side testing with my ViewModel. Something like:

   var people = new EntityList<Person>()
    {
        new Incident() {Age = 55, Name="Joe"},
        new Incident() {Age=42, Name="Sam"}
    };

The problem is that the implicit (and explicit) Adds fail. The entitylist is created as read-only. Any thoughts on how to create a test EntityList?

Answer 1

I think you also need an EntityContainer to own your EntityList.

Answer 2

If you're doing testing then you probably don't want an EntityList. I would expect that a ViewModel shouldn't know about the EntityList, but rather should just get access to an IEnumberable instead. Both EntityList and List expose this, so in your tests you can just create a List.

I realize this doesn't help with the issue of EntityList being read-only. :)
