Question

I have a read-only dictionary on a dependency that I’d like to be able to stub with return values, and check that assignments to it have happened.

I was hoping that Rhino.Mocks would create an empty dictionary for me by default, but unfortunately it doesn’t. Since it is read-only, I can’t create a new dictionary and assign it to that property.

I was hoping to be able to stub it instead. From what I understand, the C# syntax for this would looking something like this:

m.Stub(x => x.myProperty).Return("abc");

So I was hoping that this would work for VB:

m.Stub(sub(x) x.myProperty).Return("abc");

But it doesn’t (compiler error). Any ideas on how to accomplish this? I’m open to the Expect/Verify syntax if it can accomplish this…

Answer 1

Using Function will do the trick:

m.Stub(Function(x) x.myProperty).Return("abc")

If you want to verify whether myProperty got called you could use Expect instead of Stub:

m.Expect(Function(x) x.myProperty).Return("abc")

// Some code here

m.VerifyAllExpectations()
