AutoFixture: Configuring an Open Generics Specimen Builder

Question

I have an object model that uses Open Generics (Yes, yes, now I have two problems; that\'s why I\'m here :) :-

public interface IOGF
{
}

class C
{
         


        

Answer 1

AFICT there are no open generics in sight. D relies on IOGF which is a constructed type.

The error message isn't because of open generics, but because IOGF is an interface.

You can supply a mapping from IOGF to OGF like this:

fixture.Register>(() => fixture.CreateAnonymous>());

Since OGF relies on IX you'll also need to supply a mapping to X:

fixture.Register(() => fixture.CreateAnonymous());

That should do the trick.

However, as Nikos Baxevanis points out in his comment, if you use one of the three supplied auto-mocking extensions, this would basically work out of the box - e.g.

var fixture = new Fixture().Customize(new AutoMoqCustomization());
var d = fixture.CreateAnonymous();
