Mocking and IQueryable<T>

Question

I've ran into a problem while trying to test following IRepository based on NHibernate:

public class NHibernateRepository<T>: Disposable, IRepository<T> 
    where T : IdentifiableObject
{
    ...

    public IQueryable<T> Query()
    {
        return NHibernateSession.Linq<T>();
    }
}

How on the Hell to mock returning IQueryable<T> out in the way that it returns given collection in exchange certain expression. I feel I have some misunderstanding of IQueryable<T>...

Answer 1

In Moq it would be:

mockRepository.Expect( r => r.Query() ).Returns( myEnumerable.AsQueriable() );

In RhinoMocks it would be:

Expect.Call( repository.Query() ).Return( myEnumerable.AsQueriable() );
