c# - 使用 Rhino Mocks 模拟 IObjectSet

Question

有没有办法使用 Rhino Mocks 为 IObjectSet<T> 生成 stub ？

我要的是类似下面的代码:

var context = MockRepository.GenerateMock <IContext>();
//generate stub
var mockProjectObjectSet = MockRepository.GenerateStub<IObjectSet<Project>>();
TestObjectSets.GenerateFakeProjectList(mockProjectObjectSet);
context.Expect(p => p.Projects).Return(mockProjectObjectSet);
var projectRepository = new ProjectRepository(context);

在GenerateFakeProjectList静态辅助方法，我只是简单地创建指定类型的对象并通过 AddObject 将它们添加到 stub 中IObjectSet 上的方法:

public static IObjectSet<Project> GenerateFakeProjectList(IObjectSet<Project> projectsObjectSet)
{     
   projectsObjectSet.AddObject(new Project()
   {
     Categories = null,
     DateCreated = DateTime.Now.AddDays(-10),
    .......

我知道我来晚了，但这是 IObjectSet<T> 的简单实现我以前用过的。我忘了我从哪里得到的:

public class MockObjectSet<T> : IObjectSet<T> where T : class {
        readonly List<T> _container = new List<T>();

        public void AddObject(T entity) {
            _container.Add(entity);
        }

        public void Attach(T entity) {
            _container.Add(entity);
        }

        public void DeleteObject(T entity) {
            _container.Remove(entity);
        }

        public void Detach(T entity) {
            _container.Remove(entity);
        }

        public IEnumerator<T> GetEnumerator() {
            return _container.GetEnumerator();
        }

        IEnumerator IEnumerable.GetEnumerator() {
            return _container.GetEnumerator();
        }

        public Type ElementType {
            get { return typeof(T); }
        }

        public System.Linq.Expressions.Expression Expression {
            get { return _container.AsQueryable<T>().Expression; }
        }

        public IQueryProvider Provider {
            get { return _container.AsQueryable<T>().Provider; }
        }
    }
