Rhino Mocks接收参数,修改它并返回?

我正在尝试写这样的东西:

myStub.Stub(_ => _.Create(Arg<Invoice>.It.Anything)).Callback(i => { i.Id = 100; return i; });

我想获得传递给mock的实际对象,修改它并返回。

这种情况是否适用于Rhino Mocks?

你可以像这样使用WhenCalled方法:

myStub
    .Stub(_ => _.Create(Arg<Invoice>.Is.Anything))
    .Return(null) // will be ignored but still the API requires it
    .WhenCalled(_ => 
    {
        var invoice = (Invoice)_.Arguments[0];
        invoice.Id = 100;
        _.ReturnValue = invoice;
    });

然后你可以这样创建你的存根:

Invoice invoice = new Invoice { Id = 5 };
Invoice result = myStub.Create(invoice);
// at this stage result = invoice and invoice.Id = 100

我没有添加IgnoreArguments()来避免使用Return()。 这是我原来的方法:

List<myEntity> GetDataByRange(int pageSize, int offsetRecords);

这是我的模拟示例:

_Repository.Stub(x => x.GetDataByRange(Arg<int>.Is.Anything, Arg<int>.Is.Anything))
           .WhenCalled(x => {
                              var mylist = entitiesList?.Skip((int)x.Arguments[1])?
                                                  .Take((int)x.Arguments[0])?.ToList();
                              x.ReturnValue = mylist;   
                            });
