Write mock test for entity field

Question

I am trying to write mock test for following if statement:

if (Application.GetGroup("Hospital").GetEntity(i).GetField("hosp_id").GetInternalValue() == "Y")
{
    //some code.
}

I tried following:

var mockHosp = MockRepository.GenerateMock<IEntity>();
hospGrp.Stub(x => x.GetEntity(0)).Return(mockHosp);

var hosp_id = MockRepository.GenerateMock<IField>();
hospGrp.Stub(x => mockHosp.GetField("hosp_id")).Return(hosp_id);            
hosp_id.Stub(x => x.Value).Return("Y");

I keep getting InvalidOperationException on this line:

hospGrp.Stub(x => mockHosp.GetField("hosp_id")).Return(hosp_id); 

Can this be achieved?

Answer 1

假设GetField方法似乎属于IEntity接口，则应将其存入以下代码

mockHosp.Stub(x => x.GetField("hosp_id")).Return(hosp_id);

Answer 2

I finally figured it out. Putting out a solution here may be it will help someone out:

var mockHosp = MockRepository.GenerateMock<IEntity>();
hospGrp.Stub(x => x.GetEntity(0)).Return(mockHosp);
mockHosp.Stub(x => x.Id).Return("1");

var hosp_id = MockRepository.GenerateMock<IField>();
hospGrp.Stub(x => x.GetField("hosp_id")).Return(hosp_id);
hosp_id.Stub(x => x.Value).Return("Y");
