How set ID in DAL object for use in UnitTest.

Hi Guys.

I have a need to write unitTest for services that use UnitOfWork. To do this I need to substitute of data returned UnitOfWork.
I write the following code.

var UOW = MockRepository.GenerateMock<DAL.DALUnitOfWork>();
UOW.Stub(o => o.Users).Return(new List<DAL.User>().AsQueryable());

 

I try use frameworks Moq and  Rhino.Mocks.

Do you have any solution of this problem?

See the Mindscape.LightSpeed.Testing namespace and in particular the EntityFactory class.  Help Topics > Unit Testing in the help file also has some useful tips and info.

Thanks. I found how create DAL.User with a given ID.
But i have other problem. When i try create mock object for my DALUnitOfWork (which i use in tested service)
like this

var DALUser = EntityFactory.Create<DAL.User>(EntityState.Default, userID);
var UOW = MockRepository.GenerateMock<DAL.DALUnitOfWork>();
UOW.Stub(o => o.Users).Return(new List<DAL.User> { DALUser }.AsQueryable());

i have a problem, becouse mock framework (i try RhinoMock and Moq) can't override property Users becouse it is not virtual.
If i change autogenerated file with DAL code and mark property Usersin class DALUnitOfWork as virtual all is working well.

Can you say how can I solve the same problem without changing code. Or maybe you could add some possibility  to to generate code of UnitOfWork so a set of objects would be mark as virtual.

I've added a designer option which will be included in nightly builds dated 31 July 2010 and above.

Select the model (click on the background), go to the properties window, find the Code Generation Options setting, and set VirtualQueryProperties to checked.  Then save your model, check the generated code, and the LINQ UOW properties should now be virtual.

Let us know if you run into any problems.

 i install build 01 Aug. But i don't  see the specified option.

Mea culpa.  You will need to open the .lsmodel file in a text editor and add the following attribute to the <model> element:

codeGenerationOptions="VirtualQueryProperties"

Sorry for the confusion.

thank you very much for quick response. It's working well
