Shims Vs Stubs

Question

Can anybody tell me when can we use shims and stubs, its implementation, why to use them and its limitations over SharePoint 2013. I went through this link https://msdn.microsoft.com/en-us/library/hh549175.aspx . I understood some of the things but not completely. Please guide me in this.

Answer 1

I would spend some time learning to unit test on a non-SharePoint project first, otherwise you will probably find yourself getting frustrated with the process.

but the long and short, in an extremely generalized view: shims are for functions (like overriding DateTime.Now), stubs are for implementations (interfaces, abstract classes).

Answer 2

Hi,

From your description, my understanding is that you get have doubt about Shims and stubs.

Shims and stubs are part of the new Microsoft Fakes Framework. You could find how to implement these two method from this article:
