How to Mock a Static Singleton?

Question

I have number of classes I\'ve been asked to add some unit tests to with Rhino Mocks and having some issues.

First off, I know RhinoMocks doesn\'t allow for the mock

You don't have to fix all the uses at once, just the one you're dealing with now. Add an ISomeInterface field to the class under test and set it through the constructor. If you're using Resharper (you are using Resharper, aren't you?), most of this will be trivial to do. If this is really fiddly, you can have more than one constructor, one which sets the new dependency field, the other which calls the first one with the singleton as a default value.
