What is the Shadowing attribute that the VS uses when it generates unit tests?

Question

When i generated unit tests the Visual studio added some fictive class that mocks my class and added the "Shadowing" attribute. What does it do?

Answer 1

Did some research and found this. Apparantly, the [Shadowing] attribute is used by MSTest when it creates an accessor class that allows you to call a private method on a class as if it were public.

So when you're unit testing a private method of a target class, that private method will be available to you via the accessor wrapper class for the target class.
