Shim :- Modifies the compiled code of your application at run time so that instead of making a specified method call, it runs the shim code that your test provides. Shims can be used to replace calls to assemblies that you cannot modify, such .NET assemblies. When To Use As a general practice it is recommended to use Stubs for ...
