HttpPostedFileBase is an abstract class. In your test, just create a new class inheriting from it and create your own stub version (hardcoding the method results you need to test). What style of testing are you doing?

• mocking (testing for interaction)
• stubbing (testing with known values)
• fakes (using simpler objects to accomplish the task, not necessarily production code).

I think here stubbing would be most appropriate.

Alternatively, you could use Moq (or another framework) to help with this.
