We have a URL object in one of our Java classes that we want to mock, but it’s a final class so we cannot. We do not want to go a level above, and mock the InputStream because that will still leave us with untested code (we have draconian test coverage standards).
I’ve tried jMockIt’s reflective powers but we work on Macs and there are problems with the Java agent handler that I haven’t been able to resolve.
So are there any solutions that do not involve using real URLs in the junit test?

Answer
When I have a class that can’t be easily mocked because it is final (or sealed in C#), my usual route is to write a wrapper around the class and use the wrapper wherever I would use the actual class. Then I would mock out the wrapper class as necessary.
