The author was asked to put together examples of how to mock Java constructs well know for their testability issues. He calls these techniques unusual mocking.

If you have to test methods handling complex objects or voluminous data, you easily end up with a bunch of unreadable assert statements. The visual approach featured by MagicTest allows you to write such tests very efficiently. To prove this, the author invites you to a testing challenge.
