junit-objects is different from Junit in that it allows you to assert the state of objects and design patterns rather than the result of method calls. It should be seen as a replacement for previous unit testing frameworks.

* junit-objects focuses on testing objects: their structure, state and behavior.
* An object's state is asserted with testing protocols.
* JO greatly reduces the amount of code in a unit-test in this manner; allowing you to "bolt on" (and reuse) assertion sequences anywhere, with no change to your test methods.
* When an object changes state (its properties and behavior), you can assert that the change is deterministic and well-behaved.
* JO profiles let you assert design patterns and anti-patterns to keep your objects consistent and well-behaved.
* Also use JO profiling to root out design entropy (let JO suggest where objects may benefit from using a particular design pattern).
