* the method: testProperty().
*
* <p>The testProperty() is called, when the MultiMethodTest's testing method
* is not found in the subclass. So, by defining such methods for properties
* the standard testing behaviour can be changed.
*
* <p>The testing behaviour also can be changed by overriding compare(),
* getNewVAlue() or toString(Object) methods, or by extending PropertyTester
* class.
