[MO-java-dev] [SUBMISSION] com.mockobjects.test.TestNull

[<fra...@ya...>]

Hello again !

I added tests in equality to assert that null objects are not equal to other
classes of objects.  I tested against a string with the same value as the
null's description, and against java.lang.Integer.  I guess that at least tests
the simple cases.

A question:  If Null is subclassed, should the subclass still be equal to Null
?  If I get directions on how you would want to process that, I'll write the
proper test case.

Thanks !
Francois Beausoleil
