Create a test suite

[cinc]

We need a test suite for regression testing when working on the NOM kernel. From the top of my head I can think of the following.

• Subclassing
• Several level deep subclassing
• Method overriding
• Method oberriding from a class some levels higher than the current one
• Instance variable testing
• Mixing classes with and without instance variables when subclassing
• Testing the methods of NOMObject/NOMClass e.g. is the result of nomQueryInstanceSize() correct
• Do explicit meta classes work

These testcases are needed for normal classes and meta classes.

Most of this stuff is trivial with a few medium level test cases.

There must be some test case to trigger garbage collection of memory. This can be done by allocating a huge amount of different objects with siginificant memory demands.

There is support for unit testing using the class NOMTestCase by now. A few testcases are already implemented.
