Just what bert said. A method for a morph subclass that overides or extends the inherited method. I just said it in an unusual way.

The answer is it depends on the morph. Why are you trying to outguess the standard protocol? Any gain in speed is lost in having the test depend on the morph in question not doings anything special when deleted. Wouldn't this make the test rigid and fragile? 

When I write morph tests with examples I set up a testcases ivar with a list. In the test anything that needs deleting is added to the list.
The tear down iterates over the list deleting the morphs then nils out the ivar . 

Since I'm lazy I do this for one test class and sub class other test classes to that one when such behavior is needed.

Keep up the good work.
