I recently made a fresh port of SSpec from VW and added some refinements
to the mock object behaviour. This is available on Squeaksource.com [1],
however, you must not load the other packages, only the "SSpec" package,
otherwise it may not work.

To create your own SpecContext:

Subclass SpecContext
Create method category "specs"

Only methods in the category named "specs" will be run as part of the
spec, so you can use helper methods in other categories which will not run.

A few examples of specs:

	1 should equal: 1

	#(1 2 3 4 5) should include: 3

	[ #() first ] should raise: Error

	[ #(1) first ] should not raise: Error

	| mock |
	mock := self mock: 'A mock name'.
	(mock shouldReceive: #foo)
		andReturnConsecutively: #('foo' 'bar').
	SomeClass new on: mock; doSomething

Finally, to run the spec using the text runner:
TextSpecRunner verbose run: SampleContext. Transcript endEntry

I've also, literally just this second, added a Morphic spec runner to
the repository. (SSpec-jmt.11) It's quite primitive, but I find it very
handy. :)

I hope this helps,
