Oh yes, sorry if it sounded like I disagreed with that - I agree *very
strongly* with that. :-) I was more commenting the "end goal".

I am sorry - I knew it was on SuperSwiki somewhere but had forgotten
that Hernan Tylim actually put it on SqueakMap the other day! :-)

This last paragraph almost sounds like my current notion of the "Magic
I have an idea about the Magic Book implementation that I will try to
outline later today involving Projects, StarBrowser and SqueakMap. Well,
some of you may already see what I am getting at by mentioning those
three words... :-)

No, it is *not* science fiction! And I wasn't talking about "hypertext
links", I am talking about a real dependency link. The idea goes like
- Pick a class you want to write a tutorial about, say the class Date.
- Write the tutorial and then link the tutorial as "dependent" (not in
the package sense) on the current version of the Date class unit tests.
Voila. Whenever the testcode is changed (new version) or the testcode
isn't green anymore then the tutorial needs to be updated because it has
gone stale. Or at least there is a very good chance it has.
The idea is that the Date class can evolve without turning the tutorial
stale because the tutorial is about *using* the Date class (think
And the unit tests for class Date are also exactly capturing the
"external contract" of the class Date. So if the tests are changed or
doesn't turn green this surely can only mean that one of the following
things have happened:
- There was a bug in the test code that someone fixed. No external
contract changes. False alarm, tutorial is still ok.
- The tests has changed which implies that the external contract of Date
has also changed. Alarm. Tutorial probably needs change.
- Date is changed so that the external contract changed - the tests
fail. Alarm. Tests should be rewritten and so should probably the
Anyway, you get the picture.
