The Hayes tester and its descendent, ttester. Gerry Jackson maintains
a suite of unit tests for the standard words:

where you can see usage examples.

IMO the Forth core wordset and its associated test programs tester.fr and core.fr
should run on any Forth system. It is the "agreed" bare minimum.

If it does not, the system is incomplete or presents a diverging dialect.

Bear in mind that more complete Forths are practically always full of
very individual (application domain specific) language extensions.

What I was after originally was not a "test suite" but a "unit test library". I'm not really interested in establishing whether the Forth is compliant with a Forth standard. I'm more interested in working within the pedagogical framework of Exercism.

No disagreement there.

My apologies. Okay, that's very interesting. I shall look into it further.
