gist example and test data

Test data

tests/data/ holds YAML instances named <ClassName>-<anything>.yaml, where the part before the first hyphen must be a class of the gist LinkML schema. Its subfolders divide the data:

• valid/ holds data that must validate;
• invalid/ holds counter-examples that must fail: Account-name-not-text, Organization-undeclared-slots and Person-slot-outside-domain;
• problem/valid/ and problem/invalid/ are for cases the current schema does not yet handle, and are empty.

In valid/, Account-basic, Organization-sample, Person-example and System-example give the name and description that every class carries. GeoPoint-spire, Magnitude-with-unit and UnitOfMeasure-foot also give slots that their class carries because a property’s rdfs:domain names it.

tests/test_data.py (10 tests) validates each file against its class with closed classes, as linkml-validate does. A valid file must give no result. A counter-example must give exactly one result, and its message must contain the reason that REASONS in the test gives for that file. just test also converts the files with linkml-run-examples into the git-ignored examples/output/.
