How To Test Schema Org Structured Data Validation In Google You have it almost valid the behavior i mentioned applies only before draft2020 so we should add tests to 3 directories: draft2019 09, draft7 and draft6 (and not to draft2020 12 the additionalitems keyword doesn't exist there anymore in the new versions of the specification). This page focuses on how these keywords are tested in the test suite, their behaviors across different json schema draft versions, and how they interact with each other.
Test Unevaluateditems With Nested Items With Invalid Additional Item The items keyword can be used to control whether it's valid to have additional items in a tuple beyond what is defined in prefixitems. the value of the items keyword is a schema that all additional items must pass in order for the keyword to validate. This keyword only has an effect when the sibling items keyword is set to an array of schemas. if items is not present or is set to a schema (not an array of schemas), additionalitems has no effect and is ignored. As you can see from the json schema spec (above), the rules resulting from the combination of 'additionalitems' and 'items' keywords are quite complex and not at all intuitive. in order to make the user interface intuitive and simple to use these values are encapsulated into "array items container". This schema will be applied to all array items that were not evaluated by other keywords for items (items, additionalitems and contains) in the current schema and all sub schemas that were valid for this data instance.

To add a schema to validate the additional array items, use the context menu 'add array items > additional items' from the parent schema or the array item container. The sanctity of data is one of the most important things to test when testing apis, especially when dealing with downstream systems. testing your api response against the json schema standard is one way to achieve this. Maybe this is just a question: for schema type 'array' how are 'items' and 'additionalitems' expected to work together? i have yet to hit on a valid combination in strict mode.
