New Schema: Turborepo

[hyperupcall]

Turborepo, a TypeScript/JavaScript monorepo management tool is configured using a turbo.json configuration file. This adds support for that

You need to remove package.json from "skiptest": []
"skiptest": [] is for a schema that should not be validated at all.
So no AJV validation of the schema or test etc.
This is used for schemas that were previously added to schemastore but moved to an external site. And the local schema file should still exist for a possible hardcoded URL link to the schema.
See history of https://github.com/SchemaStore/schemastore/blob/master/src/schemas/json/block.json

It is not possible to combine a local and remote schema

Extra information:
in the past the tv4 validator could download an external schema. The downside is that the build server failed randomly because sometimes it can't download the file. The remote download functionality has been removed.

See issue #2247 on external schema not available. But some URLs are permanently broken and others are not.
Why has this download failed in the past?

The file was not deleted or moved according to history:

Ah okay, it looks like I was confused. So some schemas were originally located here, but they moved to an external site, and those schema files were kept here in case their URLs were hardcoded. Now that I think about it, would this be potentially applicable in the case of xunit? That PR was merged before the single source of truth was added to CONTRIBUTING.md, and when I did the PR, I sort of copied the schema files from xunit.net for each of the versions. A mistake, in retrospect, but is that something you would be interested in me fixing (in the same style as block.json / theme-v1.json)?

About Turborepo, since it is not possible to combine a local and external schema, I have updated this PR to only add the external schema to catalog.json. Thank you for the extra information, the use of tv4 validator is interesting, especially since it doesn't seem maintained for 6ish years now.

[GerryFerdinandus]

yes, for xunit please use the external schema.

tv4 was the first and only validator at the start of this project. Later, an even better AJV validator was added. Schema that fails AJV validation is still used with the deprecated tv4 validator.
