protected function SchemataBrowserTestBase::getDereferencedSchema in Schemata 8

Retrieve the schema by URL and dereference for use.

Dereferencing a schema processes references to external schema documents and prepares it to be used as a validation authority.

This will static cache the schema so the same schema resource will not be retrieved and processed more than once per test run.

@todo Evaluate PSR-16 cache support built into Dereferencer.

Parameters

string $url: Absolute URL to a JSON Schema resource.

Return value

object Dereferenced schema object.
