example of failing test on related_field

[darduf]

In relation to this issue - where schema tester was failing with an UndocumentedSchemaSectionError on our OAS definitions that uses DRF JSON:API RelationshipView

We would expect the schema tester to successfully index /api/pet/{petId}/relationships/owner/

FAILED tests/test_django_framework.py::PetsAPITests::test_create_pet_owner_relationship - openapi_tester.exceptions.UndocumentedSchemaSectionError: Error: Unsuccessfully tried to index the OpenAPI schema by `/api/pet/{petId}/relationships/{relatedField}/`. 

Undocumented route /api/pet/{petId}/relationships/{relatedField}/.

Documented routes: /api/pet/
	• /api/pet/findByStatus/
	• /api/pet/findByTags/
	• /api/pet/{petId}/
	• /api/pet/{petId}/relationships/owner/
