API tests for GET /eholdings/resources/{resourceId}?include=provider endpoint are in https://github.com/folio-org/folio-api-tests/blob/master/mod-kb-ebsco/mod-kb-ebsco.postman_collection.json
After importing the postman collection into Postman, there is a folder "resources/GET resource by resourceId" containing both positive and negative test cases for this endpoint.

Run the existing tests against the developed endpoint in Java and look for discrepancies. If the tests pass, copy them over to the mod-kb-ebsco-java postman collection. If any existing tests fail, figure out why they are failing and tweak tests/code accordingly. Feel free to add more test cases in case they are missing in the existing Postman collection.

Acceptance Criteria:

• As development of endpoints progresses, ensure that API tests are being maintained/developed as well.

• Code should be reviewed and approved by peers and all tests should be passing.
