API tests for PUT /eholdings/providers/{providerId} endpoint are in https://github.com/folio-org/folio-api-tests/blob/master/mod-kb-ebsco/mod-kb-ebsco.postman_collection.json

If we import the collection into Postman client, we should be able to see good folder structure and providers/PUT provider by providerId has Positive and Negative test cases defined.

Run these existing API tests against mod-kb-ebsco-java endpoint, observe passing and failing tests. Copy the passing tests as is to mod-kb-ebsco-java postman collection and identify issues with failing tests. Either the failing tests have to be fixed for error messages or tweaked based on the type of failure.

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 valid justification for deleting existing tests from being copied over from mod-kb-ebsco collection to mod-kb-ebsco-java collection should be provided in the PR request.
