Good news, I don't think these changes need to be tested. The notebook, search-tester, and ppr-disharges-for-mhr were used for migrations which completed years ago. Document-delivery-service is still in prod but soon to be replaced by jobs/permanent/secured-party-notification. Thor actually created the document-delivery-service job and is working on the update, so you can check with him, but I am pretty sure no testing is required.
