[Testing Confirmation] Confirm current testing requirements

[stephen-crawford]

As part of the discussion around implementing an organization-wide testing policy, I am visiting each repo to see what tests they currently perform. I am conducting this work on GitHub so that it is easy to reference.

Looking at the OpenSearch Hadoop repository, it appears there is

Repository	Unit Tests	Integration Tests	Backwards Compatibility Tests	Additional Tests	Link
OpenSearch Hadoop				Certificate of Origin, Link Checker, Changelog Verifier	#123

I know your repository is a bit different than many of the others so if you feel certain tests are present and I am not interpreting things correctly please leave a comment.

I don't see any requirements for code coverage in the testing documentation. If there are any specific requirements could you respond to this issue to let me know?

If there are any tests I missed or anything you think all repositories in OpenSearch should have for testing please respond to this issue with details.
