Started small with minimal changes and tests. I'll create PRs project by project after this is accepted.

I started small with minimal changes. Whenever an issue is merged, I’ll work on the next one. Until we got 90% coverage, I'll proceed. Then, I'll go on with DnsServer.

Thanks for the PR. Will review it soon.

I have several unit test branches waiting for this review.

I have several unit test branches waiting for this review.

I need some time since there are too many outstanding issues. So please bear with the delay.

I am fine with the timing and delays as long as we are clear it is okay to develop unit tests for robustness. I would not like to spend time on these if you don't want to proceed that way.

If I had issue with unit tests then I would have already mentioned it.
