Test Coverage and Integration Gates

[Schmoho]

Given the renewed activity on this repo I think it is a good idea to increase the test coverage drastically and integrate tests in automated PR gates.

Apart from guarding against regression, I see this as the main instrument to actually judge the behaviour of more extensive PRs that maybe are not really realistic to do full code reviews on.

I know this is not much of an issue at this point, I mostly set it up to redirect discussion here.

I completely agree. Implementing automated PR gates for test coverage is a great move for the repository's long-term stability, especially with these larger architectural changes.

I will make sure to include dedicated tests for both the Antimony constants and the Visitor pattern in my open PRs!
