[dcvz]

This is a demo of doing tests against the Godot 4.3 runtime using godot-testability-runtime

Thank you for the contribution! 🙂

However, I do not plan on adding third-party dependencies for testing. We have our own integration testing framework, and being developed inside the project is crucial, so we can tailor it exactly to our needs and have shortest possible development cycle.

That said, your addition to ecosystem in godot-rust/book#116 definitely makes sense! Also, it might be worthwhile to include this demo in your own repository as a showcase, and maybe even run it as a periodic nightly job against latest godot-rust master to ensure it's up-to-date.

Makes sense! DIdn't realize that existed until very recently. Closing this and thanks for the suggestions!
