Opening a discussion about the test suite.

• What do we need to test as a priority?
• Which framework (e.g., GoogleTest)?
• Running tests in CI/CD.

HI @cantordust , I stumbled across this discussion because.... I wanted to open a discussion about which testing framework to use. As for my preference, I think I would go with googleTest indeed, just because it seems to be the standard these days, I understand is quite stable and has a lot of functionality. But if any of you have a different preference I'm happy to try, no real strong opinions here.
