An adjacent point is to use checked exceptions and to handle them appropriate to their type. I don't get why Java checked exceptions were so maligned. They saved me so many headaches on a project where I forced their use as I was the tech lead for it. Everyone hated me for a while because it forced them to deal with more than just the happy path but they loved it once they got in the rhythm of thinking about all the exceptional cases in the code flow. And the project was extremely robustness even though we were not particularly disciplined about unit testing
