What is the most well-tested code you know of and what can it teach us?
A read through how SQLite is tested (https://sqlite.org/testing.html) makes me realize how much more I could be doing to check my code is always correct. I'm not writing anything where a bug would mean life or death, but knowing a service won't crash overnight makes me sleep easier. What else can I look to for inspiration?
I saw your title, and my team is currently doing a focus on testing this week and was ready to tell you about the testing for Sqlite. Now I'm sad that I don't have other examples at the ready.
