> Myself, I think tests and debugging go together like peanut butter and jelly. That is, you use tests to set up a situation you want to debug The hardest things are the ones that come up in prod/after it is already deployed and there's no obvious error message or indication something is wrong. E.g. rn, I'm building a SWE agent (https://ra-aid.ai https://ra-aid.ai), and running it against SWE-bench lite. The processes will run for 5+ hours and then randomly hang. So for stuff like this, I rely heavily on: 1) Verbose logging 2) Tools that let you inspect/debug running processes, e.g. py-spy.
