  • This is the kind of AI stuff that really annoys me. Looking at one of the mutation examples I didn’t see anything that wouldn’t normally be tested by a typical mutation tool. You took a simple, idempotent process and you got an llm to do it slower, less accurately, and using more resources.

    If you wanted to marry the two in a new and possibly useful fashion I would say use an llm to analyze the results of a standard mutation test and give guidance on what issues should be acted upon first. An off-by-one calculation could mean somebody loses a million dollars or it could mean a button is grayed out. Standard mutation tools don’t give you that context.













  • Got hands on experience with this. Wasn’t my design choice but I inherited an app with a database where one of the keys was tied to a completely separate database. I mean at the time it probably made sense but the most unlikely of scenarios actually happened: that other database, the one I had zero control over, was migrated to a new platform. All of those keys were synthetic so of course they were like, “Meh, why we gotta keep the old keys?” So post-migration my app becomes basically useless and I spent 6 hours writing migration code, some of it on off hours, to fix my data.

    So it’s questionable whether a foreign key of a completely different system is a natural key, but at the very least never use a key YOU don’t control.
