@matt I didn't say it was often. It's just more often than finding real serious bugs. It's mostly things like, "it assumed I wanted to keep backward compatibility with an old API endpoint, even though there are no consumers of the old API and killing old code is actually a benefit".
I'm not convinced it's writing more bugs than I would have written in the same amount of code or that my bugs are more likely to be caught in review. I don't write 100% test coverage for any of my projects...
