Just to clarify, I am definitely not saying this is only useful or only applies to databases.

The point was more that, I don't see how this testing approach (at the level that it functions) would catch all of the bugs that I have seen in my career, and so to say "all of the bugs" or even "most of the bugs" is definitely a stretch.

This is certainly useful, just like unit tests, assertions, etc are all very useful. It's just not the whole picture of "bugs".

Yes, there are plenty of non-functional logic bugs, e.g. performance issues. I think this starts to drastically hone in on the set of "all" bugs though, especially by doing things like network fault injection by default. This will trigger complex interactions between dependencies that are likely almost never tested.

They should clarify that this is focused on functional logic bugs though, I agree with that.
