alt Hacker NewsI may have missed it but are those tests written by person or generated? Otherwise how do you know they even test anything (like actually test, not appear to test)

It’s all written by AI and you can’t tell for sure if the tests are good. You can eyeball some but eyeballing 50k lines of code takes a lot of time. You just trust AI and YOLO, find errors later
Ask AI to find the weakest tests. :)
No joke: it works for me. I have a 45kLOC prod code (just code, no comments, no blanks), tested by a 30kLOC test code containing 1600 tests (that run in 30secs).
I helped with the test infrastructure/architecture. Sometimes I had to write the first few tests of a particular kind, but now Claude TDDs for me.
A fair share of my CLAUDE.md instructs in how I like my tests, when to write them (first), different types of tests (unit, faked-services, db, e2e, etc.)
Asking Claude to find weak tests has helped a lot in getting here. I also do review AI-gen'd code, pretty much line-by-line, before accepting it.
