I hope you are not true at all.

Software like a Database should have an extensive test bench with concurrency tests, all corner cases etc.

I'm not here running the new version on production to tell the maintainer/devs that my 'production unit tests failed'.

What is this even for logic?

I mean there is balance when i write tests for my production software, but my software is used by me. If i would have a library, i would test everything.

And there was some blog post about another database system were they even virtualized the File access to test cases like when the disk controller stops working.
