It might depend on the lifecycle of your code.

The tests I have for systems that keep evolving while being production critical over a decade are invaluable. I cannot imagine touching a thing without the tests. Many of which reference a ticket they prove remains fixed: a sometimes painfully learned lesson.

Also the lifecycle of your system, eg, I’ve maintained projects that we no longer actively coded, but we used the tests to ensure that OS security updates, etc didn’t break things.
