> little to no automated tests

I'm still amazed people don't achieve extremely high test quality, since you get tests "for free" now.

One of the limitations of testing were always that people "design" things so they're hard to test.

And then they argue "This can't be tested", or "Refactoring this for testing is not worth it."

It is now. Yet, I work on codebases with no tests and lots of yolo co-authoring.

You get quantity of tests, but the tests are not good quality by default, at all.
