So, what is the solution? Senior engineer looks over PR and signs LGTM? That is just "vibe testing". The worst kind of testing. I think the author is right, setting up tests to form a reactive environment for coding agents will lead us to a new golden age. If you later find some issue with your test case coverage, you expand it. But it is good to do it from the start as throroughtly as possible.
