Tests don't find bugs. They find things a developer needs to investigate.

Most tests I've seen aren't aids to diagnosability, so if there is a bug, the developer is still needed to find it.

I wouldn't call this "too early," but "testing the wrong thing" if they were testing internal particulars instead of behaviors.

I want to be make sure I understand your message here. When I write unit tests, I frequently find bugs in my own code. Are you talking about something different?
