But "when you click on this after that this happen while it shouldn't" is usually enough info to start debugging: you have reproducible steps. Which you can do with a debugger running so you see exactly were and how things break.
And it is a lot less brittle than "well we tried to refactor some minor thing and now everything is red; but we don't know if the software behavior changed or just because our tests were just checking the implementation".
well, if you're determined to write stupid tests you can do it at any level. And that is not enough info to start debugging unless you had the machine in a known and reproducible state to begin with, which is where we get back to writing focused reproducible tests.
