Overtesting isn't lean, but TDD is a practice which fits very well within lean (particularly, its a practice which prevents waste by doing things that aren't needed, since it concretely bounds what is necessary, as well as the more-often discussed effect of preventing additional downstream waste in the form of rework because of incorrectly implemented work that gets into production.)

I'm not sure what that sentence means; it sounds like something decidedly non-lean (if something is "already proven", writing tests for it seems to be a task known to be redundant, and thus pure waste.)
