I share the same opinion. Its been a long time since I read Kent Beck's book on TDD, but I don't recall him saying TDD = unit tests. When I see people using these as synonyms it feels to me they don't quite understood what TDD means and just jumped into this conclusion of "unit tests that check every method/line of code you write".

Testing behavior from the user perspective should be the goal, these are the kind of tests that bring most value in the long run.
