We start with hard "every module must have an end-to-end test" generally. This is a good level. Add tests as needed for debugging issues. Lately I've hit some joker boss who thinks TDD can be done without automated tests. :( The tests are semi manual (scripted), relatively slow to execute and a development bottleneck as the test machines are few. Some other jokers devs ignored even this limited testing and obvious breakage results.
