A green bar at this stage should *not* be taken as a pass, but only an indicator that the code now fullfills its contract. That is insufficient to pass the code. Branch and boundary coverage simply can't be analyzed until after the code is written.

While I take your point, the test-first response would be that if boundary behavior is important then it forms part of the code's contract, and so there should a test for it.

Branch and statement coverage should come out at 100% if you've been doing TDD properly, since you shouldn't have been writing any code that wasn't motivated by a failing test.

Not that whitebox testing and coverage tests are useless of course - but with a team doing TDD they're much more useful as pointers to where areas where TDD is being skipped or done poorly.
