Non-functional attributes emerge from the system as a whole, so even a codebase with 100% coverage can have problems. Here's the thing about TDD. The definition of TDD is that you don't write code without a failing test, and you do so in a tight loop that covers one branch at a time.

To share your thoughts, join the AoAD2 open review mailing list. Test-driven development, , or TDD, is a rapid cycle of testing, coding, and refactoring. Done well, TDD eliminates an entire class of programming errors. TDD isn’t perfect, of course. TDD is difficult to add to legacy codebases. Why TDD Works.

This is basically assuming the system is correct until proven otherwise. Deciding what strategy to use depends on your risk appetite for a specific system or functionality and on how much certainty you already have.
